摘要
本文以地质学、地貌学、岩石学为理论基础,通过野外调查并参照前人的研究成果,对孟良崮地区的岩石特征进行分析.结论显示,太古代侵入岩体主要是超基性、基性岩组成的万山庄岩套和以条带状英云闪长岩及片麻状英云花岗闪长岩为主的蒙山岩套.元古代早期侵入的是以条带状黑云二长花岗岩为主体的傲徕山岩套和牛岚辉绿岩.孟良崮地区的变质岩主要是泰山岩群残留体和区域变质、动力变质、接触交代变质侵入体.孟良崮包体带形成于2500-2450 Ma五台运动时期.
This paper was based on the theory of geology,geomorphology,petrology through field investigation with reference to previous research results to analyze the rock characteristics of Menglianggu region.Conclusion shows that archaean intrusive mass was mainly of Wanshanzhuang suite which consists of basic rock 、ltrabasic rock,and Mengshan suite.And Mengshan suite was composed of Banded tonalite and Gneissic granodiorite.In Menglianggu region,the early proterozoic intrusion＆#39;s was Aolaishan suite which the main body was banded biotite monzonitic granite and Niulan diabase.Menglianggu region＆#39;s metamorphic rock was mainly the residue of Tarzan suite,regional metamorphic rock,dynamic metamorphic rock and contact metasomatic intrusion.Menglianggu xenoliths zone formed in ＆quot;five uplift＆quot; movement in 2 500～2 450 Ma.
