Cave ooids in a Tertiary karst shaft at Pogorzyce, southern Poland

Abstract

The fossil cave ooids have first been reported from splash cups occurring in several horizons of alternating flowstone and sandy layers filling a Tertiary karst shaft at Pogorzyce, Cracow Upland. The study of the internal structure of the ooids shows the concentric laminae being primary, and the radial structure resulting from wet recrystallization.
