| 摘 要： | 抚顺煤田的煤变质表现为一种具有浅成、高温、作用时间较短的岩浆热变质作用的特征。在西露天矿坑内和龙凤矿井下见有十分发育的接触热变质带,接触热变质煤未形成良好的天然焦,而是形成“炭渣状煤”或“烧变煤”。煤变质带明显,在平面上和垂向上都有所反映。煤变质带的分布与后期侵入的辉绿岩的分布关系密切。

| Abstract: | Coal metamorphism in Fushun coal field show the result of magmatic metamorphism with hypalyssal,high temperature and short time.Contact metamorphism is developed very much in the east of west open pit and under Longfeng mine.Contact metamorphic coal didn't form nature coke,but cindered coal.The zone of coal metamorphism is evident and related to the distribution of diabase which intrusion after main coal formation. |
