the study area is located in the central iranian tectono-magmatic zone, which is known for its world-class ioa-type iron ore deposits. the advanced space borne thermal emission and reflection radiometer (aster) and landsat enhanced thematic mapper plus (etm+) image-processing techniques, were used in satellite imagery through conventional and also modern processing methods including band ratios...

Key constraints related to the nature of alteration and mineralization in geologically complex economically important iron oxide copper–gold (IOCG) systems remain highly speculative, especially, physicochemical characteristics hydrothermal fluids. This study was conducted on samples from Khetri Copper Belt (KCB) western India that hosts several IOCG-type deposits. The aims constrain qualitative...

Abstract The Huayangchuan ore belt is located in the western segment of Xiaoqinling Orogen southern margin North China Craton (NCC), and hosts voluminous magmatism significant U?REE?Mo?Cu?Fe polymetallic mineralization. However, geochronological framework various mineralization phases this region poorly understood. Here, we present new Re?Os isochron ages on magnetite from Caotan Fe deposit (2 ...

The principal objective of the current study was to elucidate the potential influence of acid mine drainage (AMD) pond on neighboring farmer's wells in the Podwiśniówka area (south-central Poland), using North American Shale Composite (NASC)-normalized rare earth element (REE) concentration profiles. The well waters generally displayed a distinctly positive Eu anomaly similar to that of parent ...

sorkheh-dizaj apatite-iron oxide deposit is located 32 km southeast of zanjan. the area is situated within the tarom subzone of western alborz-azarbaijan structural zone. the oldest units at the sorkheh-dizaj area are eocene trachyte, trachyandesite, olivine basalt and volcanoclastic brecciate tuff and lapilli tuff which intruded by a quartz-monzonite, monzonite and granite subvolcanic pluton o...

This study reports major, minor, and trace element data and Sr isotope ratios for 11 uranium ore (uraninite, UO2þx) samples and one processed uranium ore concentrate (UOC) from various U.S. deposits. The uraninite investigated represent ores formed via different modes of mineralization (e.g., highand lowtemperature) and within various geological contexts, which include magmatic pegmatites, meta...

In this study two small, but genetically related iron carbonate deposits Mačje Jame and Vranjski Potok, south west of Busovača (MBSM), located in the pre-Devonian metamorphic complex were investigated in detail. Analyses of the main chemical components, trace elements, REE, isotope composition of C, O, S, 87Sr/86Sr ratio of rhyolite, plot of REE normalized to CI chondrites and a microscopic stu...
