摘要
斑岩型铜钼矿床由于具有规模大、埋藏浅、易于开采的特点,成为铜、钼金属的主要来源,一直是地质找矿的主要方向,因此研究斑岩型铜、钼矿勘查找矿方法具有十分重要的意义。以鹿鸣钼矿(开展了详查和勘探工作的典型斑岩型矿床)为例,利用重磁、激电、高密度电阻率以及可控源音频大地电磁测深(Controlled Source Audi-frequency Magnetotelluric,CSAMT)等多种地球物理勘探方法,结合矿区矿体部位的矿床地质特征,系统分析了矿区物探异常特征,建立了矿区地质地球物理模型,并给出了寻找该类型矿床的地球物理勘查方法和实施步骤,为该地区以及类似地区的找矿工作提供参考。
The porphyry copper-molybdenum deposit is the main source of copper and molybdenum and the main direc-tion of geological prospecting due to its characteristics of large scale,shallow bury and easy exploitation. So,it has great signifi-cance to investigate the prospecting method of porphyry copper-molybdenum deposit. Taking the Luming molybdenum deposit （ the typical porphyry deposit for which the detailed survey and exploration work have been done） as the research object,vari-ous geophysical exploration methods including gravity and magnetic anomaly,induced polarization,high density resistivity and controlled source audio-frequency magnetotelluric （ CSAMT ） are adopted to systematically analyze the geophysical anomaly characteristics of the mining area,combining with the ore deposit geology characteristics of parts of the ore-body. The geological and geophysical model of mining area is established,and the geophysical exploration methods and implementation steps for see-king for this type of ore deposit are summarized. The above research results can provide some references for the prospecting work in the mining area and the similar areas.
