| Abstract: | The sparitic Plassen Limestone (Tithonian, N.K.A., Upper Austria) The sparitic Plassen Limestone (Tithonian, N.K.A., Upper Austria) shows various types of calcite-fabric. We distinguish fibrous, fibrous-drusy, and drusy cavity fillings. While the fibrous fabric can be interpreted as submarine precipitation soon after sedimentation, an explanation of the drusy calcites as submarine or subaerial precipitation remains an open question. There are, however, indications of subaerial influences. For the origin of the dismicrites an interpretation as shrinkage structures may be considered. |
