摘要:
古岩溶地貌控制着铝土矿体的形态和规模，对矿产勘查过程中工程布置意义重大。为了分析小院地区古地貌对铝土矿分布的影响，利用小院地区铝土矿区的钻探、测试资料，以及摆佐组+九架炉组（C1
b +jj ）厚度、摆佐组（C1b ）厚度恢复了九架炉组沉积前后的古地貌特征。结果表明：铝土矿体沿古地貌降低的方向间隔分布，单个矿体的形态受控于洼地、凹陷等具体形状；沿古地貌降低方向上，局部地形较低洼处是铝土矿体形成的有利区域；预测了茶园、十字2个铝土矿找矿远景区。研究成果为后续铝土矿资源勘查提供了参考。Abstract:Ancient karst landforms play a key role in controlling the shape and scale of bauxite deposits, which is of great significance for the planning of engineering layouts in mineral exploration.
Objective This study aims to analyze the impact of ancient landforms in Xiaoyuan area on the distribution of bauxite deposits.
Methods This paper utilizes drilling and testing data from Xiaoyuan bauxite mining area, and employs the thickness of the Paizuo Formation and Jiujialu Formation (C1
b +jj ) and the thickness of the Paizuo Formation (C1b ) to reconstruct the paleogeomorphic features of the Jiujialu Formation before and after sedimentation.Results The results show that the bauxite ore bodies are distributed intermittently along the direction of decreasing paleolandform elevation, and the morphology of individual ore bodies is controlled by specific geomorphic features such as depressions and sinkholes. Along the descending gradient of ancient landforms, locally low-lying areas are favorable sites for the formation of bauxite deposits. Two prospective bauxite mining target areas (Chayuan and Shizi) were predicted.
Conclusion The research results provide a reference for the exploration of bauxite resources.
