the berriasian-valanginian fahliyan formation forms one of the giant reservoirs in the subsurface of the abadan plain, onshore iran. a detailed petrographical analysis of the available cores and thin sections revealed that the different diagenetic parameters influenced the reservoir quality of the fahliyan formation in this field. the fahliyan formation has been influenced by three diagenetic e...

Purpose. The work studies Sinjar formation (upper Paleocene lower Eocene) within the Bazyan anticline in Sulaimaniyah region (northeastern Iraq). facies analysis is based on petrographic study of limestone deposits and essential to identify their nature. sediments that formed have a high content skeletal granules which include small amount red algae residues unicellular organisms-foraminifera. ...

Absbvct New petrographic and chemical data of volcanic rocks from the Metales Belt, Rio de las Tunas area, in the Frontal Cordillera of Argentina are presented. The rocks display a broadly basaltic composition. ‘PNO varieties of basaltic dikes can be differentiated. One group, whose mineralogy comprise essentially tremolite-actinolite, plagioclase, pyroxene and limited amounts of olivine as the...

The present study was carried out on commercial types of Aswan granite used as building and decorative materials. Nearly 29 granitic rocks samples from 11 classes (black Aswan, red dark Rosa, light yellow Verdi, grey Shirka, Gandolla, Forsan, Nefertiti, Royal, white Halayeb) were collected three stations near city for petrographical description assessment natural radioactivity. granites conduct...

In this study, Hallaçlar Volcanites located in Bayramiç-Çanakkale region were evaluated terms of strategic element contents. Mineralogical-petrographical and geochemical investigations carried out on the samples which taken from outcrops with intense hydrothermal alteration. The stratigraphy study area consists Sütüven Formation (Kazdağı Metamorfites), Çetmi Ophiolitic Melange, Evciler Pluton V...

Better characterization features borne from long-term crustal modification processes is essential for understanding the dynamics of large basin-forming impact structures on Earth. Within deeply eroded 2.02 Ga Vredefort Impact Structure in South Africa, melt dikes are exposed at surface. In this study, we utilized a combination field, remote sensing, electrical resistivity, magnetic, petrographi...
