摘要
The bauxite deposit in the Kaili area is of the sedimentary type which formed on the eroded surface of carbonate.This area underwent many times of crustal movement during the geological history.Based on geologic and ore-forming background and bauxite deposit characteristics,this paper analyses the main ore-controlling factors of the formation process.It is suggested that the process can be roughly divided into three phases:the material forming phase,the deposition and preservation phase and the secondary enrichment phase.
