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。
The paper discusses the metamorphic rules and characteristics of coal formation in five different ages in Heilongjiang Province. Metamorphism of the coal is mainly metamorphism. The Mesozoic coal metamorphism superimposes magmatic thermal metamorphism, and the magmatic thermal metamorphism has obvious zonation and weak dynamic metamorphism. The characteristics of coal distribution in Heilongjiang Province were analyzed in detail.
