Distribution and type of organic matter in Cretaceous to Tertiary source rocks in Soroosh and Nowrooz fields, Persian Gulf
Detailed organic petrography analysis were conducted on drill core and cutting samples from the Nahr Umr (Middle Albian), Burgan (Lower Albian) and Ratawi (Hauterivian) formations on the Soroosh and Nowrooz fields, NW part of the Iranian sector of the Persian Gulf. The thermal maturity of the Middle Albian Nahr Umr Formation appears to have reached the top of the oil window. The underlying Burg...
متن کاملBiostratigraphy and paleoecology of Cretaceous rocks based on calcareous nannofossil in Sarayan section, East Iran
Calcareous nannofossil assemblages recovered from a long, continuous section have been described from the Sarayan region in Lut Block in east Iran. The marine Upper Cretaceous sediments of this section yield medium diverse and well-preserved calcareous nannofossil assemblages. A structural analysis of Upper Cretaceous calcareous nannofloras has revealed 30 nannofossil species. A revised zonatio...

متن کاملStratigraphy and remanence acquisition of a palaeomagnetic reversal in alluvial Siwalik rocks of Pakistan
A high-resolution record of a palaeomagnetic reversal is documented in Miocene alluvial rocks of Pakistan. We examined lateral variability of lithostratigraphy and palaeomagnetic stratigraphy through the same palaeomagnetic reversal in six correlated sections. Each section contains one or more palaeomagnetic sites with directions between fully reversed and fully normal. The position of the reve...
متن کاملUpper Cretaceous Foraminifera from Japan
IN THIS PAPER the discovery in Japan of smaller Foraminifera from the Upper Cretaceous strata is recorded for the firsi: time. This contribution, in addition to its specific biostratigraphic application in Japan, has further interest by reason of its extension of the geo. graphic range ,of the widely distributed Cretaceous pelagic foraminiferan, Globotruncana. In the north Pacific region, Globo...
