| 摘 要： | 胶磷矿的矿物组成,主要是微碳—低碳磷灰石,及细晶磷灰石。而胶磷矿细微颗粒,经电镜观察鉴定,主要由磷酸盐化有机碎屑及藻席碎屑组成,早寒武世磷块岩的形成是生物学、沉积学、古地理—古构造等综合因素沉积作用的产物。

| Abstract: | The main mineralogical components of collophane are the apatite with trace amount C or low C and the francolite.The fine grained collophane is mainly composed of phosphatized organic clast and algal mat clast.The Early Cambrian phosphorite is formed by the comprehensive factors of biology,sedimentology,palaeogeography-palaeotectonics and phosphate shelf of Yangzi area. |
