岩浆岩侵入下煤变质程度的控制因素分析

摘要

The Permo-Carboniferous coalfields in the Shandong Province are typical coalfields seriously impacted by magmatic intrusion in the country. This potential assessment is through collection of actual production and exploration data from coalmines, exploration areas, carried out analytic study of coal seam metamorphic features and relation between magmatic intrusions in the revealed magmatic intruded areas. General patterns of coal seam metamorphism and magmatic intrusion impacts have been summed up. Thus, theoretical basis of coal resources exploration and exploitation in the province has been provided.%山东省石炭一二叠纪煤田为全国较为典型的岩浆岩侵入影响较严重的区域之一,本次潜力评价工作通过收集各矿井、勘查区的实际生产和勘查资料,对已揭露的岩浆岩侵入区的煤层变质特点与岩浆岩侵入之间的关系进行分析研究,总结山东省煤层变质与岩浆岩侵入影响的一般规律,为今后山东省煤炭资源的勘查开发提供理论依据.
