The Kirchbach Formation consists of shale with lenses of carbonate nodules and argillaceous limestone composed of 3 to 10 cm thick layers of carbonate nodules (mudstone to wackestone) separated by thin argillaceous seams. The nodules reach a maximum size of 30-40 cm diameter. Some nodules can be classified as polymict breccia ranging from fine-grained packstone and wackestone to float- and rudstone, including bioclasts, normal ooids, peloids and carbonate intra- and extraclasts. The organic remains are dominated by fragments of crinoids and echinoids, cephalopods, bryozoans, small foraminifers, calcareous algae and microproblematica. In addition brachiopods, heterocorals, molluscs and trilobites occur. Conodonts are fairly abundant mainly in biomicrite and micritic intraclasts.

Abstract

The Kirchbach Formation consists of shale with lenses of carbonate nodules and argillaceous limestone composed of 3 to 10 cm thick layers of carbonate nodules (mudstone to wackestone) separated by thin argillaceous seams. The nodules reach a maximum size of 30-40 cm diameter. Some nodules can be classified as polymict breccia ranging from fine-grained packstone and wackestone to float- and rudstone, including bioclasts, normal ooids, peloids and carbonate intra- and extraclasts. The organic remains are dominated by fragments of crinoids and echinoids, cephalopods, bryozoans, small foraminifers, calcareous algae and microproblematica. In addition brachiopods, heterocorals, molluscs and trilobites occur. Conodonts are fairly abundant mainly in biomicrite and micritic intraclasts.
