Litostratygrafia najniższego kimerydu okolic Sulejowa nad Pilicą
Abstract
LITOSTRATIGRAPHY OT THE LAWERMOST KIMMERIDGIAN FROM THE AREA OF SULEJÓW UPON PILICA
Summary
The Upper Jurassic deposits recently assigned to the Upper Oxfordian and Lower Kimmeridgian (the Idoceras planula - Katroliceras divisum ammonite zones) occur in the area of Sulejów upon Pilica river, NW Mesozoic margins of the Holy Cross Mts. The deposits area here divided into 4 lithological complexes. The section of the second complex comprising the Sutneria platynota and possibly the basal part of the Ataxioceras hypselocyclum zone is discussed in detail. This complex primarily comprises sparry microonkolitic, lumpy and micritic limestones. The limestones yield numerous solenoporids, corals, pelecypods and gastropods. Deposits of that complex correspond to the Recent deposits of the lumpy, lumpy-silty and partly silty facies from the Great Bahama Bank.
