The Paleoproterozoic Yinyugou Group in the southern North China Craton is a littoral facies sedimentary sequence which is mainly composed of feldspar quartzites and mica schists with minor carbonate rocks. U-Pb isotopic dating of detrital zircons bracket the depositional age of the Yinyugou Group at ∼2.43–2.30Ga. Chemical Index of Alteration (CIA) values of most feldspar quartzite and schist samples...
The evolution of the North China Craton (NCC) is well known for a marked 2.55–2.50Ga tectonothermal event. However, supracrustal and intrusive rocks of 2.75–2.70Ga are in fact widely distributed in the western Shandong Province, the most important area of Archaean basement in the eastern part of the NCC. This paper reports SHRIMP U–Pb dating and LA-ICPMS Hf isotopic composition of zircons from 2.75–2...
