2023年3月1日 · Molybdenite mineralization occurred in two ore blocks, Xiaojiayingzi (0.11 Mt Mo) and Kangzhangzi (0.02 Mt Mo). In the Kangzhangzi ore block, Mo mineralization is concentrated in skarn adjacent to a deep-seated granite porphyry, with minor disseminated and quartz veinlet mineralization within the granite porphyry.

2024年8月1日 · The Brejuí W-Mo skarn deposit is the main scheelite deposit of the Seridó tungsten province (Borborema province, NE Brazil). It constitutes the largest Brazilian W ore reserve. The orebodies are hosted in the metasedimentary Jucurutu Formation of the Seridó Group (650–610 Ma), close to the margin of the Neoproterozoic Acari pluton ...

2024年3月22日 · This study proposes a distal Cu-Mo skarn ore deposit model associated with granitoid dikes and some implications for mineral exploration in the Qinling orogenic belt and elsewhere. Banchang is the largest Cu-Mo deposit (348 Mt @ 0.32% Cu and 428 Mt @ 0.07% Mo) in the Qinling orogenic belt, Central China.

2000年9月1日 · The Hunt Mo skarn deposit is one of the best examples of a late tectonic, granitic pegmatite-related, skarn system in the Grenville province. An Re-Os age of 1069 ± 11 Ma was obtained from a molybdenite crystal (6.4 ppm Re) hosted in proximal skarn (sample 50O) consistent with a contact metasomatic origin related to the granitic body.

2020年9月1日 · The Xingjiashan deposit, hosted by the Paleoproterozoic metamorphic rocks and the Mesozoic granitic stock, is the largest W-Mo skarn deposit in the Jiaodong peninsula. Except for the most economic molybdenite, there is also some hydrothermal scheelite bearing various Mo contents (MoO 3 up to 30.9 wt%) and coexisting with garnet.

This research gives objective and reasonable explanation on metallization mechanism of Laochang Mo-deposit, and provide example for Cenozoic porphyry-skarn system in Sanjiang Tethys. Key words: Laochang /

2023年7月12日 · Swedish geologists initially coined the term “skarn” to refer to a green, calcic siliceous rock mainly composed of minerals such as garnet, pyroxene, hornblende, feldspar and epidote. The process of skarn mineralization is frequently linked with the concentration of metallic elements, leading to the formation of skarn-type deposits [1, 2].

2020年11月17日 · The Zhuxiling W (Mo) deposit in the district is dominated by skarn tungsten mineralization. This paper conducted in suit EPMA and LA-ICPMS spot and mapping analysis of the skarn mineral garnet to reveal the evolution of fluids, metasomatic dynamics, and formation conditions of skarn.

1992年12月12日 · Seven major classes of skarn deposits (Fe, W, Au, Cu, Zn, Mo and Sn) are briefly described, and relevant geological and geochemical features of important examples are summarized in a...

127 between 1975-1979, and led to the discovery of concealed Mo and Fe skarn orebodies at the 128 contacts between the dioritic intrusion and carbonate rock in the Xiaojiayingzi ore block (Figs, 2, 129 3a), and yieldeda resource of 0.11 Mt Mo at an average grade of 0.23 wt. % and 8.87 Mt Fe at an 130 average grade of 33.4 wt. % (Gao et al., 1979).
