The ore - forming material is mostly from volcanic rock , and sub volcanic rock provides the main thermal and some mineral materials . the ore - forming fluid is from meteoric water . as a result , it should be a kind of adularia - sericite type of epithermal gold deposit 成矿物质主要来自矿区火山岩围岩，次火山岩提供了主要热源和部分矿源，成矿流体来自大气降水，矿床成因类型为低硫化物冰长石?绢云母型浅成低温热液型金矿。

The metallic mineral has very few content ( 1 % - 2 % ) , the mineral of ore is mainly of pyrite , chalcopyrite , limonite , aurum and electrum etc . the gangue mineral is composed of chalcedony , micro grained quartz , calsite , sericite , adularia , aragonite , chlorite , laumontite , pyrophyuite , kaolinite and so on , which show the typical mineral assemblage of epithermal 矿石为典型少硫化物型，金属矿物含量极少( 1 - 2 ) ，主要有黄铁矿、黄铜矿、褐铁矿和自然金、银金矿等。主要脉石矿物有玉髓、微粒石英以及方解石、绢云母、冰长石、文石、绿泥石、浊沸石、叶腊石、高岭石等，属典型低温矿物组合。
