中文摘要:
      [摘要]本文通过地球电化学、次生晕、电吸附、土壤离子电导率、土壤吸附相态汞多种新方法在已 知矿体上方异常特征,再结合地质分析矿体上方的异常,最终提取有用的多元信息为电提取、土壤离子 电导率和土壤吸附相态汞异常,且它们异常必须共生。在土壤离子电导率异常和土壤吸附相态汞范围 内或旁侧(与电导率异常局部重叠吻合),出现明显的As、Sb、Ag 等地电提取的峰值明显的离子异常,唯 这些离子异常比电导率异常和土壤吸附相态汞异常幅度窄一些。
英文摘要:
      Abstract:The Qiagong Iron deposit is a newly discovered deposit, but geometric characteristics of its ore body such as the shape, size, position, oc2 currence and boundary have not been fully tested. Based on awavelet andmulti - scale analysis and Euler deconvolutionmethod, the vertical signal of po2 tential field is separated and the sources dep th is estimated. The twomethodsmentioned above are jointly used to detect themagnetic source dep ths, which could p lay an important role in locating the deep - buried orebodies.
