    摘要:

    研究目的】通过箭猪坡锑多金属矿综合信息找矿模型的研究,对于进一步开展深部矿体定位预测具有重要意义。【研究方法】本文基于箭猪坡矿床锑多金属矿找矿工作,研究了深部成矿模式,分析了可控源音频大地电磁测深(CSAMT)、瞬变电磁测量(TEM)、地电化学测量等方法在深部找矿中的作用和效果。【研究结果】可控源测量能反映深部断裂带的延深情况,瞬变电磁测量低电阻率能有效识别矿化带或控矿断裂带,地电化学测量Pb、Zn、Sb元素变化曲线峰值能指示矿化体的存在。【结论】箭猪坡锑多金属矿地质-物探-化探测量综合信息找矿模型的建立为五圩地区深部找矿提供了可以识别的探测目标,CSAMT、TEM及地电化学测量综合方法能探测控矿断裂的深部特征,综合信息特征的找矿方法是构造控矿的有效技术手段。
    创新点:采用地质-物探-化探综合找矿方法构建多源信息找矿模型,预测深部矿体的位置、规模。

    Abstract:

    This paper is the result of mineral exploration engineering
    [Objective]Through the comprehensive information prospecting model of Jianzhupo antimony polymetallic deposit, it is of great significance to further develop the location prediction of deep ore body.
    [Methods]Based on the prospecting work of antimony polymetallic ore in Jianzhupo deposit, this paper studies the deep metallogenic model and analyzes the role and effect of controlled source audio frequency magnetotelluric sounding (CSAMT), transient electromagnetic survey (TEM), geoelectrochemical survey and other methods in deep prospecting.
    [Results]Controlled source measurement can reflect the depth of the deep fault zone, transient electromagnetic measurement with low resistivity can effectively identify the mineralized zone or ore-controlled fault zone, and geoelectrochemical measurement of Pb, Zn, Sb elements change curve peak can indicate the existence of mineralized bodies.
    [Conclusions]Hedgehog slope antimony polymetallic geological and geophysical-geochemical measurement with the establishment of a comprehensive information prospecting model for five fair in deep prospecting provides the detection of target can be recognized, CSAMT, TEM and electrochemical measurement synthesis method can detect deep characteristics of orecontrolling fracture, characteristics of comprehensive information prospecting method is an effective technical means of construction controlling.
    Highlights: A multi-source information prospecting model is established by using the comprehensive prospecting method of geology-geophysical and geochemical exploration to predict the location and size of deep ore bodies.
