摘要:
石岗寨金矿床赋存于新元古界红安岩群七角山岩组断裂中，北东向断裂为主要含矿构造，含矿构造倾向延深大于走向延长。矿体形态简单，呈脉状、透镜状，具有平行排列、尖灭再现的特征，厚度、品位变化较大，部分工业矿体由浅向深具有厚度变大、品位变富的趋势；黄铁矿为主要的载金矿物，金主要以裂隙金的形式赋存于黄铁矿中，矿石类型主要为构造蚀变岩型金矿石，硅化、黄铁绢英岩化、黄铁矿化与金矿化关系密切。根据矿体特征，结合矿区成矿条件，认为矿区深部具有进一步找矿的潜力。对ⅩⅥ、ⅩⅣ矿体进行了深部验证，发现了工业矿体。

Abstract:
Shigangzhai Gold Deposit occurs in the Neoproterozoic Hong’an Group Qijiaoshan Formation fault structure.The NE fault is the main ore-hosting structure that stretches longer in inclination than in striking.The ore body morphology is simple,taking the form of veins and lens and possessing the characteristics of parallel aligning and pinching out,with notable variation in thickness and grade,part of industrial ore bodies exhibiting the trend of expanding thickness and enriching grade;pyrite is the main gold-bearing mineral.Gold occurs in the pyrite in the form of fissure gold.The main ore type is structural alteration rock type gold ore.Silicification,beresitization and pyritization are closely related with gold mineralization.According to the ore body characteristics and district ore-forming conditions,it is deemed that the district bears further prospecting potentials deep inside.Verifications are conducted deep in ore body ⅩⅥ and ⅩⅣ and industrial ore bodies are found in there.
