文章通过对滇东南文山县天生桥矿区的含矿岩系特征分析,认为研究区铝土矿的结构类型主要包括泥晶结构铝质岩、鲕粒泥晶结构铝质岩和粒屑结构铝质岩3种类型。沉积环境是控制铝土矿分布的主要因素之一,区内铝土矿主要赋存于潮下带和泻湖区域,此外,该地区的成矿作用还受到含矿岩系层位和古喀斯特地形、地貌的变化所控制。通过编绘研究区铝土矿最高品位和平均品位等值线图圈定成矿有利远景区,为铝土矿资源开发勘探前景提供有利数据支持,从国家战略层面保证铝土矿的可持续供应。
Based on the analysis of the characteristics of the ore-bearing rocks in the Tianshengqiao Mine Area, Wenshan County, southeast Yunnan, the authors believe that the structural types of the bauxite in the study area mainly include the algidite structure of algidite, 3 types. Sedimentary environment is one of the main factors controlling the distribution of bauxite. The bauxite in the area mainly occurs in the subtidal zone and lagoon area. In addition, the metallogenesis in this area is also affected by the ore-bearing strata and the ancient karst topography , Changes in landscape control. By mapping the highest grades of bauxite in the study area and contour maps of average grades, favorable prospecting areas were delineated, which provided favorable data support for exploration prospect of bauxite resources and guaranteed the sustainable supply of bauxite from the national strategic level.
