From nappe stacking to exhumation: Cretaceous tectonics in the Apuseni Mountains (Romania)
New Ar-Ar muscovite and Rb-Sr biotite age data in combination with structural analyses from the Apuseni Mountains provide new constraints on the timing and kinematics of deformation during the Cretaceous. Time-temperature paths from the structurally highest basement nappe of the Apuseni Mountains in combination with sedimentary data indicate exhumation and a position close to the surface after ...
متن کاملFacies, 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 کاملbiostratigraphy of upper cretaceous deposits based on calcareous nannofossils in south-east of lar
in this research, calcareous nannofossils of the upper cretaceous deposits of the souteast lar have been investigated. the upper cretaceous deposits have a thickness of 173 meters and consist of thick layers of marl and marly limestone. for introducing calcareous nannofossil assemblages and biozones, 141 slides of the gurpi formation in southeast of lar area have been studies which led to ident...
متن کاملCalcareous nannofossils biostratigraphy of the Campanian-Danian interval, Gurpi Formation in the Zagros Basin, SouthWest Iran
This study presents calcareous nannofossils biostratigraphy of the Campanian‒Danian interval at the Gurpi Formation in the southwest of Ilam Province, in the Zagros Basin. The studied sequence of the Gurpi Formation mainly consists of marly shale and limestones. The thickness of Gurpi Formation was measured as approximately 230 m. Forty-five species belonging to twenty-eight genera were recorde...
متن کاملRecord bio-events and study the distribution of calcareous nannofossils in Cretaceous-Paleogene sediments, Neo-Tethys Ocean realm
In the present study, the sediments of the Gurpi Formation in the Jafarabad section located in the southeast of Ilam were examined from the point of view of calcareous calcareous nannofossils. The sediments of the upper part of Gurpi Formation with a thickness of about 42 m are composed of limy marl sediments. In this study, 34 species belonging to 22 genera from the group of calcareous nannopl...
