摘要: 确认了辽宁医巫闾山地区富含细微粒镁铁质包体的中侏罗世埃达克岩体的存在，对其岩石学及地球化学特征进行了分析，并结合近些年的研究成果，将闾山地区构造演化过程厘定为4个阶段，对每一个阶段的构造背景进行了初步探讨.

Abstract: The authors confirm the existence of Middle Jurassic adakite which is rich in mafic microgranular enclaves (MMEs) in Yiwulyushan, Liaoning Province. With analysis of the petrological and geochemical characteristics of the rocks, the tectonic evolution process in the region is divided into four phases, of which the tectonic settings are studied based on recent research results.
