摘要:

韧性剪切带内产生的次级断裂为金矿成矿提供了有利场所,剪切带内的裂隙是Au元素富集成矿的有利部位,这些次级断裂与围岩有较明显的电性差异,因此,可以利用精细物探方法寻找这些次级构造,为地质找矿提供依据。内蒙古苏尼特左旗巴润萨拉韧性剪切带西段的巴彦温多尔金矿的产出与韧性剪切带密切相关,通过Sting-Swift R1高密度电法仪对此矿区勘查应用结果显示:矿脉具有低阻高极化的物性特征,并且异常范围较小。研究表明,Sting-Swift R1高密度电法仪在与韧性剪切带有关的金矿床中寻找较小规模的矿脉是有效的。

Abstract:

Secondary faults that produced in ductile shear zone provided favorable places for gold mineralization. Fractures inner shear zone were the favorable position for the concentration and mineralization of gold element.There were obvious electricity differences between the secondary faults and wall rock.So it is possible to find the secondary structures by high precision geophysical method,and to provide a reference for geological prospecting. The occurrence of Bayanwenduoer gold deposit in Barun Sarah ductile shear zone western part in Sunitezuoqi of Inner Mongolia had close relationship with ductile shear zone.The results that applied Sting-Swift R1 electrical-resistivity system on the mining area showed that the lode presences the low resistance and high polarization with small range of anomaly.It is effective to find small scale ore vein of gold deposit that associated with ductile shear zone by Sting-Swift R1 electrical-resistivity system.

Key words: Ductile shear zone, Gold deposit, Electrical-resistivity system, Inner Mongolia
