摘    要:本文在讨论安康地区区域地质背景的基础上,对铀、钒、钡和金矿的成矿特征提出了认识。成矿物质来源主要来自碳硅质岩和基底火山岩,并经热液—构造强烈改造,多在风化带富集成矿。晚期脉岩和含碳岩系可作为找矿标志。本文还讨论了铀矿与钒、钡等元素之间的关系。

关 键 词:铀钒钡与金矿  成矿特征  含矿岩系  安康地区

Abstract:This paper deals with ore-forming characteristics of U,V,Ba and Au on the basis of discussion about geological setting of the Ankang region.It is considered that ore-forming material reeoncentrated within weathering belt was mainly derived from carbonaceous sili- calite and volcanic rock of basement,and was underwent intensively reformation by struc- ture-hydrothermal.The vein rock at later stage and carboniferous rock series can be used as an indicator for ore prospecting.Besides,the relationship of U relevant to V and Ba ele- ments and so on is discussed as well in the end of this paper.
Keywords:U  V and Ba relevant to Au  ore-forming characteristics ore-bearing rock series  Ankang region
