摘　　要：文中通过分析文康地区的地质构造、地层、岩浆岩和矿床经典案例,可了解到本地区具有较好的成矿条件,特别是具备发展成为大剪切带状金矿的条件,另外在找矿时应尤其重视C-Si泥岩中韧性剪切带发育以及伴随破碎蚀变及低温元素组合的Au-As-Sb-Hg-Ag浓密分布区。Through the analysis of the classical cases of geological structure, strata, magmatic rocks and deposits in Wenkang area, it can be seen that the area has good metallogenic conditions, especially the conditions for developing into large shear zone-like gold deposits. In addition, the development of ductile shear zone in C-Si mudstone and the dense distribution area of U-As-Sb-Hg-Ag accompanied by fragmentation and alteration and low temperature element assemblage should be paid special attention to in prospecting.
