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...

the aitamir formation (albian- cenomanian) in the kopet- dagh basin consists of fine to medium grained sandstone, siltstone, shale and limestone. its lower contact with the sanganeh formation is gradual and its upper contact with the abderaz formation is unconformable. field and petrographic studies of the aitamir formation in artenj and ghorghoreh sections, located in bazangan area- east of ko...

Sequence stratigraphy is the study of genetically related facies within a framework of chronostratigraphically significant surfaces, where the depositional sequence is considered to be the fundamental unit for sequence-stratigraphic analysis (Van Wagoner et al., 1990). The depositional sequence is defined as a genetically related succession of strata bounded by unconformable surfaces and their ...

the asmari formation is a thick carbonate sequence in zagros foreland basin. it was deposited during oligocene – early miocene ages. in order to interpret the depositional environment and sequence stratigraphy, firuzabad section were compared with 4 sections of asmari formation in the zagros basin. four different sub environments were identified in the asmari formation based on microfacies anal...

The Upper Bajocian- Lower Bathonian succession in the Kopet-Dagh Basin of NE Iran represents fluvio-deltaic to turbidite deposits. The Kashafrud Formation provides an excellent opportunity to study the interplay between deep-water sedimentation and syndepositional tectonic subsidence (or uplift) in the region. The effects of these processes caused sea-level changes, variation in depositional se...

The incipient island-arc system of southern Central America (Cretaceous early Oligoccne) is characterized by thick turbidite systems. which mainly filled inner fore-arc troughs. Outcrop data show four. second-order depositional sequences in the deep-water sedlments. The formation of these depositional sequences is strongly related to the morphotectonic evolution of the island-arc system. Each d...

This study shows that ichonology can be used to refine sequence stratigraphy as well as to interpret the depositional environment of the Kalat Formation (Upper Maastrichtian) in the Central Kopeh- Dagh Basin (NE Iran), Dareh-Gaz section. Field studies and petrography of these deposits led to recognize four lithofacies and nine subfacies that formed in the tidal flat (lithofacies A), lagoon (lit...

The Ordovician System, cropping out in southern and west-central Jordan, consists entirely of a 750 m thick clastic sequence that can be subdivided into six formations. The lower Disi Formation starts conformably above the Late Cambrian Umm Ishrin Formation. According to Cruziana furcifera occurring in the upper third of the Disi Formation, an Early Ordovician age is con®rmed. The Disi Formatio...
