| 摘 要： | 贵州磷矿全国驰名,黔中瓮安磷矿是我同近几年来,发现并探明储量的大型沉积磷块岩矿床之一.本文从瓮安沉积磷块岩矿床地质特征入手,深入研究其形成机制和生成环境,提出瓮安磷矿形成于气候炎热干燥,海水近于封闭的滨岸环境。磷质来源以深海洋流上升带入为主,兼有原地生物堆积。聚磷方式既有化学絮凝作用,又有机械扰动和生物屑粘结作用。

| Abstract: | Phophorite deposits in Guizhou Province is well-known throughout China.The phosphoritemine in Weng'an Coun-ty,locared in the middle of Guizhou Province,is one of the largest sedimentary prosphoite mines.It was discovered and itsreserves have been prospected in recent year.Based on the geological features of the deposit,this paper studies the me-chani(?) origin and genetic environment.It puts forward the idea that the phosphorite is generated in the seashore which wasalmost completely enclosed by the water body and the arid and hot climate.The origin of phosphate was dominantly car-ried up (?)y the uplift current of deep sea water,and some was trom situ (?)ionts depos(?).The patterns of phosphate accumu-lation can (?) chemical Locculation,mechanical distur(?)ce.and cohesive atcion (?) oid(?)tritus. |
