Dulai, A.: Early Jurassic brachiopods from the basal layers of the Pisznice Limestone of Lábatlan (Gerecse Mts, Hungary)

The sparite-micrite ratio is 50.3% in layer I of Póckő, similarly high as in the lower layer of the Tölgyhát quarry. The matrix is entirely micritic in layer 2 of Póckő, although only three specimens were found from here. The percentage of sparitic infilling is decreased in layers 3 and 4 of Póckő (37.5% and 35% respectively), but not as significantly as at the other locality. 5 m 12 Dachstein Limestone 13 p, w cd Ü R M >15 c S3 bû tu h ou Xt on •*-» o o KJ oo CL) bű JD 0) Cd «1 •g cd S :s S eu N Q .2 g o I -c ?
