Beschreibung:
<jats:p>A formal lithostratigraphy of the Maastrichtian – Paleocene deposits in Krumovgrad district is worked out. Krumovgrad Group with two formations is distinguished: Šavar breccia Formation and Kandilka sandstone-conglomerate Formation. The formation of the rocks in the Krumovgrad Group in graben structures is a result of a collision compression coinciding in time with Laramian phase. The specific tectonic regime of the formation of those rocks predetermined the formation of a thick colluvial-prolluvial train, which consists of coarse-terrigenous and lake-marshy freshwater sediments. The newly obtained data allow to view in a different light the origin and development of the East Rhodope Paleogene Depression. Its beginning is considered to be in Maastrichtian – Paleocene, while it could be called East Rhodope Maastrichtian – Paleogene Depression.</jats:p>
