摘要
研究区地壳演化分四个阶段:结晶基底形成阶段(Ar2-Pt1);板块多次俯冲碰撞和火山喷发阶段(Pt2~3);板块碰撞和岩浆侵入阶段(Pz);板块碰合与新构造运动阶段(Mz-Kz)。金矿床分布可分三条带:北带,金-镍-钴和金-黄铁矿带;中带,金-多金属矿带;南带,金-铜矿带。
The crustal evolution is divided into four stages: the forming of crystalline basement (Ar2-Pt1); multiple subduction and collision of plates and volcanic eruption (Pt2 ̄3); collision of plates and magmatic intrusion (Pz); collision and junction of plates and new tectogenesis period (Mz-Kz). The gold deposits can be divided into north zone: AuNi and Aupyrite zones; middle zone: Aupolymetallic zone and south zone: AuCu zone.
