Emendation of the Grivska Formation in its type area (Dinaridic Ophiolite Belt, SW Serbia)

Item

Sudar, Milan

Age, microfacies and depositional realm of the Grivska Formation is controversially discussed due to the fact of missing detailed investigations. Based on reinvestigations of the type locality of the Grivska Formation and in adjacent areas following results can be drawn: 1) the Grivska Formation is Late Triassic (Early Carnian to Rhaetian) in age according to conodont dating. 2) Sedimentological and microfacies studies evidenced that the Grivska Formation was deposited on the continental slope and transitional to the Neo-Tethys Ocean. Based on the results of these investigations of the type area and several reference sections in the Dinaridic Ophiolite Belt the Grivska Formation is emended and clearly defined. In the Dinaridic Ophiolite Belt the Grivska Formation occur only as carbonate components and blocks in the ophiolitic mélange. In other tectonic units to the east it can be expected that the continental slope is incorporated in the Middle-Late Jurassic accretionary wedge and therefore only metamorphosed sedimentary rocks may be preserved.

Abstract

sr Age, microfacies and depositional realm of the Grivska Formation is controversially discussed due to the fact of missing detailed investigations. Based on reinvestigations of the type locality of the Grivska Formation and in adjacent areas following results can be drawn: 1) the Grivska Formation is Late Triassic (Early Carnian to Rhaetian) in age according to conodont dating. 2) Sedimentological and microfacies studies evidenced that the Grivska Formation was deposited on the continental slope and transitional to the Neo-Tethys Ocean. Based on the results of these investigations of the type area and several reference sections in the Dinaridic Ophiolite Belt the Grivska Formation is emended and clearly defined. In the Dinaridic Ophiolite Belt the Grivska Formation occur only as carbonate components and blocks in the ophiolitic mélange. In other tectonic units to the east it can be expected that the continental slope is incorporated in the Middle-Late Jurassic accretionary wedge and therefore only metamorphosed sedimentary rocks may be preserved.
