Characterization of Lower Permian Carbonate Subaqueous Gravity Flows in Crockett County, Texas
… slopes act as a link to relatively well-studied platform and basin depositional environments. In the southern Midland Basin, the key to understanding the relationship between these environments lies in the allochthonous gravity flow sediments found on the slope. Here, a succession of various …

Outcrop-derived facies model and cycle architecture of the Tansill G27-G28 high-frequency sequences, Rattlesnake Canyon, New Mexico
High-relief, steep-rimmed carbonate margins are significant geologic features documented in a variety of locations throughout the geologic record. The Tansill Formation, the shallow-water platform equivalent of the steep-rimmed Capitan Reef, is the end member of a depositional system that …

Stratigraphy and sedimentology, Cambrian Shady Dolomite, Virginia
… southwestern Virginia, apparently formed in a platform-to-basin setting. Northwest of Austinville, the Shady Dolomite (600 m thick) overlies the Lower Cambrian Erwin Formation and is overlain by the Middle Cambrian Rome Formation. Here the unit consists of ribbon-laminated carbonates (Patterson …

Chemostratigraphy of Carbonate Gravity Flows of the Wolfcamp Formation in Crockett County, Midland Basin, Texas
… Studying these gravity flows along a carbonate platform’s slope can further expand an understanding of the stratigraphy that is filling adjacent basins. The application of elemental analyses can support in identifying mineralogy that impact reservoir quality, especially when conventional testing …

Integrated High-resolution Stratigraphy of the Doushantuo Formation, South China
… of thick carbonate accumulations at the platform margin. Geochemical analysis shows extreme isotopic variability in the Doushantuo Formation that may be the result of pulsed oxidation of a deep oceanic organic carbon reservoir. Oxidation events may have had further implications on the …

Petrography and Diagenesis of Cambrian Dolomite in Tabei Uplift, Northern Tarim Basin, China
… Tabei Uplift present a succession of restricted platform and platform margin carbonates, which are mostly dolomitized. Based on an integrated multidisciplinary approach which incorporated one hundred and fourteen meters of core descriptions from seven wells, one hundred and fifty-two thin-section …

Milankovitch-driven cyclicity and climate controlled dolomitization of a Late Triassic carbonate platform, Hungary
The Late Triassic platform carbonates of the Transdanubian Range, Hungary were part of a passive margin platform at the southwestern end of the Triassic Tethys now occurs in a single fault-bounded terrain. The Hungarian platform is made up of meter-scale, precessional (~20 k.y.) carbonate cycles. …

Biostratigraphy, lithostratigraphy, ammonite taxonomy and microfacies analysis of the Middle and Upper Jurassic of northeastern Iran
… are part of a carbonate system consisting of a platform and adjacent slope to basin. Five major environments are represented: Tidal flat, shelf lagoon, and platform margin barrier as parts of the carbonate platform, and slope to basin representing open marine conditions. The sediments of the …

Micropalaeontology, Palaeoenvironments and Sequence Stratigraphy of the Sulaiy Formation of Eastern Saudi Arabia
… model namely the Arabian Rimmed Carbonate Platform. This palaeoenvironmental depositional model is characterised by two different platform regimes. They are the Platform Interior and the Platform Exterior each of which have unique sedimentary lithofacies zones that produce different types …
