摘　　要：通过在安徽无为西湾地区大量的物探工作,综合物化探及钻探等勘查手段,在庐枞盆地北东缘发现了大型隐伏铅锌矿床。在前人工作的基础上,对西湾铅锌矿16勘探线进行了可控源音频大地电磁测深(CSAMT)和大功率时间域激电测深(TDIP)方法试验,通过数据处理解释与研究,推断含矿有利部位,结合已有钻孔和激电测井数据进行检验,证明在覆盖区找矿工作中可控源音频大地电磁测深和时间域激电测深两种方法组合具有较好的效果。Based on extensive geophysical exploration in Xiwan area,Wuwei City,Anhui Province,a large concealed Pb-Zn deposit was discovered in the northeast margin of the Lujiang Basin by means of geophysical and geochemical exploration and drilling.On the basis of previous work,controlled source audio-frequency magnetotelluric(CSAMT)sounding and high-power time domain induced polarization(TDIP)tests have been carried out on the exploration line 16 of the Xiwan lead-zinc deposit.Through data processing,interpretation and in-depth study,favorable ore-bearing positions have been inferred,which has been tested with the existing boreholes and IP logging data.It is proved that the combination of controlled source audio-frequency magnetotelluric sounding and time domain induced polarization sounding has good effect in ore prospecting in the covered area.
