摘　　要：　东北地区球粘土主要产于吉林省舒兰县、永吉县和黑龙江省牡丹江等地,属老第三纪,未固结成岩,主要由无序高岭石组成,无重结晶及有序化现象。常含少量有机质或与褐煤矿层等伴生。其可塑性、粘结性及干燥强度较好。球粘土的成矿主要受温湿气候、物质来源、搬运方式、沉积环境、构造及特定的时代、有机质的作用等条件控制。已知储量近2亿吨。In the Northeast China ball clay occurs in Shulan county, Yongji coranty, Jilin province, and Mudanjiang, Helongjiang province. It is the unsolidified sediment consisting of disordered kaolinite and small amount organic matter and lignite materials. No crystallization could be seen. And it is characterized by high plasticity, sitickness. The tolal reserves is about 2×10~6 ton.
