摘要/Abstract

摘要： 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。

关键词: 天生桥矿区, 铝土矿, 成矿规律, 远景预测

Abstract: This paper analyzes Tianshengqiao bauxite deposit’s ore-hosting sequence,concludes that the structure types comprises of mud crystal,oolitic mud crystal and debris ores.Sedimentary environment plays a key role in bauxite distribution,which mainly occurs in subtidal zone and lagoon.Bauxite mineralization is also controlled by the bed of ore-bearing sequence and ancient karst terrain change.This paper,through drawing bauxite grade contour to determine the prospecting area with potential,provides reference for bauxite exploration and development and guarantees a Sustainable supply of bauxite ores from national strategy.

Key words: Tianshengqiao deposit, bauxite, mineralization rule, prospect prediction
