Late Paleocene to early Oligocene dinoflagellate cysts of the Zagros basin, west Iran (palaeopalynology and palynostratography)

Depositional Environment and Sequence Stratigraphy of the Oligocene-Miocene Deposits North and East of Dehdasht, Izeh Zone, Zagros Basin, Iran

In this study, four well-exposed outcrops of the Asmari Fm in the southeastern part of the Izeh Zone of the Zagros Mountains were measured and sampled. In this region, the Asmari Fm is Oligocene to Early Miocene in age as determined by large benthic foraminifera. Based on depositional geometries, biogenic contents and lateral and vertical variations of facies, three depositional models are prop...

PALYNOSTRATIGRAPHY AND PACAIEOGEOGRAPHY OF EARLY PEFIMM STRATA IN THE ZAGROS BASIN, SOUTHEAST SOUTHWEST IRAN

A totall of 500 Early Permian samples from the Chal-i-Sheh Formation in the Zagros Basin were examined palynollogically in order to determine the stratigraphical age of the formation and to assess the palaeogeopaphicd relatianships of this basin to the Southern and Northern Hemispheres during the Early Permian. Fifty-eight taxa were recorded including 46 pollen, 10 spore and 2 acritarch spe...

The West Philippine Basin: An Eocene to early Oligocene back arc basin opened between two opposed subduction zones

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

Magnetostratigraphy of Late Eocene - Early Oligocene Strata from the CRP-3 Core, Victoria Land Basin, Antarctica

The Cape Roberts Project was successfully completed in the austral spring of 1999 with drilling of the 939.42-m CRP-3 drillhole, located 2-km west of the CRP-2/2A drillhole. The CRP-3 core comprises a 790-m Cenozoic (glacio-) marine sequence separated from underlying Devonian basement rocks by a c. 30-mthick dolerite conglomerate of undetermined age. Here, we present the results of a palaeomagn...
