摘要
内蒙古老硐沟金矿床成因类型问题长期以来一直具有争议,主要存在内生矿床与外生矿床2种不同认识。经过对前人资料进行总结分析并通过多次野外和井下坑道调查,论述了老硐沟金矿床的地质特征、控矿因素和成因类型,提出老硐沟金矿属于内生热液蚀变型金矿床,而不应称之为氧化淋滤型金矿床,深部原生矿同样具有较大成矿潜力和找矿前景,这一认识将对该地区今后的深部探矿工作起到指导作用。
The genetic types of Laodonggou gold deposit have been controversial for a long time in Ejin Banner, Inner Mongolia, and there are two main points of contention, endogenous deposit and exogenous deposit.Through the analysis of the previous data and field and underground tunnel survey,this paper discusses the geological features, ore-controlling factors and genetic types of Laodonggou gold deposit.We consider that Laodonggou gold deposit belongs to the endogenetic hydrothermal alteration type gold deposit.It should not be called an oxidizing- leaching type gold deposit.It is suggested that there are large potentials to find new gold ore bodies in the deep.
