我们对三九○、三九五两个地区,作了γ资料的趋势面分析,并对趋势高及趋势鞍部进行了适当的深部揭露验证工作,现就所获得的结果分别加以介绍。一、三九○地区该区位于灵山岩体西段,为燕山早期花岗闪长岩(γ_5~2)和晚期黑云母花岗岩(γ_5~3)。脉岩以石英脉和细晶岩脉为主,细粒花岗岩脉、煌斑岩脉次之。断裂构造分近南北向、近东 We conducted a trend surface analysis of the γ data in the areas of 390 and 3955 and conducted proper deep disclosure verification of the trends and trends in the saddle areas. The results obtained are now separately introduced. 399 Area The area is located in the western section of the Lingshan Rock mass, which is the early Yanshan granodiorite (γ_5 ~ 2) and the late biotite granite (γ_5 ~ 3). Quartz veins and quartz veins quartz vein, fine granite veins, lamprophyre vein followed. Fracture structure near North-South, near East
