摘要
震旦系灯影组沉积磷块岩矿床,在国内少见,作为一个新的成矿期,无论在地壳活动,海水进退程序、生物演化,岩矿物质分异及地球化学环境方面,均具有独特之处。本区矿床属海水辐射上升环境下形成的磷块岩矿床,成因类型属地台边缘(或地槽前缘坳陷)型浅海海湾生物化学沉积的层状磷块岩矿床,并兼具碎屑堆积磷块岩特征。
Sedimentary phosphorite deposit of Dengying formation during Sinian Period as a new mineralization period, is unique in the crust activities, transgression and regression procedures, biological evolution and geochemical environ- ment. The area is a marine phosphorite deposit formed under increased ambient radiation.
