摘　　要：黑龙江省嫩江市播根里金矿矿体呈似层状、脉状赋存于北东向韧性剪切带中,近矿围岩为花岗质糜棱岩,或糜棱岩化正长花岗岩。矿化蚀变主要表现为强烈硅化、黄铁矿化,矿床成矿类型为韧性剪切带控制的热液蚀变型金矿,花岗岩体中的构造糜棱岩带,以及明显的硅化、黄铁矿化、等矿化蚀变是重要的找矿标志。The orebody of Bogenli Au deposit in Nenjiang,Heilongjiang is stratoid,veined in the NE ductile shear zone.The wall rock near orebody is granite mylonite or mylonitized syenogranite.The main metallogenesis alteration includes the silicification,pyritization.It is a hydrothermal alteration Au deposit controlled by ductile shear zone in genesis.The important prospecting criteria are the structure mylonite zone in granite,and clear silicification,pyritization,etc.
