英文摘要	本文从内蒙赤峰至辽西凌源南北近200km的地质走廊中,选择早中生代(237～206 Ma)形成不同深度、不同产状的8种火成岩作为研究对象,探讨早中生代华北克拉通北缘的地质演化.这8种岩石包括:火山岩、岩墙群和闪长岩、碱性花岗岩、碱性杂岩、镁铁质麻粒岩、堆晶岩及其捕获的地幔岩包体.研究表明,在底侵作用的背景下,华北早中生代发生了强烈的壳幔相互作用和岩石圈地幔富集过程,伴随早中生代大陆地壳的增生和深部结构的调整,地表相应出现快速的差异抬升和剥蚀.; This paper presents a suit of igneous rocks in the SN-trending geological section with a length of about 200km from Chifeng (Inner Mongolia) to Lingyuan (western Liaoning Province), to explore the Early Mesozoic geological evolution of the northern margin of North China Craton. The Early Mesozoic (237 similar to 206Ma) igneous rocks occur as dyke swarm, diorite, alkali granite, alkali complex, mafic granulite, cumulate and its mantle enclaves that were derived from distinct depths. It is concluded that the lithospheric mantle beneath North China initially strongly interacted with and enriched by crustal materials and that magma underplating induced rapid differential uplift and denudation of continental crust, associated with accretion of the Mesozoic crust and adjustment of the lithospheric structure.; 国土资源部科技专项课题; 国家自然科学基金; 国家杰出青年基金; 中国科学院矿产资源研究重点实验室项目; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 7; 12; 3525-3534; 27
