摘要/Abstract

摘要： 上思县平广林场那厘矿区熔剂用石灰岩矿位于十万大山复式向斜西部，上思盆地以北。通过分析矿区地质、矿体地质、控矿因素等，总结矿床地质特征及矿床成因。矿区圈出3 个石灰岩矿体，矿体规模大，厚度稳定，有益组分CaO 品位在54.21%~55.45%，品位较高且稳定，有害组分含量低。矿床主要形成于早中二叠世裂谷盆地内的孤立台地，该时期沉积的茅口组地层为石灰岩矿赋存层位，矿体展布主要受地层控制，次级褶皱及断裂造成地层的重复、缺失。

Abstract: The limestone mine for flux in the Nali mining area of Pingguang Forest Farm in Shangsi County is located in the west of the Shiwanda Mountain compound syncline and in the north of the Shangsi Basin. By analyzing the mining area geology，ore body geology，ore controlling factors，etc.，the geological characteristics of the ore deposit and the genesis of the ore deposit are summarized. Three limestone ore bodies are delineated in the mining area，the ore bodies are large in scale and stable in thickness. The de⁃ posit is mainly formed in the isolated platform in the Early-middle Permian rift basin. The strata of Maokou Formation deposited during this period are limestone deposits. The distribution of ore bodies is mainly con⁃ trolled by strata，and secondary folds and faults cause stratigraphic duplication and deletion.

Key words: limestone mine, deposit geology, ore genesis
