W-Sb-Au mineralisation related to granite-porphyry intrusions along the Xuefeng uplifted belt, Western Hunan, China

摘要

The W-Sb-Au mineralisation along the Xuefeng belt is spatially and temporally related to Mesozoic Indosinian-Yanshanin magmatism. Evidence from S, H and O isotope measurements in pyrites and quartz, microprobe analyses of native gold and wall-rock analyses for Au and Sb testify the relationships between the W-Sb-Au mineralisation and magmatic processes.
