| Abstract: | Zircon LA-ICP-MS U-Pb and Hf isotopic studies of the Neoarchean basement gneiss of the Miyun Group and overlying Meso-Neoproterozoic sandstones of the Changzhougou Formation of the Changcheng System and Changlongshan Formation of the Qingbaikou System from the Yan-Liao aulacogen in the Changping area,Beijing,are carried out in order to investigate the sedimentary and crustal evolution of the North China Craton (NCC).Zircon U-Pb dating on a pyroxene-bearing hornblende-plagioclase gneiss yields a protolith ag... |
