山东蒙山侵入岩分布与岩性特征
Distribution and Property Characteristics of Intrusive Rocks in Mengshan Mountain in Shandong Province
摘要
Abstract
On the basis of field geological survey, combining with petrology and chronology results of predecessors, according to the tectonism and igneous activity, distribution and property characteristics of intrusive rocks of Mengshan Mountain have been discussed.Mengshan Mountain area has complex geological structures.Magmatic activity has the characteristics of multi-stages and multi-cycles, and intrusive rocks develope well.The main body of Mengshan Mountain is composed of gneissic tonalite, gneissic granodiorite, monzonitic granite which formed by three periods of large scale magma intrusion activities in 2700~2500Ma.During 2750~2600Ma, super magnesia-mafic intrusive rock of Wanshanzhuang sequence and TTG (Trondhjemite, Tonalite, Granodiorite) rock series of Taishan sequence have been emplaced.About 2600~2500 Ma, Mengshan Mountain had been invaded by Xidianzi serpentine in Huangqian sequence, grain of trondhjemite, gneissic coarse grain biotite granodiorite, fine grain porphyritic biotite granodiorite in Yishan sequence, and banded biotite monzonitic granite and medium-grained dolomite quartz diorite in Aolaishan and Hongmen sequence successively.In the Mesoproterozoic period, about 1621Ma, Niulan diabase vein intruded in vein type.In the Palaeozoic period, about 465Ma, Changmazhuang kimberlite invaded.Large scale magma intrusion activities and tectonic action made ancient continent nucleus change greatly and forge repeatedly, formed a solid rigid continental crust,geological relics and landscape.关键词
