英文摘要 | The Neoproterozoic Hualong Complex dominates the South Qilian terrane. It contains mafic to felsic magmatic rocks, cherts and turbiditic sediments, some of which have been metamorphosed to amphibolite grade and is traditionally regarded as a pre-Cambrian micro-continental block rifted from the South China plate. New U-Pb geochronology of morphologically complex zircons sheds light on the history of the complex. Garnet-bearing amphibolite and quartzite have detrital zircon U-Pb main peak ages of 1.47-1.78 Ga with youngest U-Pb ages of 967 Ma and 964 Ma. They are intruded by Neoproterozoic orthogneisses that crystallized between ca. 850 and 940 Ma. Psammitic paragneisses are dominated by 940-780 Ma detrital zircon populations with a youngest U-Pb weighted mean age of 721 +/- 3 Ma and a main peak at 906 Ma. |
