Local abundance of hippuritids in radiolitid dominating Adriatic-Dinaridic carbonate platform domain: Coniacian reef-like lithosome at Čitluk (SW Bosnia and Herzegovina)
The region of western Herzegovina is characterized by past mining activities in abundant bauxite deposits. The activities revealed the topmost parts of the Upper Cretaceous succession in the High Karst tectonic unit of the Adriatic-Dinaridic carbonate platform (ADCP) domain, which is characterized by longlasting hiatus at the unconformity between „Early Senonian“ and Eocene shallow-water carbonates. Topmost part of the Creteceous succession is recrystalized and karstified during the long lasting Late Cretaceous to Eocene regional subaerial exposure. Weathering processed after bauxite removement contributed to recognition of many rudist lithosomes within these bauxite mines (http://hercegovina-geoarheo.blogspot.com/). Detail fieldwork in one of these outcrops near Čitluk, allow us to determine many of in situ inspected and collected rudist valves, as well as to recognize general depositional pattern of the lithosome. Although the valves and the host limestone are rather recrystalized, we find out that most of them belong to the Hippuritidae familly. We find it interesting for research, since both open-platform and platform-top deposits in the whole ADCP domain is characterized by predominance of radiolitids. A reef-like appearance of the outcrop is obviously related to a morphology of the unconformity, that is a consequence of palaeokarstification and selective erosion during the Late Cretaceous to Eocene exposure.
