英文摘要 | 对科尔沁右翼中旗地区晚古生代地层进行碎屑锆石U-Pb定年研究。样品130909-01为凝灰质砂岩,130910-15为岩屑石英砂岩。碎屑锆石年龄可分为4组,由新到老依次为:252~278Ma、286~359Ma、381~462Ma和500Ma之前。碎屑锆石的最小年龄(256.5±1.7Ma)限定了地层沉积下限为晚二叠世。样品中出现大量残留锆石,记录了前寒武纪基底、早古生代岛弧岩浆岩和石炭纪—二叠纪岩浆活动事件。; The detrital zircon U-Pb geochronology of the Late Paleozoic strata in Horqin Right Wing Middle Banner was studied in this paper. Sample 130909-01 and 130910-15 were tuffaceous sandstone and lithic quartz sandstone samples, respectively. The detri?tal zircon ages can be divided into four groups: 252~278Ma, 286~359Ma, 381~462Ma and older than 500Ma. The youngest zircon age (256.5 ± 1.7Ma) constrains the maximum sedimentary age of the Late Permian. A large number of relict zircons were existent in the samples, which kept a record of Precambrian basement, early Paleozoic arc magmatic rocks and magmatic activity event during Permian-Carboniferous period.; 国家重点基础研究发展计划; 中国地质调查局项目; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 8; 1482-1492; 34 |
