摘　　要：通过对贵州某磷块岩的矿物组成成分及含量以及风化水解反应进行分析,说明风化反应与磷块岩的化学组成及微观结构有着密切的联系。磷块岩中碳酸盐的含量及其在磷块岩晶体中的赋存状态对磷块岩的酸解反应活性有着较大的影响。根据磷块岩酸解反应活性与磷块岩晶体微观结构的关系,最后得出易风化的磷块岩具有较好的酸解反应活性。On the basis of the mineral composition and content and analyzing weathering reaction of phosphate ore of Guizhou, it was concluded that weathering reaction had closer relationship with chemical composition and micro-construction of phosphate ore.The content of carbonate and its presence status in phosphate ore had large effect on acid decomposition activity of phosphate ore.According to the relations between acid decomposition activity of phosphate ore and micro-construction of phosphate ore crystal, it was pointed out that the phosphate ore easily weathered had good acid decomposition activity.
