Type material of Paliurus colombii Heer, Populus arctica Hakea and Hedera macclurii Heer from the Atanikerdluk locality (Paleocene, Greenland) was restudied based on original collection, stored in National Museum Ireland, Dublin. All these species were joined under name Zizyphoides (Heer) Seward et Conway, type genus Conway. A lectotype is designated diagnosis this emended. An emended also pres...

During the early Paleogene (59–50 Ma), several short-term global warming events, known as hyperthermal occurred. Negative carbon isotope (δ13C) excursions are a typical proxy for detecting events. recovery from δ13C values returned toward pre-event levels via scavenging lighter C isotopes ocean and sequestrating them within sediments. The biological pump plays key role in this process. Barium (...

Abstract The Zagros orogen, formed by the collision of Arabian and Eurasian continental margins, represents one largest richest oil gas provinces in world. fold-thrust belt records convergence along Neotethys suture zone. By coupling field observations, sandstone modal analysis, U-Pb zircon dating, Hf isotopic data from Upper Cretaceous to Pliocene sedimentary succession Neyriz region, this pap...

sakhtehesar mountain is located in urumieh-dokhtar magmatic belt and is composed of volcanic and subvolcanic rocks (pliocene andesite to dacite) which intruded the volcanics and pyroclastics of paleocene age. three alteration zones including potassic, phyllic and propylitic are recognized in the area. in this paper, the mineral chemistry of magmatic and primary biotite and the mineral chemistry...

The Persian Gulf is part of an asymmetric foreland basin related to the Zagros Orogen. It has been episodically flooded for much of its history which are reflected in sedimentary successions. The evaluation of this succession from depositional trend view, in central Persian Gulf during Paleocene-Eocene, is the aim of this article. The sedimentary rocks physical characteristics effects on seismi...
