塔里木盆地中部辉绿岩脉LA-ICP-MS锆石U-Pb年龄及其地质意义
LA-ICP-MS zircon U-Pb age of dykes from central Tarim Basin and its geological significance
摘要
Abstract
Seismic data obtained from the central Tarim Basin show that lots of diabase dykes are developed in Cambrian,Ordovician and Permian strata.Diabase dykes that invaded into Silurian and Ordovician strata were collected near the fault zone (Zhong 1 well,Zhong 16 well core).Using LA-ICP-MS determination technology,the authors determined U-Pb age and trace elements in zircon.Zircon U-Pb age shows that the diabase dykes were formed in the Early Permian period of 273～296Ma.Measured 700～930Ma (Late Proterozoic) and 396～544Ma (Paleozoic) show the tectonic-magmatic activity when basin was formed.121.0±8.5Ma (Early Cretaceous) zircon indicates that the formation was related to hydrothermal activities in the same period.关键词
