摘　　要：在第四系总厚度为 1 7m以上 ,由 1m左右直径的巨砾石层、亚砂土、黄粘土组成的巨厚冲洪积物之上发现有清晰的后生Au、Hg异常带 ,经工程验证 ,发现了其下埋藏的厚1 .6～ 8m ,Au品位最高达 1 0 3 .1 3×1 0 -6,一般为 (4～ 8)× 1 0 -6的金矿体。The Quaternary at the depth interval of 17 meters consists of huge gravels measuring about one meter in diameter, sub-sandy soil and yellow-clay sediment. Epigenetic anomaly of gold-mercury anomaly zone led to the discovery of gold orebodies with the thickness of \{1.6\}-\{8.0\} meters, Au contents from (4-8)×10\+\{-6\}, and the highest grade of \{103.13\}×10\+\{-6\}.
