Abstract

In order to ascertain the deep geological tectonic frame in key mineralization areas of Anba ore section in Yangshan gold deposit belt, and guide the layout of census work and metallogenic zone, the authors in this paper used V8 electrical law workstation to detect Controlled Source Audio-frequency Magneto-telluric (CSAMT) in key mineralization areas of Anba ore section. Comparing the results with existing drilling profiles, the deep conductive structure in Anba ore section is preliminarily defined as anticlinal structure of NEE direction with a plunge of east direction. The shallow tectonic fractured belt is identified as an advantage point, and transition belt with characteristics of abnormal high and low apparent resistivity is supposed to be geophysical prospecting direction. And the CSAMT is proven to be enforceable in detecting ore-controlling structures characteristics, which is the auxiliary approach in prospecting and has guidance effect on polymetallic mineral exploration in complex landform.
- Yangshan gold deposit,
- apparent resistivity,
- CSAMT,
- anticline structure,
