摘　　要：范疙瘩金矿位于熊耳山断隆的东南部,马超营断裂带的北侧,金矿体产于北西向M14断裂带内。本文通过研究断裂构造的方向、规模、分布特征,分析断裂活动历史及矿体产出特征,总结成矿规律。金矿体严格受M14断裂控制,离断裂越远金矿化越弱,M14断裂带倾向上引张部位及断裂分支复合部位是金元素的富集地段,是成矿有利部位。Fangeda gold deposit lies in the southeastern part of the Xiongershan fault upwarpmg ana m the north to the Machaoying faulted zone. The ore bodies of the deposit are occurred in the NW-trending M14 faulted zone. By researching the strike, scale, distribution of the faulted zone and analyzing the activity history of the faulted zone as well as occurrence features of gold ore bodies ,we summarize the metallogenetic regularities of the deposit and point out that the gold ore bodies are controlled strictly by the M14 faulted zone, the farther to the faulted zone the weaker gold mineralization. The stretch and junction sections of branch faults on the dip of M14 faulted zone are the sites enriched with gold element ,where are favorable to gold mineralization,
