Abstract

Sequence stratigraphic analysis of Triassic formations in the Balaton Highland region revealed that in addition to sea-level-changes, climatic changes and tectonic effects also played an important role in the determination of the fades characteristics as well as the setting and features of the depositional sequences. However, the relative importance of these factors differed in the successive evolutionary stages. In the Early Triassic the moderately and uniformly subsiding shelf was very sensitive to sea-level changes. During the Early to Middle Anisian, mainly the effects of climatic changes are detectable. A drastic reduction of terrigenous input at the beginning of this stage can be attributed to a climatic change and it is primarily climatic conditions which may have determined whether syndiagenetic dolomite formation or organic rich lime mud deposition prevailed on the restricted inner ramp. From the Middle Anisian to the Late Carnian tectonic movements played the most decisive role. At the beginning of this stage segmentation of the shelf began, resulting in the differentiation of platforms and basins. Sea level changes manifested themselves in subaerial exposure and inundation of the platforms. Filling up of the basins began in the Carnian, when most probably due to a remarkable climatic change terrigenous influx increased significantly. During this period eustatic sea level changes may have played an important role in the determination of the sedimentation pattern.
