Litostratygrafia dolnego syluru w odsłonięciu Bardo Stawy (południowa część Gór Świętokrzyskich) — związek ze zmianami poziomu morza i cyrkulacją oceaniczną
Abstract
Lithostratigraphy of the Lower Silurian in Bardo Stawy (southern Holy Cross Mountains): relation to sea-level changes and oceanographic circulation.
S u m m a r y . The lower Llandovery black radiolarian cherts and shales of the Bardo Formation are interpreted as transgressive to highstand deposits produced by the marine flooding initiated in latest Ordovician time (persculptus graptolite zone). This formation was divided into the Rembów radiolarian chert Member and Zbrza shale Member. The sedimentary record of the Rembów Member was folded due to the late Caledonian tectonic activity. The accumulation of the radiolarian cherts was influenced by an upwelling system generated by the SE trade winds, which were active along the southern margin of the southern Holy Cross Mountains.
