| 英文摘要 | The Tabeaksan basin is situated between the Kyonggi and Yongnam blocks, central-eastern Korea Two samples were respectively sampled from the Lower Cambrian and Middle-Upper Carboniferous ( Lower Permian?) sandstone layers of the basin, which detrital zircon U-Ob ages were measured by the LA-ICP-MS method. The sample 03TB01, 27 age data, records three reliable tectonic-thermal events in 1820 similar to 1945Ma, 2172 similar to 2195Ma and 2473 similar to 2593Ma, with relative probability peak ages of 1897Ma, 2177Ma and 2528Ma. The sample 03TB09, 47 age data, records five reliable tectonic-thermal events in 288 similar to 340Ma, 461 similar to 474Ma, 1780 similar to 1892Ma, 1941 similar to 1959Ma and 2012 similar to 2050Ma, in which most ages fall into two events with relative probability peak ages of 305Ma, 1867Ma. It was found that one similar tectonic-thermal event about 1850Ma all occurred in the Tabeaksan basin and the Kyonggi and Yongnam blocks, with lack of Neoprotolozoic zircon ages distinct to the South China block. Based on the published depositional paleocurrent an(] paleogeographic framework of Lower Cambrian and Middle-Upper Carboniferous ( Lower Permian?) for the Tabeaksan basin and its adjacent area, this research presents that close detrital provenance relationship existed between the Tabeaksan basin and Yongnam block at least during those periods of time, which tectonic attribute can be compared with the North China craton. On the other hand, though the Middle-Upper Carboniferous ( Lower Permian?) sample records zircon U-Pb peak ages of 305Ma and 468Ma, probably related to tectonic-thermal events occurred in south margin of the united North China-Korea block, no detrital provenances supplied the Tabeaksan basin at least before Late Carboniferous ( Early Permian?) due to few Neoprotolozoic tectonic-thermal events recorded in dtrital zircons of the two samples mentioned above. |
