摘    要:文章简要介绍了务-正-道地区铝土矿的成矿地质背景和务川瓦厂坪铝土矿床的地质特征.重点从含矿层位下二叠统梁山组地层的分布、厚度变化;构造运动控制务-正-道地区古地理的变迁;褶皱构造控矿等几方面分析了与铝土矿成矿的关系,进而又对比了省内各铝土矿集区找矿勘探工作程度,综合分析了该区的找矿勘探潜力.认为务-正-道地区应存在大中型规模的铝土矿床,中下志留统韩家店组之上的不整合面,下二叠统梁山组和向斜构造是其成矿的主要控矿因素.

关 键 词:铝土矿  务-正-道  不整合面  梁山组地层  构造运动

Abstract:Geological background of aluminum mineralization in the Wuchuan - Zhengan - Daozhen area and geological features of Wachangping aluminum deposit of Wuchuan are introduced. This paper mainly analyzes aluminum genesis with distribution and thickness variation of aluminum - bearing Permian Liangshan formation, paleo - geography changes in the Wuchuan - Zbengan - Daozhen area controlled by tectonic movement, and folding structure controlling ores. Ore - finding and exploration levels in the different aluminum ore regions have been compared and exploration potential in the area been analyzed. It is concluded that Wuchuan - Zbengan - Daozhen area should exist big or middle scale aluminum deposit. Main ore - controlling factors are unconformity between middle and lower Silurian Hanjiadian formation, and syncline in the upper Permian Liangshan formation.
Keywords:aluminum ore   wuchuan - zhengan - daozhen area   unconformity   Liangshan formation   tectonic movement
