| 摘 要： | 虽然传统物探方法在大多数金属矿产勘查中都取得了良好的效果，但在锰矿勘查中的应用却相对较少，这主要是由于锰矿与其围岩的地球物理性质和化学性质差异较小，加大了锰矿的勘探难度，尤其是埋深较大、后期改造强烈的一些锰矿床，勘探难度更大，导致进行直接找矿效果并不显著。笔者近几年主要在巴山锰矿带和塔里木盆地西南缘锰多金属矿区采用不同的物探方法进行锰矿勘查工作，在部分矿区取得了较好的勘查效果。本文主要以塔里木盆地西南缘锰多金属矿区的新疆奥尔托喀讷什一带锰矿区为例，主要介绍了采用激发极化法在该工区开展的具体工作情况以及取得的一些成果认识，表明该方法在寻找隐伏含锰层位具有较好的效果。

| Abstract: | Although traditional geophysical technology has achieved good results in exploration of most metal minerals, its application to surveys of manganese ore remains relatively little. The reason is the small differences of geophysical and chemical properties between manganese ore and surrounding rock. In particular, some manganese deposits with deep burial depth and strong reconstruction in later periods are more difficult to explore, resulting in poor direct prospecting effect. In recent years, we have used different geophysical methods to conduct manganese ore exploration in the Bashan manganese ore belt and the manganese polymetallic ore district in the southwestern margin of the Tarim basin. In some mining areas, good exploration results have been achieved. This paper takes the manganese ore district around Ortokanesh, Xinjiang as an example to present the specific work by the induced polarization (IP) method, some results of exploration and new insights, which show that the IP method can be successfully applied to searching for hidden manganese ore beds. |
