摘要
小塔子沟金矿区出露于建平群小塔子沟组变质岩中。找矿矿物学研究表明，黄铁矿－黄铜矿－辰砂－白钨矿型矿石矿物组合。黄铁矿品位≥５０×１０￣（－６）、黄铜矿品位≥１×１０￣（－６）、自然金含量＞２粒等矿物组合标型，可作为该区找金的矿物学标志。
Xiaotazigou gold deposit emerged from metamophic rock from Xiaotazigou Tormation ofJianping Group. Studies on the exploration minerology show that pyritechalcopyritecinnabar-scheelite dineral assemblage,the grade of pyrite≥50 × 10￣(-6),the grade of chalcopyrite≥1 ×10￣(-6),and the contents of gold>2 grains can be used as the criteria for gold depositprespecting.
