本文简述了庐山隆-滑构造的基本特征。在中元古代双桥山群底部的顺层韧变带中,把前人的断层构造砾或沉积成因的巨厚层状变质复成分砾岩,自上而下分离出三层砾:上部砾、中部砾、下部砾。其中上部砾为断层构造砾;中部砾不是砾,而是构造分泌物;下部砾为沉积底砾。在此基础上,同时参考研究区早元古代星子群与中元古代双桥山群构造、岩浆活动、变质作用等方面的差异,建立了“庐山运动”,其活动时间为2200~1800Ma,这可以与华北及华南其它地区同时期的构造运动相对比,但庐山运动的强度相对较弱,表现为以垂直隆升为特色的造陆运动,它曾使研究区早元古代晚期至少遭受过长达200Ma(1800~1600Ma)的风化、剥蚀作用。
This article briefly describes the basic features of the Lushan Longlian-slip tectonics. In the stratigraphic ductile belt at the bottom of the Mesoproterozoic Shuangqiaoshan Group, three layers of gravel are separated from top to bottom by the giant thick metamorphic complex conglomerate of previous fault structure gravels or sedimentary origin: the upper gravel , Middle gravel, lower gravel. The upper gravel is the faulted gravel. The middle gravel is not gravel but the exudates. The lower gravel is the sedimentary gravel. On the basis of this, referring to the difference between the Early Proterozoic asteroid group and the Mesoproterozoic Shuangqiaoshan Group in the study area, the “Lushan Movement” was established with an active time of 2200 ~ 1800Ma It can be compared with contemporaneous tectonic movements in North China and other parts of South China. However, the Lushan movement is relatively weak in intensity and shows as a land-built movement characterized by vertical uplift, which has at least suffered from being overlong in the early Early Proterozoic Up to 200Ma (1800 ~ 1600Ma) weathering and denudation.
