ANALYSIS OF SMALL STRUCTURE IN DAM SITE ENGINEERING GEOLOGIC INVESTIGATION ——As Exampled for Guandi Waterpower Station of Yalongjiang;
坝址工程地质勘察中的小构造解析——以雅砻江官地水电站为例
The primary ores of Guandi Ag Au deposit are obviously different from the oxidation ores in ore colors,mineral grain sizes and association as well as in the existing status of silver and gold,Therefore,the oxidation ores have to be separately mined and processed.
官地银金矿床的原生矿石和氧化矿石在矿石颜色、矿物粒度、矿物组合和银金赋存状态均有明显差异。
Guandi reservoir dam from the Yalong River bends itself to become a thin watershed of near south-east direction.
官地水库的库首由雅砻江自身河弯形成了一个近东西向的单薄分水岭,该分水岭南北方向上长仅1880m,沿南北向展布的石炭系—二叠系碳酸盐岩贯穿了水库内外,构成了潜在的库水外渗通道。
