introduction the study area is located in central part of the khaf- kashmar-bardeskan belt which is volcano-plutonic belt at the north of the dorouneh fault in the north of lut block. the north of the lut block is affected by tectonic rotation and subduction processes which occur in the east of iran (tirrul et al., 1983). the magmatism of lut block begins in jurassic and continues in tertiary (...

The Tonggou deposit is a porphyry Cu and vein-type Cu-Zn mineralization system located in the Bogda Orogenic Belt, north of Eastern Tianshan. Systematic fluid inclusion analyses were performed on granular quartz from magnetite–quartz stage pyrite–chalcopyrite–quartz mineralization. During early mineralization, ore-forming fluids at high temperatures (450–501 °C) salinity (51.2–55.2 wt.% NaCl eq...

Abstract A current mineral exploration focus is the development of tools to identify magmatic districts predisposed host porphyry copper deposits. In this paper, we train and test four, common, supervised machine learning algorithms: logistic regression, support vector machines, artificial neural networks (ANN) Random Forest classify metallogenic ‘fertility’ in arc magmas based on whole-rock ge...

This study outlines a novel and sustainable electrodeposition–redox replacement (EDRR) method to produce Cu/Zn alloys using simulated hydrometallurgical Zn solution containing 200 ppm Cu, 65 g/L Zn, 10 H2SO4. The results indicate that by tailoring the EDRR parameters, like deposition time, agitation conditions, with controllable properties including chemical composition, microstructures, colora...

This paper presents the results of a comparative assessment effectiveness sorption purification aquatic medium and fertile soils using native forms bentonite clays deposits in Belgorod region (Russia) from heavy metal ions (Cu 2+ , Fe 3+ Cr Pb ) radionuclides ( 137 Cs, 85 Sr, 233 U и 239 Pu). It was revealed that during model water systems, most absorbing activity is shown by natural Polyana Ne...

Palaeoenvironmental research in the Southern Levant presents a series of challenges, partly due to the unequal distribution of palaeoenvironmental records and potential archives throughout the region. Our knowledge of climatic evolution, during the last approximately 25,000 years, is of crucial importance to understand cultural developments. More local, well-dated, multi-proxy studies are much ...
