Abstract

Results of the mapping in a scale of 1:10 000 of an area lying 4km east to Komlo, in Mecsek Mts., Southern Hungary are presented. The following formations are described: Aalenian-Bajocian grey mottled marl (Fleckenmergel), Bathonian red, nodular calcareous marl, Callovian greenish-grey cherty limestone, Oxfordian light grey cherty limestone, Kimmeridgian red, nodular, cherty limestone, Tithonian white, cherty limestone with intraclasts, Lower Cretaceous alkaline basalt and Recent calcareous tufa. Palaeontological, petrographical, microfacies, sedimentological, heavy mineral, X- ray and DTA investigations indicate open marine sedimentation during Middle and Late Jurassic. The sea deepended from the Aalenian-Bajocian onwards, reaching its maximum depth during Callovian-Oxfordian time. Decrease of depth followed later. A Lower-Middle Bathonian profile with an abundant ammonite fauna is described for the first time. - from Authors
