摘　　要：麻田磷矿是多因富化的复成矿床。本文对成矿环境及沉积分异,火山喷发,热液交代,次生淋滤等室化因素做了分析论证,并提出多因素(沉积,热液,淋滤),多阶段(原生沉积成岩后生次生淋滤)成矿模式。The matian phosphate deposit is polygenetic one of many factors of enrichment. This paper analyses and discusses enriching factors of the metallogenetic conditions, differentiation of deposit eruption of volcanos, pyrometasoma- ties, secondary leaching and so on. Besides, the paper preaents a metallogenetic type of many factors (depositing, hydrothermal, leaching)and many stages(connate deposit, epigenetic deposit of deuterogene, leaching). This will be definitely helpful to seek phosphate ore in the rock series containing phosphate and to seek rick ores in ore—poor areas.
