补充资料:磷块岩
   分子式  3Ca3(PO42CaF2
   性质  磷块岩是一种以碳氟磷灰石为主动脉矿物组分的沉积磷矿,脉石矿物有石英、玉髓、方解石、白云石、水云母、高岭石 、海绿石及有机质等。颜色呈黄褐、绿褐、浅灰、深灰或黑色。硬 度2~4,密度2.8~3.0g/cm3。碳氟(磷灰石有两种形态:一种是具有微细晶粒或隐晶质呈草莓状、葡萄状、皮壳状的集合体,另一种 为非晶质或显微隐晶质呈胶体外貌的集合体,俗称“胶磷矿”,后 者是磷块,后者是磷块岩中最主要的一种形态。碳氟磷灰石用肉眼 很难辨认,若在磷块岩上滴上含钼酸铵的硝酸溶液,则出现姜黄色 的磷钼酸铵沉淀。海相沉积的磷块岩往往矿床规模巨大,具有很大 的工业开采价值。
    用途  用于制造黄磷、 赤磷、 磷酸、 磷肥、 磷酸盐。
