Abstract The Plio-Quaternary tectonic evolution of the central sector Sicilian Channel and resulting morphostructural setting have been analyzed using a large geophysical dataset consisting multichannel seismic profiles, which some them never published, available bathymetric data. This area hosts two regional-scale domains that registered complex pattern deformation occurred since Early Pliocen...
Geochemical analysis of sediments recovered from NS-1 well and NS-2 well, Leuma Field, Coastal Swamp Depobelt, Niger Delta Basin was done to establish tectonic setting provenance. Data for ten major elements forty-three trace were obtained two boreholes. The geochemical signals display systematic stratigraphic trends in the wells that depict one source terrain. To determine provenance sediments...
Gabbroic pluton of Bagham is located in southeastern Ardestan and has intruded into Eocene volacanic rocks. The study area is a part of Central Iranian zone and Urumieh-Dokhtar magmatic belt. Clinopyroxene, plagioclase and amphibole are main minerals in the pluton. Mineral chemistry studies show that clinopyroxenes are augite and are plotted in almost medium pressure field. The clinopyroxene co...
The study area is located at 130 km northwest of Nehbandan in South of Khorasan and is a part of the rectangular Chahvak (Dehsalm). Dacite, rhiodacite, andesite, rhyolite, tuff and lithic tuff with Eocene age are recognized in the study area. According to mineralogy, mentioned rocks include plagioclase, quartz, pyroxene, amphibole, biotite and alkaline feldspar. Plagioclase consists of zonal st...
