摘要
通过对蛇屋山金矿钻孔资料及浅井资料的深入研究，将松散层自上而下划分为硅帽、褐红色（含）砾（质）粘土、浅色网纹状粘土、棕灰－棕红色粘土、弱风化带等五个层位。金主要赋存于棕灰－棕红色粘土层以及浅色网纹状粘土层的下部。金矿的形成受制于基岩的含金性及第四纪的风化作用，属红土型金矿床。
Aecording to the data acquired from drill holes and shallow boied well in She-Wu Shan sold deposit,the looSe strain are found to consist of 5 beds, namely,siliceous cap, red-brown colored gravel clay,light colored and net-like clay, brown-gray/brown-red colored clay and weak weathered zone, denominated respectively from top to bottom of the strata. The gold dominantly occurs in the fourch bed and the bottom of the third one. The formation of the gold depositS was restrained by gold bearing property of basement rock as well as by quaternary weathering. ThiS deposit belong in redclay type.
