Native Selenium

Abstract Acicular crystals of native selenium up to 30 μm long occur together with barite on the surface of goethite partial pseudomorphs after millimeter-sized pseudotetragonal-prismatic pyrite crystals in calcite veins that cross-cut Senonian sandstones of the Silesian Nappe in the western Polish Outer Carpathians. Native selenium originated from selenium apparently released during bacteria-induced oxidation of pyrite at neutral or near-neutral pH conditions. Oxidizing bacteria preferentially colonized {100} faces of pyrite relative {111} faces.

The Cretaceous-Paleogene boundary in turbiditic deposits identified to the bed: a case study from the Skole Nappe (Outer Carpathians, southern Poland)The Cretaceous-Paleogene (K-T) boundary has been recognized in turbiditic sediments of the Ropianka Formation in the Skole Nappe (Bąkowiec section) on the basis of planktonic foraminiferids with an accuracy of 40 cm. Such precise determination of the K-T boundary for the first time in the Carpathians and in turbiditic flysch sediments in general was possible due to the successive occurrence of the Early Paleocene planktonic taxa of the P1 Zone above the latest MaastrichtianAbathomphalus mayaroensisZone with theRacemiguembelina fructicosaSubzone. The trends in composition of the latest Maastrichtian foraminiferal assemblages are similar to the Gaj section from the adjacent thrust sheet, probably due to the influence of the same paleoenvironmental factors.
