黑龙江省掉冰湖矿区斑岩型钼矿地质特征及成因初探

GEOLOGY AND GENESIS OF THE PORPHYRY MOLYBDENUM DEPOSIT IN HEILONGJIANG PROVINCE

黑龙江省庆安县掉冰湖钼矿床位于铁力市二股营林所,处于小兴安岭-张广才岭多金属成矿带,翠宏山-二股成矿亚带内,西以逊克-铁力断裂为界,东临佳木斯地块.矿体主要以浸染状、细脉浸染状和脉状赋存于似斑状二长花岗岩岩体中,属于斑岩型钼矿.区内二长花岗岩可能具有多期成岩作用,为钼矿床的形成提供了物源和热源,其形成于碰撞造山环境.

The Diaobinghu molybdenum deposit is located in the Cuihongshan-Ergu metallogenic belt of Xiaoxinganling-Zhangguangcailing polymetallic metallogenic province,bounded by the Xunke-Tieli fault on the west and adjacent to Jiamusi massif on the east.The orebodies occur as mainly disseminated veinlet and veins hosted in porphyraceous monzogranite pluton,belonging to porphyry molybdenum type.The monzogranite in the region,which is formed in the collisional orogenic environment,likely with multi-stage diagenesis,provides material and heat sources for the formation of the molybdenum deposit.
