摘　　要：现代盐湖生物学的研究和蒸发岩中生物化石的研究都表明，生物在包括芒硝矿床在内的蒸发岩矿床形成中起着重要作用。传统地质学认为蒸发岩是纯化学沉积矿床的观点应予修正。蒸发岩生物成矿研究目前尚处于初级阶段，还需要引入新的研究方法，开展摸拟生物成矿实验，进行更深入的成矿机理方面的研究。Endongenic phosphate deposits are referred essentially to amagmatic type of phosphate deposit,taking an important percentage in the worlds phosphorus resources.Of three principal types of endogenic phosphours deposits over the world,the most valuable to development is those which lie along the margins of old platforms or mobile zones,being controlled by profound faults and associated with ultrobasic alkalic carbonaterocks.In Chinas North China and Talimu platforms,more than 40 alkalic rock bodies have been found,showing a good prospects for ore hunting but emphasis in metallogenetic prognosis should be put on profoundly understanding mineralizing rules,orientation of in question rock bodies and their geological properties.
