黑龙江省鹿鸣钼矿地球物理特征及异常模型

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。

Geophysical Characteristics and Anomaly Model of the Luming Molybdenum Deposit in Heilongjiang Province

The porphyry copper-molybdenum deposit is the main source of copper and molybdenum and the main direction of geological prospecting due to its characteristics of large scale，shallow bury and easy exploitation.So，it has great significance 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，various 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 seeking 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.
