Middle Devonian limestone. Foliated, micritic, light pinkish grey, partly dolomitised limestone. Most strongly foliated layers are probably more argillaceous and represent bedding. Crinoid stem fragments and traces of burrows in foliated layers. On the east side of the quarry the foliation/bedding dip is about 10° SW. On the west side of the quarry upright folds about 1m in amplitude with a NS trend, deform the earlier foliation. These folds have been partly excavated, possibly for research purposes and are exposed in three dimensions.
