摘　　要：贵州开阳地区是我国富磷矿集中分布区。近年来,通过产学研协同创新、联合攻关,实现了磷矿理论创新,推动了该区磷矿找矿突破;厘清了开阳地区磷矿成矿受黔中古陆长期剥蚀夷平的平缓海岸型的无障壁海滩(缓坡浅滩)环境控制;建立了富磷矿"三阶段"动态磷矿成矿模式,阐明了"富"的成矿作用过程,即原始生物-化学、波浪波选(机械)暴露淋滤、磷质沉淀胶结成矿作用。建立新的磷矿区域成矿模式和地质找矿预测模型,开展找矿预测,通过工程验证,估算磷矿资源量(333+334?) 54892万吨,取得了富磷矿找矿新的重大突破。预测区内富磷矿还有8亿吨的找矿潜力。Kaiyang,Guizhou Province is the most concentrated distribution area of rich phosphate deposits in China.In recent years,through the collaborative innovation of industry,universities,and research institutes and joint research,the theoretical innovation of phosphate rock has been realized,and breakthroughs have been made in the prospecting of ore deposits in the area.The clear shoal environmental controlformed by the long-term erosion and flattening of the ancient land in the central area of Guizhou Province has been clarified in the Kaiyang area.it established the "three-phase" dynamic phosphorite mineralization model of phosphate-enriched ore,and clarified the "rich" metallogenic process,namely the original biological-chemical,wave-wave selective (mechanical)-exposed leaching and mineralization,Bio-chemistry.A new regional metallogenic model and geological prospecting prediction model is built up,it carried out prospecting predictions,and through project verification,the amount of phosphorite resources (333+334?) 5,489,200 tons is ensured,especially the newly added phosphorous ore,357 million tons,which has made China Rich Phosphate prospecting major breakthrough.There are also 800 million tons of prospecting potential in the prospected phosphate-enriched ore reserves.
