摘　　要：赣南崇义瓦窑坑-天井窝钨锡矿形成于燕山期花岗岩与奥陶系古亭组碳酸盐岩接触带上,沿着砂页岩与灰岩的层间发育的似层状矽卡岩型白钨矿矿床。通过勘查及钻探查明,瓦窑坑-天井窝矽卡岩体呈北东向,与控矿断裂平行,多组断裂为北北东向、北东向、北西向。结合区域地质背景综合分析认为,该矿床与区内褶皱、为裂关系密切。矿区地层褶皱形成倾斜背斜,层间滑动破裂,形成北北东向的逆断层,岩浆沿断裂裂隙侵入形成矽卡岩型白钨矿床。对矿区断裂、地层、岩体及成矿进行研究,对该区找矿具有指导意义。The Wayaokeng-Tianjingwo W-Sn deposit in southern Jiangxi is a stratoid skarn type scheelite-Sn deposit and occurs in the contact zone between the Yanshanian granite and the carbonate rock of the Ordovician Guting Formation.The skarn is NE-trending,parallel to the ore-controlling faults.The deposit is in close relationship with folds and faults.The ore-formation was related to magmatic intrusion along fault and fissures.The study of stratigraphy,fault,igneous rock and metallogeny is of importance to the prospecting in this region.
