Chemical analyses of chlorite flakes, as a product of alteration of biotite in the Eocene granitoid rocks of Naghade and Pasveh intrusions have been accomplished by electron microprobe for major elements. Based on 53 point analyses of chlorites from 13 rock samples, their mean structural formula recalculations display that Si cation numbers are less than 5.97 atoms per formula unit (apfu), and ...
This study contributes to our understanding of the evolution Hal?lar Cu-Pb (±Zn) mineralization (NW Turkey) based on mineralogical and geochemical results sulfur isotope data. The area represents local with some Zn brecciated-stockwork vein type along NE–SW fault gouge zone at lower boundary Sakarkaya Düztarla granitoid rocks. Two main zones, consisting sericite–quartz–chlorite ± kaolinite pyri...
CO 2 geological storage will be needed as part of the transition to lower greenhouse gas emissions. During storage, mobilization metals from minerals formation water via rock reactions may a concern for quality. The sources, behavior, and fate metals, however, are not well understood. Metals in calcite cemented sandstone, feldspar-rich ironstone seal drill cores target site were characterized. ...
Sediment gravity flows transport large volumes of sand and clay minerals into submarine systems, which store some the world's major reserves oil gas. However, knowledge about grain-coating mineral formation its role in preserving reservoir quality deep marine settings is poorly documented. Here we present a case study on Agat Formation, deposit interpreted as series turbidites, using multimetho...
