Abstract The 2200 m thick Cretaceous units of well Gänserndorf UeT3 have been biostratigraphically analyzed based on cuttings from 3210 to 5140 m. deposits the Tirolic Glinzendorf Syncline (a part buried Northern Calcareous Alps) can be largely correlated with Lower Gosau Subgroup Grünbach Syncline. An exception is basal unit, which has no equivalent in This lower unit subdivided into a non-mar...
Abstract Understanding the local stratigraphy and geometry of sediment units is necessary for successful 3D modelling prediction ground behaviour engineering-geological properties urban land use construction. A detailed model main Rastaala basin in southern coastal Finland was constructed, combining a conceptual geological information from drill-hole logs geotechnical drilling. The based on cro...
The Cubito-Moura Unit is a high-P metamorphic succession that occurs in the southern part of Ossa-Morena Complex (SW Iberian Massif). It includes series metasedimentary, metafelsic and metamafic rocks affected by high-P, low to intermediate-T event during Late Devonian times. Geochemistry metabasic reveals generation protoliths occurred supra-subduction zone setting Ediacaran Early Ordovician t...
Radiocarbon-dated sediment cores from seven lakes and two bogs spanning the Cordillera de Mérida in the Venezuelan Andes were used to identify and date the regional history of late Pleistocene and Holocene glacial activity. Coring sites were selected at different elevations across a pronounced rain shadow from southeast (wet) to northwest (dry). Sediment lithostratigraphy and magnetic susceptib...
This paper discusses the lithostratigraphy of the Xinminbao Group in the Mazongshan area of Gansu Province, northwestern China, and the correlation of its biota. The Xinminbao Group was deposited in a fluviolacustrine setting in Mesozoic graben basins under a semi-arid, subtropical climate. The fossil sites concentrated in the lower part of the group have yielded dinosaurs, mammals and other ve...
