摘　　要：敖仑花斑岩钼铜矿床位于大兴安岭南段,是西拉木伦河断裂北侧成矿带新发现的大型斑岩型钼铜矿床,敖仑花铜钼矿主要赋存于斜长花岗斑岩中,硅化、钾长石化、黄铁矿化等蚀变发育,并具有明显的分带特征,石英网脉极为发育,网脉的密度可指示矿化作用的强度。本文在分析矿床的成矿地质背景、矿床的地质、地球物理和地球化学特征,从横向和垂向上测量石英网脉密度的变化规律以及蚀变分带规律的基础上,总结矿床的找矿标志,指导成矿预测。Located in the southern Da Hinggan Mountains,north of the Xilamulun polymetallic belt,Aolunhua Cu-Mo deposit is a newly found porphyry molybdenum copper deposit.The Cu-Mo deposit mainly occurs in plagioclase granite porphyry,silicification,K-feldspar of pyrite alteration of such development and has a clear zoning characteristics.Quartz stockwork is well developed and the density of the stockwork can be used to measure the intensity of the mineralization.This paper analyzes the geological background of the mineralization,as well as the geological,geophysical and geochemical characteristics of the deposit.By means of measurement of the variation of the horizontal and vertical density of quartz stockwork and alteration zoning changes,this sutdy summarizes the prospecting critiria to guide the metallogenic prediction.
