The well-known fossiliferous and lithologically variable Middle Devonian Shaly-Calcareous Skały Formation in the Łysogóry Region (northern part of Holy Cross Mountains, central Poland) was studied for first time terms elemental geochemistry, carbon isotope stratigraphy limestone microfacies. Three Lower to Givetian marly-limestone successions, exposed at Miłoszów, represent middle outer facies ...

Purpose. The work studies Sinjar formation (upper Paleocene lower Eocene) within the Bazyan anticline in Sulaimaniyah region (northeastern Iraq). facies analysis is based on petrographic study of limestone deposits and essential to identify their nature. sediments that formed have a high content skeletal granules which include small amount red algae residues unicellular organisms-foraminifera. ...

In order to decipher the paleo-depositional environments, during Late Jurassic Early Eocene syn-rift stage, at margins of Ionian basin, two different areas with exposed long sequences have been selected, Kastos Island (external margin) and Araxos peninsula (internal margin), were examined by means microfacies analysis biostratigraphy. On Island, based on lithological sedimentological features, ...

An integrated study based on field observation, petrography, and scanning electron microscopy (SEM) the Early–Middle Eocene carbonate rocks has been carried out, which were deposited in Ceno-Tethys Ocean. The area of Yadgaar Section lies eastern margin Upper Indus Basin, Pakistan. Margalla Hill Limestone Chorgali Formation act as reservoir other parts basin are also present Section. lack compre...

The Yamama Formation represents a part of the Late Berriasian-Aptian sequence, deposited during Early Cretaceous period within main shallow marine depositional environment. studied area covers three oil fields; Sindbad field, Halfaya and Ad'daimah located in southeastern Iraq. Six major microfacies were recognized succession represented by to determine recognize paleoenvironments. These are; Pe...

Abstract Sections at Baghuk Mountain, 45 km NNW of Abadeh (Central Iran), have excellent exposures fossiliferous marine Late Permian to Early Triassic sedimentary successions. Detailed bed-by-bed sampling enables the analysis microfacies changes three successive rock units across Permian–Triassic boundary. The Hambast Formation is mainly result biogenic carbonate production. Its dominated by bi...
