摘　　要：近期吉林省宝石产商品质量监督检验站通过对我省长白石收藏爱好者的手中的不同品种长白印章石样品的红外光谱分析测试发现,长白冻石以珍珠陶石为主要矿物成分,而冻石中成冻非常好的呈胶状冻状的长白石,以多水高岭石—埃洛石为主要矿物成分,而长白印石中的彩石以地开石为主要矿物成分,否定了过去认为长白石主要由叶腊石、明矾石等矿物为主的观点,和单纯认为长白石主要由地开石为主的观点,为长白石的主要矿物成分及分级评价提供了可靠的理论依据。Recently, through analyzing different kinds of Changbai Seal Stone samples from Changbai stone collectors in Jilin Province, Jilin gem commodities quality supervision station uncovered that, the main mineral component of Changbai lardite stone is pearlite; the main mineral component of the gelatinous Changbai stone in lardite stones is halloysite; and the main mineral component of color stone in Changbai seal stone is dickite. These discoveries negate the dominant view on Changbai stone, which claims that its main components are pyrophyllite, alunite and other minerals, and the view that Changbai stone is mainly composed of dickite. This study provides a reliable theoretical support for the mineral components and rating method for Changbai stone.
