Abstract

Name: Carbonate shelf of Northern Caucasus and Precaucasus, Russia

Author: Vitaly G. Kuznetsov

Location: From 41° 30′ to 45° 30′ north latitude and 39° to 48° east longitude, Russia

Geologic time interval: Late Jurassic-Early Cretaceous

Tectonic-sedimentary setting: Epihercynic Scythian platform and Caucacus geosyncline, Tethyan ocean

Basin type: Epeiric shelf

Paleoclimate: Generally arid, semiarid to humid

Platform type: Rimmed carbonate shelf

Platform geometry: Up to 2500–2800 m thick, 100–150 km wide, and up to 750 km long

Facies and fossils: Mixed carbonates and clastics: massive biogenic limestone; interbedded limestone, marl, and sandstone; dolomite; sandstone, siltstone, shale, and anhydrite; corals, bryozoans, stromatolites, brachiopods, bivalves, ammonites, and foraminifera

Systems tracts: Lowstand redbeds and sandstones; trangressive clastics and carbonates; and highstand reefal, lagoonal, and intrashelf basin limestones and fine-grained clastics

Stacking patterns: Shoaling upward cycles of peloidal-bioclastic packstone-grain-stone grading upward to micrite and above to stromatolitic boundstone, grape-stone, and oncoid grainstone
