摘要
侵入燕山早期二长花岗岩岩基的二长花岗斑岩体具面型蚀变分带特征,由内向外可划分为:石英-绢云母化带和泥化带。在石英-绢云母化带中,含钼石英细脉充填于较发育的网脉状裂隙内,构成厚板状、连续性好、产状稳定、矿石矿物组合简单、规模较大的钼矿体。
The monzonitic granite-porphyry that intruded into adamellite batholith in the early Yanshanian shows planar altered zoning character, from the inner to the outer, it can be divided to quartz-sericitization zone and argillation zone. In quartz sericitization zone, the fine quartz vein bearing Mo is filled in the developed net-veined fissures, which forms the thick- tabular, highly continuous, stable occurrence, simple ore, mineral assemblage, large size Mo orebody.
