Paleoproterozoic intracratonic compression across the Slave Province resulted in eastward indentation of the wedge-shaped Slave craton into the Thelon orogen. Indentation was accommodated by shortening and crustal thickening at the apex of the Slave wedge, bounded to the south by the right-lateral McDonald fault and to the north by the left-lateral Bathurst fault. The Paleoproterozoic, nonmarine Et-Then Group in the East Arm of Great Slave Lake records the history of this indentation. The Et-Then Group consists of two formations. The older Murky Formation is an alluvial-fan conglomerate deposited unconformably over older Paleoproterozoic sedimentary and igneous rocks and Archean metamorphic and igneous rocks. Clast composition indicates that the Murky Formation was derived from these older rocks, eroded during initial translation and uplift on the McDonald fault system. The younger Preble Formation conformably overlies the Murky Formation and is a braided fluvial sandstone. The modal framework composition indicates a granitoid source. On the basis of west-southwest paleocurrrents, modal composition, and depositional style, the Preble Formation is interpreted to be derived from the apex of the Slave wedge. Isostatic uplift at the apex of the Slave craton, due to crustal thickening, provided sufficient amounts of sediment to effectively bury local relief in the East Arm and change the depositional style from one of locally derived alluvial fans (Murky style) to a westward-sloping, regionally extensive braid plain (Preble style).

Emigration has been known to mankind for more than a century. We name the factors contributing to emigration, give examples from the history of emigration both abroad and Russia. We emphasize that at the present time, Russian citizens emigrate to other countries, using the right to freely leave the state, and can also have dual citizenship under Russian law, or renounce citizenship, and then get it again. We pay special attention to the settlement of the territory of North Caucasus, which began in the 8th – 7th – 6th – 5th thousand BC. We analyze the features of emigration of people from North Caucasus after the October Revolution of 1917. The specifics of the emigration of people from this region of country are emphasized. Thus, the majority of people emigrated to the Ottoman Empire, and then moved to Europe. We indicate that in fact, after the adoption of the Decrees of the Central Executive Committee, the SNK of RSFSR in 1921, “On the deprivation of the rights of citizenship of certain categories of persons who are abroad” many emigrants from Russia, including North Caucasians, have become disenfranchised. This circumstance greatly influenced the publication of the Nansen passport (it was introduced in 1922 and became widespread in 1924), according to which emigrants were granted a number of legal and social rights. In addition, it is applicable to emigrants from Russia, including from the North Caucasus, in 1922 and 1926. The Geneva definition of “Russian refugee” was given, and the International Convention on the International Status of Refugees of 1933 created an alternative to naturalization for refugees from Russia. Subsequently, before the outbreak of the Second World War, people received, as a rule, the citizenship of the countries in which they began to live.

The Mesoproterozoic 1108–1105 Ma Osler Group, a 3 km thick succession of basaltic flows and sedimentary units on the north shore of Lake Superior, is among the oldest expressions of the Midcontinent Rift. Basal sediments of the Simpson Island Formation (new name) deposited by braided fluvial systems record westward transport of debris eroded from local Archean and Proterozoic rock units. Strata deposited by this fluvial system are intercalated with, and overlain by, ocean-island basalt (OIB)-like basalts, which become increasingly contaminated up section (εNd(1100Ma) = +0.3 to –5.3). The light rare-earth element (LREE) enriched (La/Smn = 1.5–3.9) and heavy REE (HREE) fractionated (Gd/Ybn = 1.5–3.7) subaerial flows are divisible into two units that correlate with other sections of the Osler Group to the east, but simple correlations with more distant sequences are difficult. The volcanic rock dominated portion of the succession is overlain by a thin (25 m thick) conglomerate–sandstone assemblage representing southeast progradation of an alluvial fan in a semi-arid climatic setting. Clast lithologies and geochemistry indicate no extra-rift detritus was delivered from the hinterland of the fan. Various lines of evidence in both volcanic and sedimentary rocks support a scenario where early, pre-1108 Ma, subsidence along a north–south axis from the western arm of the rift to the Nipigon Embayment was replaced by subsidence along the east–west rift axis between 1108 and 1105 Ma.

There were signs of the first civilization known to humanity for more than 6000 years BC in the north of Iraq have disappeared this civilization to appear after 500 years in southern Iraq, the Sumerian civilization, which was considered as the opinion of scientists or civilizations, exceeds the impact to Asia and the countries that had been in contact (Sumerians) and see them today in other towns and villages. In subsequent periods of time appeared distinct personalities to their nature, religious, social, special clothing with clothes seem especially long. And usually dress is made from raw wool material making them in the Sumerian era. Put the garment on the body and leaves the top of the right shoulder with the survival of an open hand. There are of special clothing used by the clergy in the exercise of religious mourning rituals .There are traditional clothes to the clergy of other faiths. The clothing we see in the beginning of the third millennium BC has gained status in society in general, and was also the head cover. The animals have for centuries symbolized the signs of a divinity that we see hanging on the walls of some temples in northern Iraq. Centuries have been mentioned in the history of the Arabian were animal horns in Sumerian times to symbolize the moon in the Sumerian language .

The Late Jurassic - Early Cretaceous tectonic evolution of SE Siberia was marked by the closure of the Mongol-Okhotsk ocean. While this geodynamic event led to compressive deformation and denudation in a wide area encompassing the North-Altay, Sayan and Baikal Patom ranges, it was contemporaneous to widespread extension from the Transbaikal region situated immediately north of the suture zone to the Pacific plate, affecting eastern Mongolia and northeastern China. In this study we review the paleontological and sedimentological data available in the Russian literature and provide new macro-floral and palynological data from the Mesozoic sediments of three Transbaikal basins. These data are used to describe the paleoenvironmental and paleoclimatic evolution of the Transbaikal area in order to assess the topographic evolution of the region in relation with the closure of the Mongol-Okhotsk ocean. We establish that the Transbaikal basins evolved in a continuously extensional tectonic setting from at least the Early-Middle Jurassic to the Early Cretaceous. The associated sedimentary environments are characterized by retrogradation from alluvial fan–braided river dominated systems prevailing during the Early to Middle Jurassic initial opening of the basins to meandering river– lacustrine systems that developed during the Late Jurassic - Early Cretaceous interval. No evidence of high relief topography was found and we conclude that, while compression and denudation occurred in the North Altai, Sayan and Patom ranges, in the Transbaikal region, the docking of the Mongolia-North China continent to Siberia was a “soft collision” event, possibly involving a major strike-slip displacement that did not lead to an orogenic event implying strong compressive deformation, crustal thickening and topography building.

The article is devoted to the military action of the Roman Empire in the Middle-Danube valley in the early spring 170 year 2-nd centuries A.D. The main aim of this article consists in reconstruction one of the important events in Roman wars against the Germans tribe marcomanni, who lived on the territory of modern-day Czechia (ancient Boygemia). The author uses the analytical and comparative methods, analyzing the historical works of Roman authors and epigraphic facts. One of the main new aspects of article consists in chronology of events. The author tries to prove that defeat of Roman army and death of praefectus Marc Macrinius Vindex took place at the same time in early spring 170 year 2-nd centuries A.D.. This defeat had the important influence on the other military operations in the next time. Marcomanni and his allies seriously threatened the Roman province of Pannonia situated on the right bank of the Danube. The emperor Marcus Aurelius (161 — 180 A.D) waged several wars against the marcomanni and their allies quadi in 167 — 180 A.D. In winter 169 A.D. Marcus Aurelius became the sole emperor. He came back in Carnuntum in Upper Pannonia and began to complete the army for the offensive against marcomanni. The legatus Augusti Marc Macrinius Avitus Catonius Vindex with vexillationes of five Pannonia's legions and a few auxiliums forced a crossing the Danube in the early spring 170 A.D. Marcomanni defeated the Roman army and killed the legatus Augusti. The Germans captivated many soldiers from legions and auxiliums, burned several war-camps in Upper and Lower Pannonias. They reached the borders of the North Italy and besieged the Aquileja again. The author comes to the conclusion, that in result of the defeat of Marc Macrinius Vindex the Roman troops in the Middle and Lower Danube stood on the defensive.

ABSTRACT Recent fieldwork and the synthesis and reappraisal of aeromagnetic, geologic, structural, geochemical, and geochronologic data have provided a new perspective on the structural evolution and geologic history of the Arabian Shield. Although Paleoproterozoic rocks are present in the eastern part of the Shield, its geologic evolution was mainly concentrated in the period from 900 to 550 Ma during which the formation, amalgamation, and final Pan-African cratonization of several tectonostratigraphic terranes took place. The terranes are separated by major NW-trending faults and by N-, NW- and NE-oriented suture zones lined by serpentinized ultramafic rocks (ophiolites). Terrane analysis using the lithostratigraphy and geochronology of suture zones, fault zones, overlapping basins, and stitching plutons, has helped to constrain the geologic history of the Arabian Shield. Ophiolites and volcanic-arcs have been dated at between 900 and 680 Ma, with the southern terrane of Asir being older than the Midyan terrane in the north and the Ar Rayn terrane in the east. Final cratonization of the terranes between 680 and 610 Ma induced a network of anastomosing, strike-slip faults consisting of the N-trending Nabitah belt, the major NW-striking left-lateral transpressive faults (early Najd faults), lined by gneiss domes and associated with sedimentary basins, and N- to NE-trending right-lateral transpressive faults. Following the Pan-African cratonization, widespread alkaline granitization was contemporaneous with the deposition of the Jibalah volcanic and sedimentary rocks in transtensional pull-apart basins. Crustal thinning was governed by the Najd fault system of left-lateral transform faults that controlled the formation of the Jibalah basins and was synchronous with the emplacement of major E- to NW-trending dike swarms throughout the Arabian Shield. The extensional episode ended with a marine transgression in which carbonates were deposited in the Jibalah basins. Continuation of the thinning process may explain the subsequent deposition of the marine formations of the lower Paleozoic cover. Our interpretation of the distribution and chronology of orogenic zones does not correspond entirely to those proposed in earlier studies. In particular, the N-trending Nabitah and NW-trending Najd fault zones are shown to be part of the same history of oblique transpressional accretion rather than being two distinct events related to accretion and dispersion of the terranes.

AbstractThe geographical distribution of the Ananatuba phase has been extended to the eastern coast of Marajó by the discovery of J-26: Castanheira on the right bank of the middle Rio Camará. Two stratigraphic cuts were excavated, and the pottery obtained was classified into the types established by Meggers and Evans (1957). The resulting seriated sequence shows trends of ceramic change parallel to theirs and a similar intrusion of Mangueiras phase sherds in the upper levels of the deposit. Interdigitation of the J-26 levels into the seriated sequence for the Ananatuba phase shows the new site to occupy a relatively late position, supporting the earlier inference of expansion from the north coast toward the southeast during the history of the phase. A charcoal sample obtained from Cut 1, Level 40-50 cm., and correlating with the appearance of Mangueiras phase sherds in the refuse, gave the date of 980 B.C. ± 200 (SI-385), which places the initial occupation of Marajó by pottery-making groups within the Formative period.

The Hunter Fault System or "Lineament" separates the Permian and Triassic of Sydney Basin in New South Wales from the relatively complicated region to the north and east with exposed Carboniferous and older rocks and an increasing amount of identified Permian. David in his inimitable fashion grasped the essentials in 1907. He noted that the fold movements began towards the end of the Upper Permian with an important phase between the Upper Coal Measures and the Narrabeen Series. He also noted the main north-south component. The interest kindled by David was reflected in the work of Browne, Carey, Osborne, Raggatt, and Voisey. These workers established that the Carboniferous was affected by tectonic movement prior to the Permian and that the main ("orogenic") folding of the Permian/Triassic began with deposition of the Muree Formation and continued during the Upper Permian with overthrusting at the end of the Permian followed by strong rotational stress. This entire episode was called the Hunter-Bowen Movement by Carey and Browne in 1938. They also noted that the area of the subsequently developed Sydney Basin supplied sediment in the Carboniferous to the north and east. Raggatt, in his unpublished thesis of 1938 had already concluded that increasing compression led to upthrusting and eventually to torsion. Much of this seems to have been lost sight of in recent work. Current work confirms that the Permian/Triassic folding began with the Muree and that prior to this in the Permian a northwest to southeast graben was present to the south and west of the Hunter structure. Prior to the Permian the area of the Sydney Basin supplied detritus in the Carboniferous north and east of the Hunter structure apparently indicating a long-lived structure or lineament on which a reversal of movement took place.
