REMARKS ON THE STRATIGRAPHY AND BRACHIOPOD PALAEOBIOGEOGRAPHY IN THE LOWER JURASSIC HIERLATZ TYPE LIMESTONE FACIES; THE CHOC UNIT, CENTRAL WESTERN CARPATHIANS

Rok, strany: 1994, 195 - 202

Bioclastic grainstones and packstones occur in three small thrust sheets of the Choc Unit in the Tatra Mts., called the Konczysta, Uplaz and Brama Kantaka scales. They are similar to the Alpine Hierlatz facies. The bioclast faunas are dominated by crinoid ossicles and brachiopods and pelecypod shells. Their sedimentation is related to tilting blocks originated during the opening of the Western Tethys. Numerous brachiopods enable the age of the limestones to be determined. The limestones from the Brama Kantaka scale may be assigned to the Domerian, while the limestones of the Konczysta scale may be ascribed to the Upper Sinemurian-Domerian. The limestones of the Uplaz scale contain Hettangian-Sinemurian brachiopods which are mixed together with Domerian brachiopods. The Domerian brachiopods belong to the NW European biogeographical province. The Hettangian-Sinemurian brachiopods are probably allochthonous and belong to the Alpine biogeographical province. Thus, the age of the Hierlatz type limestones of the Uplaz scale is Domerian.
