Neogene coal-forming sedimentation in the Carpathian Foredeep, southern Poland

Abstract

Phytogenic sediments of the Carpathian Foredeep originated in close relationship to transgressive and regressive stages of the Badenian/Sarmatian marine cycle. Allocyclic mechanisms (sea level changes) mostly influenced phytogenic accumulation there. Phytogenic sedimentation was controlled by basement morphology. Brackish conditions, favourable for peat-forming vegetation, covered the valleys developed at the southern slope of the Holy Cross Mts. Therefore, caustobiolithes, occur mostly along the northern margin of the foredeep.
