Le Bosquet del Vau un établissement du néolithique final

Summary:The Neolithic site of the Bosquet del Vau is located in the Brabant Province in Belgium. Two different rescue excavations took place on the site both in 2006 and 2007 : the first was subsequent to a housing project of about 110 houses, the latter to the building of the R.E.R. (Express Regional Transportation System).The site was discovered in the 1980 by a group of three teenagers going flint tools hunting all around Waterloo and Braine l’Alleud. Flint tools pertaining to the Late Neolithic and Early Bronze Age were recovered on site as well as some Mesolithic flint tools.The site is located on a small sandy hill and covers 2.5 hectares. Steep slopes surround it to the west and north-west and gentler ones to the northeast and south, an isthmus exists to the east linking it o the plateau.The settlement is protected by a palisade to the east and south, a wide ditch links the palisade to the nearly valley to the west. The western side of the hill has seen its slope artificially steepened as did part of the northern side. No palisade was found on either of those two sides.Part of one house and a complete second one were discovered in 2006 and 2007. They are aligned north to south, 18 meters long and 4.5 meters wide. A narrow ditch houses the post holes, posts are maximum 0.30 m in diameter and spaced evenly. Central posts suggest a two-sloped roof. No hearth was found inside of the first house, the one of the second has yet to be associated with the house.A phosphate map was made in both cases, evidence points to a house divided into three parts, with maybe a cattle area next to the second one.Potsherds recovered in two postholes of the 2007 house fit together and could be dated to the Late Neolithic Period.Flint tools are mostly micro-denticulates though a few polished axes fragments have been discovered as well as arrowheads and a beautifully knapped flint knife.The various types of stones used: from black flintstone to Parisian flintstone and phtanite suggest here again a Late-Neolithic dating.

Spatio-temporal distribution of shallow very-low-frequency earthquakes between December 2020 and January 2021 in Kumano-nada, Nankai subduction zone, detected by a permanent seafloor seismic network

We estimate the hypocenter locations and the centroid moment tensor solutions of the shallow very-low-frequency earthquake (sVLFE) activity that occurred in the Kumano-nada region of the Nankai Trough megathrust zone in central Japan from December 2020 to January 2021. Using seafloor observation data, we examined the detailed spatio-temporal distribution of the sVLFE activity. During this episode, the activity area was within the vicinity in which the sVLFE activity has been observed in the past and can be divided into two major parts. The sVLFE activity started from the eastern side and remained there for the first 5 days and then migrated to the western side via secondary expansion. The eastern active area is located just below the outer ridge and coincides with the location where the paleo-Zenith Ridge subducted. The western activity area is centered between the outer wedge and the outer ridge with the primary active area being at the outer wedge. Comparing the activity in the eastern and western areas, the eastern side is more active, but the individual moment releases on this side are smaller than those on the western side. This may indicate a difference in the fluid pressure along the plate boundary between the eastern and western areas. After the second expansion of the active area, we observed several migration patterns within the expanded area with a faster velocity than those of the initial and second expansions. The direction of these migrations is opposite to that of the first and second expansions. This indicates that the fluid pressure and/or stress level in the sVLFE generation region changed with time within this episode. Furthermore, many waveforms with sVLFE characteristics were observed at only one or a few observation points near the trough axis in the middle to latter half of January 2021. This indicates the occurrence of small-scale sVLFEs in the vicinity of the trough axis at the end of this sVLFE episode. Graphical Abstract

New age constraints on magmatism and metamorphism in the Morin terrane (Grenville Province, Quebec)

The Morin terrane is an allochthonous crustal block in the southwestern Grenville Province with a relatively poorly-constrained metamorphic history. In this part of the Grenville Province, some terranes were part of the ductile middle crust during the 1.09–1.02 Ga collision of Laurentia with the Amazon craton (the Ottawan phase of the Grenvillian orogeny), while other terranes were part of the orogen’s superstructure. New U-Pb geochronology suggests that the Morin terrane experienced granulite-facies metamorphism during the accretionary Shawinigan orogeny (1.19–1.14 Ga) and again during the Ottawan. Seven zircon samples from the 1.15 Ga Morin anorthosite suite were dated to confirm earlier age determinations, and Ottawan metamorphic rims (1.08–1.07 Ga) were observed in two samples. U-Pb dating of titanite in nine marble samples surrounding the Morin anorthosite suite yielded mixed ages spanning between the Shawinigan and Ottawan metamorphisms (n=7), and predominantly Ottawan ages (n=2). Our results show that Ottawan zircon growth and resetting of titanite ages is spatially heterogeneous in the Morin terrane. Ages with a predominantly Ottawan signature are recognized in the Morin shear zone, which deforms the eastern lobe of the anorthosite, in an overprinted skarn zone on the western side of the massif, and in the Labelle shear zone that marks its western boundary. In the rest of the Morin terrane titanite with Shawinigan ages appear to have been only partially reset during the Ottawan. Further work is needed to better understand the relationship between the character of Ottawan metamorphism and resetting in different parts of the Morin terrane.

The Role of Mosque to Avoid Violent Extremism: A Comparative Study of Eastern and Western Countries

The present project aims to conduct a comparative study between Eastern and Western countries on the role of mosques to avoid violent extremism in society analyzing their functioning. The purposes of the study are to explore the link between mosques and extremism and to draw a policy outline to avoid violent extremism. This is a qualitative study including formal and informal interviews, observations, and secondary data. Theoretically, the concept of Avoid Violent Extremism has been described in the light of a theory, Iannaccone and Berman’s (2006) Religious Extremism, and traced the relevant situation in the Pakistani context. Lahore, Karachi, Peshawar, and Quetta are the target cities from the Eastern side while Ottawa, New York, Paris, and London are from the Western side. This study reveals that sectarianism is deeply rooted in Pakistani mosques, variety in internal control systems, and lack of administerial regulations. In Western countries, there is scope for the training of Imams with the administerial checks on the performance of mosques and Imams, and promoting nationalism. This project outlines a Nation Action Plan to incorporate the role of mosques in the welfare of the country and to avoid violent extremism and promote community resilience.

Expansion of a localized population of the introduced Stratiotes aloides (Hydrocharitaceae) in Lough Derg, Ireland

An expansion of an introduced female clone of Stratiotes aloides L. (Water-soldier) was located in a delta region on the western side of Lough Derg, Co Galway (v.c.H15), Ireland in 2007. This population was followed over a thirteen-year period. It was initially located at three adjacent sheltered localities, within sweepback bays on either side of an emerging river and within an adjacent canal. The study involved surface observations later supplemented with aerial images. The shallow water conditions, shelter and the presence of Phragmites australis appear to have supported the early establishment by retaining small S. aloides clusters amongst its stems. These clusters later merged to produce a mainly surface expanding monoculture. This enlarged from less than 1 ha to approximately 3.3 ha to occupy much of the sheltered Rossmore Bay area during this study. Flowers were first noticed in 2008, and during subsequent visits, producing infertile seed-pods. Expansion took place with the production of daughter plants. A small nearby population, 1 km to the east, within an unused harbour, did not produce an emergent phase. A small group in a shallow cut, between the two locations, disappeared during the study. Aerial images from different sources were useful to identify the expansion of the emergent stage due to the distinctive bright green coloration of surface leaves. It is unclear how this plant arrived in Lough Derg, but might have been a garden plant release. Small drifting plants, seen during wintertime, may yet colonize other regions within this lake.

Novel U-Pb isotopic zircon data on the rhyolite of the Saf’yanovskoe Cu-Zn deposit (Middle Urals)

Research subject. Zircons from the Saf’yanovskoe Cu-Zn deposit rhyolite (Middle Urals). For the first time, zircon U-Pb dating for the rhyolite of the ore-bearing volcanic-sedimentary rocks of the Saf’yanovskoe deposit was performed. The volcanites are characterized by an andesite-rhyodacite composition and are localized at the southern edge of the Rezhevskaya structural-formation zone (SFZ) of the Eastern Ural megazone. A number of publications assign these rocks either to the basalt-rhyolite formation of the Middle Devonian, or to the basalt-andesite-dacite-rhyolite formation of the Lower-Middle Devonian.Aim. To estimate the age of the ore-bearing volcanic rocks under study using the U-Pb SHRIMP-II isotop ic system of zircon from the rhyolite of the eastern side of the Saf’yanovskoe deposit. By its chemical composition, the rhyolite belongs to the silicic varieties of subvolcanic rocks. Methods and results. The U-Pb isotopic system of zircon was studied by 5-collector mass-spectrometer of high precision and emission of the secondary ions SHRIMP-II (ASI, Australia) in the VSЕGEI Institute. U-Pb relations were investigated by a procedure developed by I.S. Williams. The U-Pb data obtained based on 13 zircon grains showed the age of 422.8 ± 3.7 Ma. Conclusions. The U-Pb dating of zircon obtained previously from the lens-shaped andesite bodies of the western side of the Safyanovskoe deposit gave the age of 422.8 Ma, which corresponds to the Przydoli series epoch of the Upper Silurian. We established that, among the volcanic rocks of the Saf’yanovskoe deposit, the effusive formations of the Upper Silurian are present.

Tenggar Cave, Tulungagung: preliminary study and its paleontological potentials

Goa Tenggar or Tenggar Cave is situated in the karstic physiography of southern Tulungagung, East Java that made up of prehistoric caves. These include the Wajak complex (minimum age of 37.4 to 28.5 thousand years ago) and the Song Gentong (around 7000 BP). The formation of Tenggar Cave is influenced by the subterranean river that penetrates the limestone unit. This cave has a front width of ± 10 m and a roof height of ± 8 m. The east side of the cave floor is a layer of soil, and the western side is the river. The inside of the cave composed by very compact conglomerate deposits and paleosoil that contains faunal remains, including Cervus sp., Bos sp., Bubalus sp., and Bibos sp., which may have occurred during the Pleistocene. The fossilized faunal remains from Tenggar Cave show that there was a relatively open environment during that time, such as a savannah with large trees and flowing rivers around the cave. The paleoenvironment indicates late Pleistocene to early Holocene period, similar to paleoenvironment in the Sewu Mountains that stretch along the southern part Java from central to the eastern tip of the island includes the coastal towns of Gunung Kidul, Pacitan and Tulungagung. The situation is certainly a point of interest when associating the findings with the surrounding sites, starting from Wajak, Song Gentong, Pacitan, Ponorogo, and Gunung Kidul. However, absolute dating test is necessary to be more certain of the lifetime of the fossilized fauna. If the fossils were from the Late Pleistocene, it could be an important information for the fields of paleontology, paleoanthropology, and prehistoric archaeology given that the occurrence of sites with such antiquity are limited in Southeast Asia. It is essential to conduct intensive research in Tenggar Cave in the future.

The spectre of the thing: The construction of the Sydney Gay and Lesbian Holocaust memorial

The Sydney Gay and Lesbian Holocaust Memorial is situated on the western side of Green Park in Darlinghurst, in Sydney, Australia. Darlinghurst is considered the heart of Sydney's gay and lesbian population, having been the site of demonstrations, public meetings, Gay Fair Days, and the starting point for the AIDS Memorial Candlelight Rally. It is also very close to both the Sydney Jewish Museum and the Jewish War Memorial. The planning and construction of the Memorial between 1991 and 2001 was a process framed by two competing imperatives. Balancing the commemoration of a subset of victims of the Holocaust with a positioning of the event as a universal symbol of the continuing persecution of gays and lesbians was a challenge that came to define the ten year struggle to have the memorial built.

By Canoe and Speedboat: The Recent Expansion of the Ìlàjẹ Fishing Trade

Competition has remained a significant feature of trade, particularly in regions with diverse social groups like the Niger Delta region of Nigeria. This article examines the expansion of trade among the Ìlàjẹ communities of Ondo State in the coastal area of Yorùbáland, which to the best of our knowledge has not been documented. Historical method of data collection and analysis were employed in the study. These include primary and secondary sources. The primary sources are mainly comprised of interviews of key informants and participants’ observations. The secondary sources consist of journal articles and texts. The results were analyzed qualitatively. The growth in coastal trade in the Ìlàjẹ area from 2010 onwards was largely due to the construction of new roads along the coast, which linked Ìlàjẹ to the wider road network. Between 2009 and 2013, new trading routes emerged along the road from Igbokoda to Araromi via Atijere on the western side to Ògun and Lagos state, passing through towns like Ipárè, Oko-Ńlá, Obinehin, Etíkàn, Erékè, and Àbòtó. Another route linked Igbokoda with Òde-Ùgbò and Ùgbò-Ńlá coastal market in the east. As traders and goods came into Ìlàjẹ from various parts of Nigeria, new markets sprang up to facilitate the exchange of upland goods for fish products. The construction of new roads also encouraged social and economic development by bringing into the area goods and commodities hitherto not transportable on water, such as ‘modern’ building materials. However, far from reducing water-based activity, the overall increase in trade has also contributed to an increase of water-based traffic, especially for fishing.

The Role of New-Emerging Lands on Sources of Aeolian Sand Deposits Driven by Shrinking of the Urmia Salt Lake

Urmia Lake, the largest saline lake in Iran and the Middle East, is located in the northwest of Iran, has shrunk over the past decades. The reduced water level has increased the area of dry land around the lake allowing new environmental hazard such as sand dunes encroachment, particularly on the western side of the lake. There are five terrain types that could contribute sediment to the dunes, and it is the main aim of this research to identify the contributions to the dunes of each terrain type. Fifteen surface samples were collected from the five most erodible terrain types and eight samples were collected from the dunes both in downwind and upwind directions from the lake, and major element components were measured using X-ray fluorescence (XRF). According to the Besler classification, all samples are in the saline class. Also, the chemical index of alteration (CIA) values in all samples were less than 50, indicating weak weathering. Based on multivariate statistical analysis, suitable tracers were selected and were imported to the sourcing equations. Quantification of uncertainty and the creation of two new fingerprinting models for aeolian sediments based on both Bayesian and GLUE procedures were used. The highest proportion comes from the salty and puffy lands (44.2%) followed by salty polygon land (23.5%), clay-salty areas, puffy-flaky lands (7.01%), the terminus of the fine sandy alluvial fan (13.2%), and clay-salty abandoned lands (12.1%). It is concluded that if land managers use these results, they can more efficiently decrease the hazards posed by dune reactivation and migration though implementation of soil conservation on the affected lands around the dried lake.
