摘要

 The Yaogangxian tungsten polymetallic ore-field consisting of Yaogangxian tungsten deposit, Qingshanli lead-zinc deposit and Heshangtan scheelite deposit, is located in the central part of the Nanling metallogenic belt. Detailed field geological investigation shows that three deposits are rather close in space, occurrence of ore body and ore-control factors. It indicates that two kinds of tungsten mineralization were formed in the same period, and also highly anastomosed with Yaogangxian composite pluton in time and place, and are part of the second large-scale mineralization in Nanling. The δ³⁴S values of ore mineral (pyrite, sphalerite, molybdenite) from three deposits show variations from -1.8‰ to +1.4‰. The characteristics of spatiality, chronology and sulfur isotopes, together suggest these three deposits are different parts of the same magmatic ore-formation.
