摘　　要：吉林长白、抚松、临江的硅藻岩主要分布于第三纪马鞍山村组地层中．其岩石学、岩石地球化学和形成环境，与该区大面积分布的长白期（第三纪中新世）。Diatomite has been found in the diatomite-bearing Tertiary Ma'anshancun Formation in Changbai,Fusong and Linjiang areas in Jilin Province.Research results indicates that the petrology,lithochemistry and the producingenvironment of the diatomite are mainly related to the widely distributing baalts,ofwhich belongs to Changbai period(Miocene) and Junjanshan period(Pliocene).
