Indium (In) is commonly hosted in Sn-rich deposits but rarely reported in Sn-poor deposits. However, an In-rich and Sn-poor skarn deposit, the Qibaoshan Cu-Zn-Pb deposit, has been identified in south China. Geochemical analyses were undertaken on 23 samples representing the following mineral assemblages: sphalerite-pyrite, pyrite-chalcopyrite, pyrite-sphalerite-galena-chalcopyrite, pyrite, magn...

• Geochronology and petrogenesis of the ore-forming intrusions from Lietinggang-Leqingla deposit. Fe-Cu mineralization was controlled by mantle materials weakly fractional crystallization. An ancient crustal component extensive fractionation crystallization contributed to Pb-Zn mineralization. The deposit has magmatism conditions that allow iron-copper lead-zinc form simultaneously. is a repres...

Prospectivity modelling has been completed over the Lachlan Fold Belt, New South Wales, Australia, using the GIS based weights of evidence modelling technique to target porphyry Cu-Au, associated skarn Cu-Au, orogenic Au and VMS Au mineralisation. The Lachlan Fold Belt is a 700 km wide belt of Paleozoic accretionary terrains, stretching from Queensland to Tasmania. Porphyry and skarn mineralisa...

Garnet is the most common alteration mineral in skarn-type deposits, and geochronological research on it can limit mineralization age. The Longwan Pb–Zn deposit, situated within Fozichong ore field Guangxi, lacks precise data, limiting in-depth comprehension of its genesis tectonic setting. This study employs LA-ICP-MS U–Pb dating garnets developed skarn orebody zircons associated granitic porp...

Application of an X-ray fluorescence (XRF) microprobe for the analysis of single grains (80 to 1,000 m in diameter) of Clrich minerals for Br has been evaluated for fluorapatite, chlorapatite, scapolite-group minerals (marialite and meonite) and sodalite. A calibration curve based on the Br contents in four international reference materials has been confirmed by measurements on Brbearing standa...
