摘　　要：卡哈洛磷矿磷矿石以磷质碎屑(砂屑、鲕粒、砾屑、团块、生物碎屑)结构为主,次为胶状泥晶结构;原生磷块岩矿石主要有纹层-条带状和块状两种构造类型,矿石中磷酸盐矿物为泥晶磷灰石(胶磷矿)。矿床形成于水体较浅、水动力条件强、以波浪作用为主的潮下浅滩环境。Kahaluo phosphorite are composed of phosphorus clast （sand, oolite, gravel, lump, biodetritus） and colloform micrite, the phosphate minerals in the lamina and banded primary phosphorite are composed of micrite apatite （collophane）. The deposits were formed in the wave effect shoal environment with shallower water body and strong water power.
