Peat sediments represent important environmental and climatic archives, as well as recording information on the processes affecting the formation of these deposits; combined these data can be used for paleoreconstruction of peat-bogs. In this paper we characterize heavy mineral-rich sandy layers from two peat-bog sites in Mizerów and Strumień (Poland). In both cases, the most common identified mineral suite is: epidote, staurolite, tourmaline (dravite and schörl), garnet, spinel, Al2SiO5 polymorphs (sillimanite, kyanite, andalusite), amphibole (mainly hornblende), pyroxene (e.g., richterite, diopside), perovskite, topaz, cordierite, apatite, monazite, chromite, ilmenite, chlorite, iron oxides, rutile and siderite. This mineral suite is characteristic of a metamorphic aureole surrounding a magmatic body. Pyrite is likely authigenic in origin. Apatite and monazite were employed for U-Pb and CHIME dating, respectively. Based on the U-Pb age information composition and textural features of selected minerals, different provenance areas were indicated: the Tatra Massif, the Bohemian Massif, and the Silesian Basin area. Transport of the investigated mineral phases was linked to development of both the Odra (praOdra) and the Vistula valleys.

Abstakt “Chocolate’”flint was the main raw material used by the Early Neolithic Linear Band Cul¬ture (LBK) groups in the Polish Lowlands. Since the second (note) phase of the development of this culture, the early farmers developed a complex system of distribution of ‘chocolate’ flint within the great-valleys zone of the Lowlands. Concretions of raw flint were transported by the Vistula river from the outcrops located on the southeastern slopes of the Świętokrzyskie (Holy Cross) Mountains to Kuyavia. They were worked into cores and processed in settlements close to the Vistula valley. Cores and blades/flakes were also exported to distant locations to the west as far as the Lower Oder basin area. One would expect the existence of specialised workshops providing materials for such a mass distribution. Kruszyn site 13, Włocławek distr., is the first LBK ‘chocolate’ flint workshop discovered close to the Vistula river concentrated on production of blades. This site fits well into the LBK flint distribution system developed on the Lowlands

The metal content was determined using the WD-XRF method in the peat from the Wąpiersk bog and the Las Nadwelski bog (Welski Landscape Park, Poland). The results of the study show that the concentration of metals, especially heavy metals in peat bogs in Welski Landscape Park is low in general. In both bogs, the concentration of heavy metals was lower in the center than on the border. This shows that heavy metals are absorbed by the peat at the border and their further migration is limited. There are more elements such as iron, calcium and magnesium in the Las Nadwelski bog. There is more light on the border of the forest, which also plays an important role in decomposing plant debris, releasing metals. Heavy metals content was higher in Wąpiersk bog – a bog with higher anthropopressure. To sum up, the peat bog actively captures heavy metals, immobilizing them, and acts as a kind of “filter”. Peat is a good agent for retrospective monitoring of metals migration and accumulation in the environment.

ABSTRACT Mexico is an attractive place for provenance studies focused on reconstructing the tectonic evolution of North America. This is because Mexico hosts a well-preserved clastic record associated with some of the major Mesozoic and Cenozoic tectonic processes that shaped the face of this continent. However, the available information on Mexican pre-Mesozoic source terranes is presently insufficient for provenance analysis. With the aim of drawing the guidelines for provenance determination, we present here detrital modes, geochemical data, and zircon U-Pb ages for detritus derived from pre-Jurassic basement complexes of Mexico. Our data show that the various basement complexes produce distinctive detrital modes and supply diagnostic and compositionally different detrital heavy minerals that represent powerful provenance tracers. The Oaxacan Complex, Ayú Complex, and East Mexico Arc are the main sources of quartzo-feldspathic and feldspatho-quartzose detritus. Quartz with rutile needles, mesoperthitic K-feldspar, orthopyroxene, augitic to diopsidic clinopyroxene, and Mg- to Ca-rich almandine (Alm71–52Grs7–3Prp43–23Sps3–1Alm74–56Grs21–19Prp23–2Sps5–2) are common minerals in detritus from the Oaxacan Complex. The Ayú Complex supplies detritus marked by the occurrence of sagenitic biotite and white mica, as well as Mn-rich almandine (Alm69–66Grs4–3Prp18–11Sps19–10). Detritus from the East Mexico Arc contains any of these mineral phases ubiquitous in the Oaxacan and Ayú complexes. The Acatlán Complex is the main source of detritus dominated by metamorphic lithic grains and quartz, with minor amounts of feldspar. Lithic grains are rank 2–4 metabasitic, metapelitic, and metapsammitic–metafelsitic fragments. Diagnostic mineral phases are schorl–dravitic tourmaline, Na-amphibole, and helycitic garnet varying from a Ca- to Mn-rich almandine (Alm74–55Grs34–15Prp16–3Sps12–1-Alm70–46Grs20–15Prp3–1Sps32–12). Zircon U-Pb geochronology proves to have some virtues but also major limitations because: 1) the zircon U-Pb age signature of many different sources in Mexico is similar and 2) zircon documents a limited number of sources because of variations in zircon fertility.

Transformation of Lake Ecosystem into Peat Bog and Vegetation History Based on Durne Bagno Mire (Lublin Polesie, E Poland)In this paper, the history of Durne Bagno, i.e. the largest peat bog in the Lublin Polesie, is shown. Peat bogs are a unique element of the Polesie landscape. They occur mostly in the subregion of the Łęczna-Włodawa Lake District occupying 1.07% of its area. They fill basin-shaped depressions without outflow, often in the immediate vicinity of dystrophic lakes. Based on interdisciplinary research, the changes of vegetation cover and the Durne Bagno lake-mire ecosystem in the Late Glacial and Holocene are presented. The environmental conditions are reconstructed from pollen analysis, detailed identification of algae ofPediastrumgenus and chemical composition of deposits, together with the results of Cladocera analysis. The distribution of archaeological artefacts in the surroundings of Durne Bagno peat bog gives the view on the intensity of settlement in this area. The duration of the limnic and mire stages during the development of the ecosystem was different in different parts of the examined depression. In its central part the limnic stage lasted about 8000 years and included the period from the Late Glacial to the middle Holocene (to about 6000 BP). It is represented by 7 pollen zones and 6 chemical zones. The mire stage contained a part the Atlantic period and on the Subboreal and Subatlantic periods. It is represented by 4 pollen zones and 5 chemical zones. Limnic and mire deposits differ widely in the concentrations of chemical elements. The contents of mineral material and almost all analyzed elements in limnic deposits are high. These deposits are characterized by positive correlation between the contents of Zn and Cr and the frequency of Cladocera fauna. Peat contains very low amount of mineral material. The contents of Ca, Sr and Ba are rather high in sedgemoss peat. The concentrations of these elements decrease upwards due to oligotrophic processes and sedentation of sedge-Eriophorum-Sphagnumpeat. Peat succession was modified by pastoral economy of prehistoric man.

We used moss increment counting to obtain well-defined samples of the topmost peat layers of two Sphagnum fuscum hummocks. The two ombrotrophic bogs, Lakkasuo in central Finland and Korvinsuo in eastern Finland, are of different ages, covering 3 and 9 ka, respectively. Using AMS dating, we traced bomb-produced 14C through the topmost parts of the two peat profiles. A well-defined 14C activity peak was found in both sequences dating the corresponding layer to ad 1965. A comparison between the maximum peat activities and the corresponding atmospheric values for the period of interest provides an opportunity to evaluate the amount of CO2 emanating from the decaying peat bog, and taken up by the living sphagnum plants.Considerable variations in δ13C values were also observed. These variations indicate, at least partly, annual variations in the emission rate of CO2 from decomposition of older peat in the bog, and are connected with climatic factors such as temperature and precipitation.

Mineral Assemblages

Two main source areas of heavy minerals in tills have been defined in the Great Lakes region: a source in the Superior and Southern Provinces and another in the Grenville Province. The Superior–Southern source is typified by low heavy mineral content and high epidote percentage in contrast to the Grenville source which has a high content of heavy minerals of which garnet, tremolite, and to a lesser extent sphene and orthopyroxene are characteristic. The Huron lobe tills have a mineral suite characteristic of the Superior–Southern source. Two subsources can be distinguished in the Superior–Southern area; however, they are too limited in extent to be characteristic of major glacial lobes. Two other subsources have been identified in the Grenville provenance area: a western Grenville subsource containing abundant garnet and having a low purple–red garnet ratio; and an eastern Grenville subsource distinguished by high garnet and tremolite content and a garnet ratio generally greater than one. The western and eastern Grenville subsources are the provenance areas for the tills of the Georgian Bay lobe and the Ontario–Erie lobe respectively. A possible third Grenville subsource in the Adirondack Mountains is distinguished from other Grenville sources by a lower heavy mineral content and more abundant orthopyroxene and magnetic minerals. This assemblage may be characteristic of the southern portion of the Ontario–Erie lobe.

The quartz sand of the Lower Cretaceous Robbedale Formation and lowermost part of the Jydegard Formation in the Arnager-Sose fault block of Bornholm has been investigated with respect to mineralogy, grain-size, grain rounding and grain shape. Analyses of both light and heavy minerals have been carried out for 18 samples from different localities and facies. The purpose of the investigation was to try to recognize the possible types of source rocks and provenance areas. The Precambrian basement rocks of Bornholm are not the main sources of the sand, especially not the heavy minerals, but parts of the sand may have originated from the basement. The Palaeozoic sandstones and siltstones have delivered only a small amount of material. Parts of the older Mesozoic sediments of the Bornholm Group and Homandshald Member may have been redeposited in the Lower Cretaceous as they contain the same kinds of heavy minerals as the Robbedale and Jydegard Formations, although in differing amounts. It seems very possible, however, that most of the Mesozoic sediments of Bornholm have had a source area outside Bornholm, and this source area has been nearly the same during the whole span of time. The Fenno-Scandian Shield seems to be the most obvious provenance area, but eastern and southern areas are possibilities too. It is concluded that most of the Lower Cretaceous sands are first deposition cycle sediments of both local and distant origin combined with minor amounts of polycyclic sediments of mainly local origin.

The presence of iron oxides may provide a sensitive indicator of the effects of cropping practices on coffee plantations. Authors characterized the mineral phases present in soil A horizons at three different farms located in the Department of Tolima within the regions of Líbano and Villahermosa. Our analysis includes X-ray diffraction, Mössbauer spectroscopy, and remote sensing to discriminate the distribution of the different magnetic mineral phases. X-ray diffraction was used to identify the mineralogical properties of iron oxide such as hematite, goethite, and ferrihydrite (Fh), as well as tectosilicate minerals such as albite and sanidine. Mössbauer spectroscopy results for samples taken at room temperature indicate the presence of Fe2+ and Fe3+ mineral phases, which possibly correspond to ilmenite or magnetite. Finally, Sentinel-2A multi-spectral imager (MSI) data was used to map the distribution of iron oxides and study the influence of their distribution throughout the study area. A high correlation between Mössbauer spectroscopy and Sentinel-2A MSI data exists throughout the study area. The results suggest that farms close to the main Nevado del Ruíz Volcano have a more significant mineralogical variability. In contrast, more distant farms are characterized by soils with more iron oxides, the product of weathering, erosion, and human activities.

Plutonic Rocks

Five particular occurrences of layered plutonic rocks within the south Greenland alkaline province are discussed. These five examples are of gabbro, anorthosite, syenite of larvikite-nordmarkite type, foyaite and eudialyte nepheline syenite, respectively. Each is thought to consist of cumulate rocks formed by bottom accumulation of the early mineral phases and the subsequent crystallization of the trapped interstitial liquid. The possible causes of banding and feldspar lamination are considered in each case. The presence or absence of feldspar lamination is used as one criterion for deciding whether the settling of the early (cumulus) phases occurred through moving or still magma. Magmatic flow during the accumulation of the cumulus mush was important in controlling the degree of packing within the latter and hence was influential in determining the ultimate bulk composition of the solidified rock.

In a period with frequently occurring hydrological extremes, research on areas with a high retention potential is brought into focus. The Šumava Mountains peat bogs are important parts of the landscape in the headwater area of the Otava river basin. The study objective is to describe the variability of discharges and the dynamics of groundwater level changes in various types of peat bogs, and to identify connections between observed physico-chemical water properties. This is assessed by basic statistical methods. The rainfall-runoff process and physico-chemical water properties can be affected by many factors. In this case, strong relations between the observed parameters were identified along with considerable differences in the involvement of various types of peat bog sites in the runoff process. It is evident that the peat bog pattern and its vegetation cover have an essential effect on the hydrological regime and water properties stored in a peat bog.
