激发极化法在大架金矿床中的应用效果

The application of induced polarization method in Dajia gold deposit

六批叶矿区大架金矿床与韧-脆性剪切带密切相关。文中根据矿化岩石与围岩间存在明显电性差异特征,选用激电中梯方法测量,结果表明:激电中梯方法在大架金矿床可直接发现金矿(化)体,并依据极化率、电阻率异常平剖面分布特征推断隐伏金矿(化)体。

The Dajia gold deposit of Liupiye ore district is closely related to the ductile-brittle shear belt. According to the notable electric difference between mineralized rock and wall rock, the induced polarization method is accepted. The resuit shows that the induced polarization method result can indicate the gold orebody or mineralized orebody, and the blind gold orebody or mineralized orebody can be deduced according to the exception features of distribution of polarizability and resistively.
