摘要:

甘孜—理塘缝合带内变质石英砂岩普遍经历低级变质,野外工作中未发现化石标本,岩石组合特征和地层序列表明其沉积环境为滨浅海。选取川西理塘县城北的缝合带内变质石英砂岩作为研究对象,测定砂岩内单颗粒碎屑锆石U-Pb年龄分布范围为3 264~495 Ma,峰值主要集中在544~495 Ma,1 000~730 Ma,1 220~1 050 Ma,1 563~1 367 Ma,1 761~1 648 Ma,并且存在少量2 514 Ma(1颗)和3 264~3 220 Ma(2颗)的太古宙古老年龄锆石。对比相邻区域地层组合和碎屑锆石直方图特征,限定地层形成的时代为奥陶纪,初步判断其物质成分来源于扬子西缘和西藏地区,表明甘孜—理塘缝合带中存在构造成因的古生代外来岩块。

Abstract:

 The metamorphic quartz sandstones in the Ganzi-Litang suture zone experience low grade of metamorphism,no fossil samples were found during the field work.The sedimentary succession was deposited on the coastal and shallow sea environments.Ages of detrital zircons from the metamorphic quartz sandstones have a population ranging mainly from 3 264 to 495 Ma,yield five U-Pb age clusters of 544~495 Ma,1 000~730 Ma,1 220~1 050 Ma,1 563~1 367 Ma and 1 761~1 648 Ma,beside three old Archean zircon grains,therefore,the rocks have maximum depositional ages of 495 Ma.Compared with the detrital zircons histogram feature and stratigraphic assemblage characteristics from adjacent regions,the data suggests that the zircon grains have very complicated sources,but mainly from the western margin of the Yangtze Block.
