摘要: 寻甸没租哨大型磷矿床的勘探发现与近年业界新突破的“云南省镇雄县羊场–芒部地区磷矿”超大型矿床共同进一步验证了区域磷矿带向NE延展的分布规律，为区域寻找隐伏磷矿床呈现了空间和方向。本文运用“勘查区找矿预测理论与方法”进行典型矿床研究。从北至南形成硝滩–羊场、九龙–会泽、昆明–华宁三大聚磷盆地典型矿床，分别以镇雄县羊场磷矿、寻甸县没租哨磷矿、晋宁县昆阳磷矿为代表，从成矿地质体、成矿构造系统与成矿结构面，以及成矿作用特征标志“三位一体”进行对比研究。以早寒武世含磷岩系为成矿地质体，以中宜村段碳酸盐岩、硅质岩及磷块岩含磷岩系为主要成矿构造岩性岩相界面，梳理沉积成矿作用特征标志，建立“三位一体”地质模型。总结形成了快速找矿技术方法：“沉积盆地建造(成磷盆地) + 层位 + 岩性界面(标志层) + 磷矿层 + 钻探”。
Abstract: The exploration and discovery of the Xundian Mozushao large-scale phosphorus deposit and the new breakthrough in the industry in recent years, the super-large phosphorus deposit in the Yangchang-Mangbu area of Zhenxiong County, Yunnan Province, have further verified the distribution law of the regional phosphorus belt extending to NE, and presented the space and direction for the regional search for concealed phosphorus deposits. In this paper, the theory and method of prospecting prediction in exploration area are used to study typical deposits. From north to south, three typical deposits of phosphate-accumulating basins, Xiaotan-Yangchang, Jiulong-Huize and Kunming-Huaning, are formed. The Yangchang phosphate deposit in Zhenxiong County, the Mozuishao phosphate deposit in Xundian County and the Kunyang phosphate deposit in Jinning County are taken as the representatives. The ore-forming geological body, ore-forming structural system and ore-forming structural plane, as well as the “three-in-one” of ore-forming characteristics are compared and studied. Taking the Early Cambrian phosphorus-bearing rock series as the metallogenic geological body, and the carbonate rock, siliceous rock and phosphorus-bearing rock series of Zhongyicun section as the main metallogenic structural lithology and lithofacies interface, the characteristics of sedimentary mineralization are sorted out, and the “three-in-one” geological model is established. A rapid prospecting technology method was summarized “sedimentary basin formation (phosphorus-forming basin) + horizon + lithologic interface (marker layer) + phosphate rock layer + drilling”.
