Field investigation, Microfacies analysis, and biostratigraphy have been carried out in the central parts of Ionian Basin (Aetoloakarnania area, Western Greece) order to decipher depositional environments that developed during accumulation Upper Cretaceous Eocene carbonate succession. Three different Standard types (SMF) observed, corresponding two (Facies Zones or FZ) a platform progradation. ...

The early Devonian Greywacke Conglomerate Formation of the Lanark Basin, southwestern Midland Valley Scotland, has been exposed by a new road cut in Glenbuck area, East Ayrshire, enabling high-resolution sedimentological analysis this unusually high-quality section. This study provides facies sedimentary rocks and comparison with contemporaneous bedrock sections from across Basin adjacent South...

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...

Copper-bearing skarn zone in east of Sungun-Chay river is located about 100 km NE of Tabriz, and was developed along the contact of the mineralized porphyry granitoid stock (Oligo-Miocene) with impure carbonate rocks (Upper Cretaceous). Both endoskarn and exoskarn occurred in this zone. Endoskarn is narrow (~0.5-2m) whereas exoskarn is relatively broad (25-55m) and contains minerals such a...

This study investigates the interplay of evolving tectonic and submarine sedimentation processes in northwest Aegean Sea using marine multichannel seismic profiles. We identify an extensive basin developing Thermaikos Gulf inner shelf, outer slope leading to 1500 m deep West North Trough (NAT). establish unconformable extent Eocene Oligocene sequences on upper shelf trace their continuation dee...

Abstract The Miocene Zhujiang Formation is the key horizon for oil and gas exploration in Pearl River Mouth basin of northern South China Sea. With help core observation, seismic attributes various analytical data, sedimentary facies marks, distribution depositional model forced regression basin, Sea, have been studied. Forced regressive deposits were formed during period when relative sea leve...
