| 摘 要： | 通过对抚顺煤田西露天矿的大比便尺填图以及横向追索,发现大量的接触热变质“烧变煤”的存在,观察到接触热变质带与辉绿岩呈明显的热接触关系。在此基础上,结合岩浆岩研究指出抚顺煤田煤变质为一种具有浅成、高温,作用时间较短的岩浆热变质作用的产物。

| Abstract: | The discovery of a great quantity of "burnt coal" with contact thermal metamorphism is made possible by large-scale mapping and lateral tracing in the western opencast of Fushun coalfield and a distinct thermal contact relation between the contact thermal metamorphic zones in coal seems and diabases is observed. Along with study of magmatic rocks, the au-thors propose that coal metamorphism in coalfield resulted from shallow magmatic thermal metamorphism with high temperature in a short time. |
