| 中文摘要: |
| 贵州开阳县为大型富磷产区，为进一步了解开阳磷矿特征并提供可靠的勘探方向，以期为矿产资源开发及矿山建设等提供基础依据，本文以开阳大坪磷矿床为研究对象，开展了地质特征、矿床成因、找矿预测等方面的相关研究。研究结果显示，区内磷矿石自然类型为致密状、条纹—条带状、碎屑状和团块状磷块岩。震旦系洋水组为研究区最主要的富磷层位，总体呈南厚北薄、西薄东厚特征，矿层整体厚度较大，品位高，连续性好，工业利用价值高。研究区矿层虽然埋深较大，但具有质优量大的资源优势。大坪磷矿床处于开阳地区成矿中心带的中部地段，向北、向东矿体未见尖灭，结合周边矿区的地质成果，综合分析认为，大坪磷矿区范围外，沿北东方向具有良好的找矿潜力，未来开采可能具有较大的经济价值。 |
| 英文摘要: |
| Kaiyang County of Guizhou Province is a large phosphorus rich area. The geological characteristics， genesis and prospecting prediction of Daping phosphate deposit in Kaiyang County are analyzed， which will help to further understand the characteristics of Kaiyang phosphate deposit and provide a reliable exploration direction in Kaiyang area， and provide a basis for mineral resources development and mine construction. The research results show that the natural types of phosphate rock in this area are dense， stripe-banded， clastic and massive phosphorite. The Sinian Yangshui Formation is the main phosphorus rich deposit in the study area， which is thick in the south and thin in the north， thin in the west and thick in the east， and the overall mineral layer is thick， high grade， good continuity and high industrial utilization value. Although the ore layer in the study area is buried deep， it has the resource advantage of high quality and large quantity. The Daping phosphate deposit is located in the middle part of the metallogenic center belt in Kaiyang area， and the ore bodies have not been pinnacled to the north or east. Combined with the geological results of the surrounding mining areas， the comprehensive analysis shows that there is a good prospecting potential in the northeast direction outside the scope of Daping phosphate deposit， and the future mining may have greater economic value. |
