Geological features and genesis of bauxite deposit in Danping, Guizhou province
摘要
Abstract
The bauxite deposit in Danping,located at the Zheng'an bauxite belt,is in the northern part of central Guizhou-southern Chongqing metallogenic belt,an important mineralization with good mineralization conditions.The geological characteristics,ore-controlling factors,mineralization enrichment rules and prospecting criteria of the deposit are analyzed,and the genesis of the deposit is discussed.The results show that it is a sedimentary deposit.Its metallogenic material mainly comes from the mud shale of ore-bearing rock series (Dazhuyuan Formation) sedimentary basement Hanjiadian Group.The bauxite deposit in Danping is a large deposit rich in gallium,estimating resource of 22.289 1 million tons,which is a large bauxite deposit.Among the ore body,the type of low iron high sulfur occupies first place,low iron low sulfur comes second.The main ore is clastic type,then half an earthy,oolitic and massive compacted.All of ore bodies are distributed in the middle-upper part of Dazhuyuan Formation of Middle Permian,which is the most intuitive and important ore-controlling factors in study area.It is also the main criteria and basis of bauxite deposit prospecting and exploitation in this area.关键词
