电法在内蒙灰山超基性岩型铜镍矿找矿中的应用研究
|
摘要
本文通过对国内外已知超基性岩型铜镍矿床地质特征的对比分析,着重研究内蒙灰山含矿超基性岩的地质特征,分析在内蒙灰山应用电法勘探的地质前提条件。在此基础上,首次将电阻率法和激电法应用到内蒙灰山超基性岩型铜镍矿床找矿中,取得了较好的找矿效果。
内蒙灰山超基性岩型铜镍矿勘探区的大地构造处于华北板块边缘,位于二连浩特一苏尼特左旗超基性岩铜镍成矿带,是内蒙铜镍矿的主要找矿潜力区之一。
本文通过对国内外已知超基性岩型铜镍矿床地质特征和地球物理标志特征的对比分析,研究了内蒙灰山含矿超基性岩的地质特征,分析在内蒙灰山应用电法勘探的地质前提条件。在通过高精度磁测圈定出超基性岩体的基础上,利用铜镍矿体与超基性岩体、蚀变带和硅质板岩之间的电阻率和电极化率差异,开展电阻率和激发极化两种方法,通过野外数据采集,室内数据处理和异常推断解译,得出内蒙灰山蚀变含矿超基性岩体铜镍矿化体(矿体)可能存在,以及可能存在的矿化体(矿体)的形态和规模,并确定出了矿化体(矿体)的大致埋藏深度,为布置钻探工程提供了依据。
In this paper, we had do the comparative analysis about the geological characteristics of ultrabasic rock-type Cu-Ni deposits both at home and abroad, especially in Huishan Neimeng and analysed the preconditions in applicating electrical prospecting in Huishan Neimeng. On this basis, resistivity and induced polarization method were applied in Huishan Neimeng in the first time, and achieved better results prospecting.
The tectonic of ultrabasic rock-type Cu-Ni mine exploration in Huishan Neimeng lies in plate boundaries in northern China ,locating Erlianhaote - Sunitezuoqi ultrabasic rocks with Cu-Ni mineralization,and is one of the main potential areas prospecting.
To contrastive study geological characteristics and geophysical characteristics of the known ultrabasic rock-type Cu-Ni sulfide deposit at home and abroad, this article studies the ore-bearing ultrabasic rock's geological features of Huishan and analysis the electrical prospecting geological preconditions. In the ultrabasic rock-type orebody, based on the differences of resistivity and polarizabilty of the ultrabasic rockbody, alteration zone and silicon slate, carrird out induced polarization method and resistivity method.Through field data collection, data processing and data interpretation ,we included that altered ore-bearing ultrabasic rock may exist, as well as the shape and size of rockbody and determined the approximate depth of burial.at last provided the basis for the drilling engineering.
