The East Kunlun Orogenic Belt is considered as one of the important gold mineralization regions in Tethys tectonic domain. These orogenic deposits are related to intermediate-acid intrusions formed at end Paleo-Tethys evolution, but petrogenesis controversial. This paper presents a new study on geochemistry zircon U-Pb, O, S, and Pb isotopic compositions Asiha quartz diorite, granite porphyry, ...

Coal-fired thermal power stations presently account for nearly 52 % of the total generation in India’s sector. There is a constant need to monitor performance coal-fired plant auxiliaries/ components and ensure maintenance these optimum levels operating parameters achieve trouble-free quality consistent electric output. Coal’s mineralogical content its physical decide coal pulverizer terms grou...

Thermochemical sulfate reduction (TSR) commonly occurred in the dolostone reservoirs of Upper Permian Changxing Formation (P3c) Yuanba (YB) gas field, Sichuan Basin, yet controversy remains regarding source required for TSR. To trace sulfate, sulfur and strontium isotopic compositions were measured three diagenetic celestite (SrSO4) samples found P3c YB field. In addition, Carbonate-associated ...

H-pit is one of the significant ore lenses Chatree mine in Thailand. Au-Ag mineralization mainly occurs as veins, stockworks, and minor breccias hosted by volcanic volcaniclastic rocks. Disseminated pyrites are commonly present near mineralized veins hanging wall zone. This study aims to assess acid rock drainage (ARD) potential heavy metal content from area. The results indicate that a acid-fo...

This paper describes a newly discovered Bi-Cu±Au mineralization co-occurring with Pb-Zn-Ag hydrothermal within the Kizhnica-Hajvalia-Badovc ore field, central Kosovo, Vardar Zone. The mineralogy of two styles was described using EPMA in combination reflected and transmitted light microscopy. Hydrothermal Cu-Bi veinlets Kizhnica andesite quarry consist Bi sulfosalts (bismuthinite, cosalite, aiki...

Coastal hypoxia is a worldwide concern. Even though seasonal has been reported on the northwestern Black Sea shelf since 1970s, little known about oxygenation in this area over Holocene. With multiproxy approach, work aimed to detect potential hypoxic events two gravity cores. Our results demonstrate that most common proxies of are irrelevant for coastal environment. For instance, Ammonia-Elphi...

Lower Permian Fengcheng Formation is considered to be a high-quality alkaline lacustrine shale oil resource in the Junggar Basin, NW China. Based on core and thin section observation, X-ray diffraction, scanning electron microscope, low-pressure N 2 adsorption, high-pressure mercury intrusion porosimetry, different lithofacies, pore structures were examined. According mineral composition, shale...

The Alta Floresta Gold Province (PAAF) is abundant in gold deposits and, located the state of Mato Grosso, Brazil, an ideal place to study geoelectric signature mineralization. Auriferous mineralization occurs along shear zones quartz veins and disseminated granites this region. Ores are associated with oxides sulfides, mainly pyrites. To identify primary or continuities mineralized zones, data...
