几年来地質工作者在党的正确領导下,所进行的磷矿地質勘查工作,获得了輝煌的成果,已在云南、貴州、四川、湖南、湖北等省,找到了一些經济价值很大的下古生代沉积类型的磷矿床,为西南各省磷肥生产,确定了可靠的原料基地。淮河流域是我国重要农業生产地区之一,在这一地区已經找到的磷矿床,計有宿松前震旦紀錦屏式变質岩类型磷矿床及鳳台、霍邱下塞武紀鳳台式沉积类型的磷矿床。这些矿床由于 Over the past few years, under the correct leadership of the party, geologic workers have achieved brilliant achievements in geological exploration of phosphate rock and have found some great economic value in Yunnan, Guizhou, Sichuan, Hunan and Hubei provinces The Lower Paleozoic sedimentary type of phosphate deposits, for the production of phosphate fertilizer in the southwestern provinces, has identified a reliable raw material base. The Huaihe River Basin is one of the important agricultural production areas in China. Phosphate deposits already found in this area include the pre-Sinian Jinping metamorphic rock type phosphate deposit and the Fengtai and Huoqiu sub-Jiwufeng stations Types of phosphate deposits.
