Facies, sedimentary environments and sequence stratigraphy of Cretaceous deposits in the northwest of Azerbaijan, Iran
The Cretaceous deposits in Morakan, located in the northeast of Khoy, a town in western Azerbaijan province, Iran, are primarily made up of carbonate rocks. These deposits, which are of 717 meters thick, lie on the clastic facies of Jurassic and are covered with beneath the pelagic beds of the Upper Cretaceous. To investigate the facies, sedimentary environment and sequential stratigraphy of th...
متن کاملDepositional environment, diagenesis, sequence stratigraphy and geochemistry of Lower Cretaceous carbonate unit (K1) of Kuh-khangormas, Tuyserkan (Sanandaj-Sirjan Zone)
Abstract Lower Cretaceous carbonate units of the Kuhzation, karstification and dolomitization, studies of 40 samples of these carbonate units indicated aragonite as original mineralogy in closed to semi-closed diagenetic system.
متن کاملPalynofacies-based sequence stratigraphy of the Upper Cretaceous strata (Abderaz Formation) in east of Koppeh-Dagh Basin, Northeast of Iran
The Upper Cretaceous strata were studied in a composite stratigraphic section named here Padeha-Baghak section in east of Koppeh-Dagh basin, north east of Iran. In this study, palynostratigraphy, palynofacies and depositional environment history of Abderaz Formation were integrated with sequence stratigraphy. Determination of sea level history and sequence units of the Abderaz Formation using s...
متن کاملThe Lower Cretaceous Figuera Lava and Fajardo Formation in the Stratigraphy of Northeastern Puerto Rico
The Figuera Lava, the oldest stratigraphic unit now recognized in northeastern Puerto Rico, and the overlying Fajardo Formation are redescribed and the name Figuera redefined and reinstated for formal use. Previously, lower Tertiary strata some distance from the type areas of the Figuera and Fajardo were correlated with the units by reconnaissance. Recent detailed mapping and paleontology now p...
متن کاملdepositional environments and sequence stratigraphy of the sorkh shale formation (lower triassic) in the tabas block
the sorkh shale formation (lower triassic) crops out in parts of tabas block. this formation is composed of limestone, dolomite, sandstone, shale and gypsum. its lower contact with the permian rocks and its upper contact with the shotori formation is marked by distinct erosional unconformity. to determine the depositional environments of the sorkh shale formation, stratigraphic sections of goda...
