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...
متن کاملFacies and Depositional Environments of Cretaceous Siliciclastic Sediments in Al Bauga Area , Northern Sudan
The outcropping Cretaceous siliciclastic sediments in the Al Bauga area in Northern Sudan reach a maximum thickness of about 30 meter. They rest with angular unconformity on tilted Precambrian basement rocks and are capped by Tertiary-Quaternary basalts forming a type of nonconformity. The sedimentary sequence was subdivided into three major units separated by two disconformities. The lower uni...
متن کاملAngiosperm-like pollen and Afropollis from the Middle Triassic (Anisian) of the Germanic Basin (Northern Switzerland)
Here we report on angiosperm-like pollen and Afropollis from the Anisian (Middle Triassic, 247.2-242.0 Ma) of a mid-latitudinal site in Northern Switzerland. Small monosulcate pollen grains with typical reticulate (semitectate) sculpture, columellate structure of the sexine and thin nexine show close similarities to early angiosperm pollen known from the Early Cretaceous. However, they differ i...
متن کاملAlgae (Dasycladales) from the Upper Triassic Nayband Formation (northeast Iran)
Dasycladales are relatively abundant in the bedded limestones of the Bidestan and Howz-e Khan members of the Late Triassic Nayband Formation in central Iran. In a locality south of the town of Naybandan (northwest of Dig-e Rostam), several Rhaetian dasycladacean algae were found in thin sections. The following taxa are described: Diplopora phanerospora Pia, Naybandoporella rhaetica nov. gen. no...
