Organic matter preliminary study of Paleogene sediments of the Subsilesian Unit an its source pottential for hydrocarbons

Vol.20,No.1-2(2013)

Abstract
The subject of the present paper is the analysis of the source rock potential of the Paleogene formations in the outer Western Carpathians. In the study area there are deposits rich in organic carbon material (4–11 % TOC), mostly dark coloured claystones and siltstones, which were deposited in the anoxic conditions. Source rocks character of the sediments was studied on the basis of structure of organic material and degree of their transformation. Kerogen of type III (terrestrial type) predominates in the studied samples. Degree of thermal transformation is low and corresponds to the beginning or middle part of the oil window.
