摘要：

运用可控源音频大地电磁法、频谱激电法和高精度磁法等多种物探方法，在河南省西部多金属成矿带上进行深部隐伏金属矿体勘查。研究表明，利用CSAMT方法进行隐伏岩体的确定，再利用SIP法对目标体埋深进行具体定位，确定其含矿性，对于指导该区隐伏矿找矿具有重要作用。利用CSAMT方法在该区共圈定隐伏岩体2个，其走向NW，并向NE倾伏；运用SIP法在2号剖面进行实测，发现了双峰异常特征，认为该处可能有金属硫化物富集，与CSAMT测深推断的断层破碎带相吻合，由分析可知，该金属硫化物呈浸染状。由于开采埋藏较深的隐伏矿体风险较大，采用多种物探方法进行综合调查可以降低风险，减少物探勘查的多解性，提高地质解释的可信度和准确度。

Abstract:

The exploration of deep concealed ore-like metal within polymetallic mineralization belt in western part of Henan Province was conducted by using comprehensive geophysical prospecting methods of CSAMT，SIP and high-precision magnetic.The results show that it is useful for the concealed ore prospecting in the area by using the CSAMT method to determine the concealed rock，then SIP method to define the specific buried depth of the target body and determine its ore potential.Two concealed rocks with towards of north-west and lateral trending of the north-east have been delineated by CSAMT method in the area.Two cross-section are measured by using the SIP method，and a bimodal abnormal characteristics is found.So we come to the conclusion that there may be metal sulfides enrichment in this area，which is coincided with the fault fracture zone inferred by CSAMT measured，and the analysis shows that the metal sulfide was disseminated.Since it takes risk of unburying deep concealed ore-body，using multiple geophysical methods in comprehensive survey can greatly reduce the risk，which can decrease interpretation ambiguity in geophysical exploration，improve the credibility and accuracy of geological interpretation.
