浅谈广东珍珠岩资源、膨化工艺条件和开发应用前景

ON THE RESOURCES,EXPANSING TECHNIQUE AND DEVELOPMENT OF PERLITE IN GUANGDONG

广东的珍珠岩矿床主要产于粤东中生代火山盆地中，与沸石岩、膨润土密切共生，有多种工业类型，储量巨大。其膨胀性能良好，技术经济指标较先进。目前，广东珍珠岩大都用作建筑材料。随着国民经济建设的发展，珍珠岩的应用领域必将不断扩大，深加工技术也将迅速进步。

The perlite deposits in Guangdong occur mainly in the Mesozoic volcanic basin of eastern Guangdong and coexist with zeolite and amargosite with various industrial types and huge sum of reserves.The expansibility of the perlite is superb,and the technique and economic index are also favourable.At present,the perlites are mostly used as building materials.With the development of the national economy,the applied field of perlite will be enlarged,and great progress will be made in deep processing technique.The prospects for the development and utilization of perlite in Guangdong is bright.
