To reveal the genesis of Makeng-style iron polymetallic deposits from SE China in paleo-Pacific tectonic domain, a new analytical method LA-ICPMS garnet U-Pb dating and rare Earth element analysis was conducted for Makeng, Luoyang, Dapai Pantian deposits. The results nine skarn samples these suggested that mainly formed during 137–130 Ma, which is consistent with zircon molybdenite Re-Os ages. ...

The Askartor Be-Mo deposit is located in the southeastern area of Chinese Altay orogenic belt Xinjiang, NW China. Zircon U-Pb data show that there are two periods magmatic activities ore district, namely, Devonian granodiorite (386.8 ± 2.6 Ma) and biotite granite (385.4 4.4 Ma), Triassic two-mica (247.5 2.2 muscovite (231.4 2.0 Ma). zircon age pegmatoid orebody 220.6 1.6 Ma which coincides with...

At El Chucho creek, located to the west of Valle del Cauca department in Colombia, some hydrothermal alterations affecting Buga Batholith rocks and dykes porphyritic quartz-dioritic tonalitic composition were identified. These lithological units host mineral occurrences pyrite, chalcopyrite, molybdenite that occur disseminated or associated with quartz veinlets. The identified phyllic, propylit...

An occurrence of vein U-Mo mineralization is located in the Majerská valley near Čučma, about 7 km to NNE district town Rožňava (Eastern Slovakia). Mineralization hosted acidic metapyroclastics Silurian Bystrý Potok Fm. (Gemeric Unit), and originated following stages: (I.) quartz I, fluorapatite I; (II.) II, zircon, rutile chlorite, tourmaline; (III.) uraninite, molybdenite, U-Ti oxides; (IV.) ...
