阳山金矿带位于西秦岭南亚带,区内构造复杂,断裂发育较多。安坝断裂带的岩性主要为含炭泥质千枚岩、蚀变斜长花岗斑岩、砾岩、灰岩,而断裂带内的填充物主要为碎裂岩、构造砾岩组成,它们在电性方面表现为低电阻率,为开展高密度电法、瞬变电磁法的开展提供了先决条件。运用该方法结合地质观察,通过断裂带上的某剖面进行解释,最终经钻孔验证,对该区的断裂的勘探具有较好的效果,为下一步的工作提供了较好的指导。
暘山金礦帶位于西秦嶺南亞帶,區內構造複雜,斷裂髮育較多。安壩斷裂帶的巖性主要為含炭泥質韆枚巖、蝕變斜長花崗斑巖、礫巖、灰巖,而斷裂帶內的填充物主要為碎裂巖、構造礫巖組成,它們在電性方麵錶現為低電阻率,為開展高密度電法、瞬變電磁法的開展提供瞭先決條件。運用該方法結閤地質觀察,通過斷裂帶上的某剖麵進行解釋,最終經鑽孔驗證,對該區的斷裂的勘探具有較好的效果,為下一步的工作提供瞭較好的指導。

The Yangshan gold ore belt lies in the south zone of West Qinling Mountains where structure is very complicated with development of faults. The Anba fracture is composed of carbonaceous phyllite, altered granite porphyry, limestone, conglomerate with infilling of cataclasite and tectonic breccia. They are characterized by low resistivity in conductive property which provides the possibility for Multi-channel resistivity method and TEM. This paper deals with the application of multi-channel resistivity method and TEM to the Yangshan Au deposit.
