Organic geochemical characteristics and depositional environment of Late Miocene aged Honaz (Denizli) coal series

Depositional History of Miocene-Age Sediments from the Weddell Sea, Antarctica, Using Sedimentological and Geochemical Proxies

Understanding the stability of Antarctic Ice Sheets is a key to understanding past climates and the response of ice-sheets to warming. In this thesis, I examined the middle through upper Miocene marine sedimentological and geochemical record in the Weddell Sea. Sediments were recovered at Ocean Drilling Program (ODP) Site 694 located in 4653 m of water in the northern Weddell Sea Abyssal Plain,...

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...

Relationship Between Depositional Facies and Reservoir Characteristics of the Oligo-Miocene Asmari Formation, Aghajari Oilfield, SW Iran

The present study focuses on facies analysis and the reservoir characteristics of the Asmari Formation in the Aghajari oilfield (located in the Zagros fold-thrust belt, southwest Iran), and how they are linked to depositional environments and reservoir characteristics. This formation consists of about 380 m carbonates with some siliciclastic intercalations. Based on the integration of 1200 m of...

Late Miocene ostracods from the Solimões Formation (Western Amazonia): geochemical and palaeontological analyses

Geological and Geochemical Features of Alborz Basin Coal Deposits, Iran

The Alborz coal basin is located in northern part of Iran. The coal deposits of Shahrood in eastern Alborz, Zirab in central Alborz and Abyek in western Alborz were studied as typical coalfields of the basin. Shemshak Formation which is the main coal-bearing sequence was formed during the Triassic-Jurassic in the basin. It consists of sandstone, siltstone, shale and claystone, which variedly al...
