Middle Precambrian 双语例句
The dating results of captured zircons show that the Middle-Late Jurassic (155-169 Ma), Indosinian (218-236 Ma), Hercynian (254 Ma, 294 Ma), Caledonian (413 Ma), and Precambrian (1823 Ma and 2542 Ma) magmatic events had taken place in the basin basement, which is consistent with the zircon U-Pb dating results from the basin basement rocks.
