摘要
通过对莱芜煤田四个主要岩浆岩的来源、分布范围、岩性、岩相和产状以及同位素年龄等特征的分析研究，揭示了该区岩浆岩的发育规律，并指出了岩浆活动对煤炭资源评价和矿井生产的影响。
The development regularities of four dominate magmatic rock bodies in Laiwu coalfield are discovered in aspects of their origins,scope of distribution,lithologic and petrographic features,as well as attitudes and isotope ages.The influence of magmatic activities on coal resource evaluation and mining operation are suggested.
