摘　　要：广东硅藻土矿产资源丰富,主要分布于雷琼地区的雷州、徐闻等地,代表性矿床有雷州九斗洋大型矿床和徐闻九亩、雷州卜昌小型矿床。矿床成因类型为火山湖沼相沉积型,矿床形成受沉积盆地、物质来源及古地理环境条件控制。浅水湖盆构成成矿的良好场所,玄武岩类为生物提供了丰富的可溶性SiO2,高温多雨的气候条件有利于硅藻的大量繁殖生长。雷州半岛众多的古火山口湖盆和积水洼地是广东境内硅藻土的找矿远景区。Guangdong province is rich in diatomite mineral resources,mainly distributed in Leizhou,Xuwen and other places in Leiqiong area.Representative deposits include the Leizhou Jiudouyang large deposit and Xuwen Jiumu and Leizhou Buchang small deposits.The genetic types of the deposit is volcano-lacustrine sedimentary,the formation of the deposit is controlled by sedimentary basins,material sources and paleogeographical environmental conditions.The shallow lake basin constitutes a good place for mineralization.Basalts provide rich soluble SiO2 for living things.High temperature and rainy climate conditions are conducive to the proliferation and growth of diatoms.The numerous ancient crater lake basins and stagnant depressions in Leizhou Peninsula are the prospecting areas for diatomite in Guangdong,especially in Xuwen and Leizhou.
