贵州省福泉市英坪磷矿矿石特征及成因分析
|
摘要
根据前人研究成果及本次勘探工作,综合分析英坪磷矿矿床地质特征,为后期矿山开发利用提供参考。根据室内显微镜下磷矿石的结构构造,研究磷矿成因;根据区内磷矿石的自然类型,结合镜下特征,分析矿石中矿物共生组合关系;通过矿石中主要有益组分的分析,了解矿石中P2O5含量的变化规律;通过矿石中主要杂质组分含量与有益组分P2O5含量对比分析,认识各矿石自然类型的化学特性及变化规律;根据磷矿成因分析,初步认为磷矿石的结构构造是反映矿床沉积环境的重要标志,与矿床成因密切相关。
According to the previous research results and this exploration work,the paper has comprehensively summarized the geological characteristics of Yingping phosphate deposit in order to provide a reference for the deposit development and utilization in the future.Based on the structure and texture of phosphorus ore under microscope,the genesis of phosphate deposit is studied.According to the natural type of phosphorus ore in the mining area,the relationship of mineral symbiotic assemblage of the ore is analyzed with the combination of the microscope characteristics of the ores.On the analysis data of the main beneficial ore components,it is understood for the variation regularity of P2 O5 content of ore.On the comparative analysis of the content of main impurity ore components and the P2 O5 content of beneficial components,it is recognized for the chemical characteristics and variation regularity of the natural type of each ore type.According to the analysis of the genesis of phosphate rock,it is preliminarily believed that the structure and texture of phosphate rocks is an important indicator to reflect the sedimentary environment of the deposit,which is closely related to the genesis of the deposit.
