陕西李家沟金矿床的控矿条件

The Condition of Controlling Gold Deposit in the Li Jia Gou of Shanxi

近东西弧形压扭性断裂F2 为主干断裂 ,是矿床的控矿构造 ,并严格控制着矿体的分布 ,在入字型排列的构造相交部位为矿液上涌的良好通道和容矿场所 .探讨了控矿构造形迹的力学性质及相互关系 。

The approximately west east arc fault(F\-2) is the main fault which was caused by pressure and contortion The fault is the controlling ore texture The fault strictly controls the disribution of deposit The spot where the texture interlaces is good for ore fluid gushing and is a good place for containing ore The mechanical propeties and the correlation of controlling ore texture, as well as the relation between ore formation and control ore factors, alteration of ambient rock are discussed
