Paleocene and Lower Eocene deposits in SW Iran are known as Pabdeh formation.Pabdeh formation is one of the most important lithostratigraphy unit as source rock has been deposited in Zagros basin over an extremely long period in time. The area under research is the Ghachsaran 55 subsurface Section located from the Ghachsaran oil field in Dezful embeyment in zagros fold zone. The Lower boundry...
Results of this study have included five fieldwork papers (Bickford and Kenyon, 1988; Kenyon and Bickford, 1989, Bickford, et al., 1989 and 1990; Cathyl-Bickford, 1992), one stand-alone paper (Kenyon, Bickford and Hoffman, 1991) and a set of fourteen maps (CathylBickford and Hoffman, 1998). In the course of this work, 21 stratigraphic sections were measured, and four of the sections were publis...
The Triassic section north of Currie in southern Elko County, Nevada, is almost 500 m thick and is assigned to the Thaynes Group and overlying Shinarump Formation of the Chinle Group. The Thaynes Group disconformably overlies the Permian Gerster Formation and is mostly calcareous shale with interbedded wackestones that yield marine invertebrate fossils, especially ammonoids. The Shinarump Forma...
In New Mexico (NM), Upper Triassic strata of the Chinle Group are nonmarine siliciclastic red beds containing an an extensive fossil record that demonstrates a late Carnian to early Rhaetian age, about 230-203 Ma. Magnetostratigraphic studies of the Chinle Group in NM began in the 1970s and have produced complete Chinle magnetostratigraphies in east-central NM (Tucumcari basin) and north-centra...
Over the last few decades, numerous geological studies have been carried out in South Shetland Islands, which greatly contributed to a better understanding of its evolution. However, attempts conducted correlate units throughout this archipelago. We present herein review literature available we use propose lithostratigraphical correlation that constitutes coherent stratigraphy for main Mesozoic...
