摘　　要：纳相—秧坝地区位于贞丰县烂泥沟金矿床和丫他、板其中型金矿床之间,处于兴义隆起与右江裂谷-前陆盆地两构造单元交界处,具有相同的区域成矿边界条件,矿床地质特征相似,具有Au、Sb、As、Hg土壤地球化学综合异常,岩石地球化学测量反映Hg、F、Sb具前缘晕特征;物探测量反映在T_2xm^4之下存在隐伏背斜。推测在T_2xm^4/T_2xm^3构造界面上,特别是在隐伏背斜轴部,具有较好的成矿条件,具有找矿远景。Naxiang-Yangba area located between Lannigou gold deposit and Yata,Banqi gold deposit,the juncture of Xingyi uplift and Youjiang valley-foreland basin,they have the same regional metallogenic boundary conditions,the deposit geological features are similar,has soil geochemical anomaly of Au,Sb,As and Hg,the rock geochemistry test shows the front holo features of Hg,F and Sb,the geophysical prospecting shows conceal anticline under T2xm^4. It＇s inferred has good metallogenic condition on the T2xm^4/ T2xm^3,especially the axis position of conceal anticline,has good exploration prospecting.
