摘要
文章论述了黑龙江省煤类分布5个不同时代成煤期的变质规律和特点。煤变质以深成变质为主,中生代煤变质迭加有岩浆热变质,岩浆热变质具有明显的分带性,动力变质作用微弱。对黑龙江省煤类分布特征进行了详细分析。
This paper discusses the metamorphose rule and characteristics of coal type distribution in five different coal-forming period. The coal metamorphose is major in plutonic metamorphism, coal metamorphism in Mesozoic contains with magmatic thermal metamorphism The magmatic metamorphic has obvious zonation and dynamic metamorphism is weak. The distribution characteristics of Heilongjiang coal type are analyzed in detail.
