the asmari formation in tang-e surkh section is composed of 294 meters of thin to medium bedded and thick to massive bedded limestone associated with marly limestone. the studied section is located in the northwest of interior fars. based on deepening and shallowing patterns of microfacies, one hst and one third-order depositional sequence during rupelian and two third-order depositional sequen...

We explored the influence of a variety geometric and mechanical factors in evolution décollement folds above weak level sedimentary sequence. Under an applied overburden pressure, we construct nine discrete element models (DE-models) to test effects stratigraphy, thickness layer, number strong layers within cover The aforementioned parameters on structural style fold belts that develop during p...

Crowns of four crinoid species, Talarocrinus planus Weller, 1920, Phacelocrinus longidactylus (McChesney, 1860), Ampelocrinus mundus? Kirk, 1942, and Phanocrinus maniformis (Yandell and Shumard, 1847) are reported from the limestones of the Wymps Gap Member of the Greenbrier Formation in northern West Virginia. Collectively these species indicate an early Chesterian age for the Wymps Gap Member...

The pre-Variscan sequence of the Carnic Alps is exposed across state border between north-east Italy and Austria. It includes Middle Ordovician to Lower Pennsylvanian rocks that, although affected by both Variscan Alpine orogeny, preserve continuous non-metamorphosed successions. Depositional settings vary from shallow water open marine environments. Remarkable presence largest Devonian reefs E...
