摘　　要：中国非金属超大型矿床与板块构造和地壳演化的关系，表现在不同板块构造环境形成不同的超大型非金属矿床组合，相同板块构造环境而不同板块对象所形成的超大型非金属矿床又各有侧重。另外生物圈演化对石墨、磷矿和硅藻土，水圈（古海水）演化对菱镁矿等超大型非金属矿床的形成也有重要的制约作用。Super-large non-metal deposit assemblage formed in different plate tectonic environment reflected the relationship between Chinese super-large non-metal deposits and plate tectonic,the crustal evolution. Even if in identical plate tectonic environment, super-large non-mdtal deposits produced in different plates would be not alike. In addition,the formation of super-large non-metal deposits such as graphite deposit,phosphorite deposit and diatomite deposit was restricted greatly by the evolution of biosphere,magnesite deposit by the evolution of hydrosphere (paleoseawater).
