摘要
本文利用大量的勘探资料,对东梁勘探区的煤变质特征及变质因素进行了研究,推断在含煤岩系下部2000～2500m处,可能存在一个侵入到下伏榆树沟组地层中的第三系中小型辉绿岩盖:东梁勘探区煤变质作用以远成岩浆变质占主导地位.
Based on the exploration data, the characteristics and factors of the coal metamorphism of Dong Liang exploration area has been studied. It is deduced that the metamorphism of the coal was caused by the heat of the erupting magma located at 2000-2500m below the coal measures. Therefore, the coal meta-morphism in DongLiang exploration area belogs to the telemagmatic metamorphism.
