苏皖北部与辽南上元古界地球化学特征对比与郯庐断裂带平移问题
COMPARISON ON THE GEOCHEMICAL CHARACTERS OF THE UPPER PROTEROZIC ERATHEM IN SOUTHERN LIAONING AND NORTHERN JIANGSU AND ANHUI AND THE TRANSLATION OF TANCHENGLUJIANG FAULT ZONE
【摘要】 郯城—庐江断裂带平移是近年讨论较多的一个问题。作者在研究了苏皖北部和辽南晚元古代地层地球化学特征之后,发现两地区地球化学特征存在着明显的差异,它们不属于同一沉积盆地。因此,从地球化学角度看,郯庐断裂带不存在巨大平移。从区域构造和地球动力学考虑,晚元古代时期,华北地块东部的地壳波浪状锒嵌构造格局对剥蚀区与沉积区的展布及演化起着明显的控制作用。苏皖北部与辽南上元古界之间的地球化学差异性,在宏观上是构造差异性的物质表现。
【Abstract】 The translation of Tancheng-Lujiang Fault Zone is argued in recent years,and on which many scholars call in questions in many ways.On the research of the geochemical characters in the later Pro- terozic stratum of southern Liaoning and northern Jiangsu and Anhui,the auther found that the geological characters of the area were quite different,and they were not the product of the same sedimental basin.So there is no great translation existing from geochemistry. On the regional tectonic and geody- namics,in the later Proterozic Era,the pattern of the crustal wavy mosaic struture in the east of the North China block played a controlling role in the distribution and evolution of the denudating and sedimental areas.The Geochemical difference between the upper Proterozic Erathem in southern Liaoning and northern Jiangsu and Anhui is the material expression of tectonic difference macroscopicly.
