SHRIMP U-Pb and CAMECA 1280 Oxygen Isotope Results From Ancient Detrital Zircons in the Caozhuang Quartzite, Eastern Hebei, North China Craton: Evidence for Crustal Reworking 3.8 Ga Ago
Simon A. WildeJohn W. ValleyNoriko T. KitaAaron J. CavosieDunyi Liu
The Caozhuang quartzite, located in Eastern Hebei Province in the eastern part of the North China Craton, has long been known to contain the oldest detrital zircon population in China....
The Jiaobei massif constitutes the southern segment of the Paleoproterozoic Jiao-Liao-Ji belt in the Eastern Block of the North China Craton, and contains high-pressure (HP) mafic and pelitic granulites. The...

Paleoproterozoic Crustally Derived Carbonate-Rich Magmatic Rocks From the Daqinshan Area, North China Craton: Geological, Petrographical, Geochronological and Geochemical (Hf, Nd, O and C) Evidence
Yusheng WanDunyi LiuZhongyuan XuChunyan DongZhejiu WangHongying ZhouZhensheng YangZhenghong LiuJiashan Wu
Most carbonate-rich magmatic rocks are mantle-derived, namely carbonatite(s), with a minority of them being contaminated by crustal rocks. It is debated whether there are also carbonate-rich magmatic rocks derived solely...
