Boneng砂锡矿区Ⅰ、Ⅲ区属残坡积型,Ⅱ、Ⅳ区属冲洪积型.前者分布于山麓及其缓坡地带,矿层较厚,品位变化大;后者分布于现代河床及两侧,规模不大,厚度l-10米,品位变化较大.一般情况下,在残坡积层中铁锰结核以及褐铁矿含量越高,锡的品位越高.
Geological Characteristics and Genetic Analysis of Boneng Tin deposit in Laos
The Boneng sand tin mining area belongs to the residual slope type in areas Ⅰ and Ⅲ,while areas Ⅱ and Ⅳ belong to the alluvial-proluvial type.The former is distributed in the foothills and gentle slopes,with thick ore layers and significant changes in grade;The latter is distributed in modern river beds and on both sides,with a small scale,a thickness of 1-10 meters,and significant changes in grade.In general,the higher the content of iron manganese nodules and limonite in the residual slope layer,the higher the grade of tin.
