英文摘要High-Mg diorite - hornblende-granite occurs at Guyang, Inner Mongolia. Geochemically, the high-Mg diorite is similar to late Archean sanukite that was formed in mantle wedge above subduction zones. Sanukite, which finds common in Archean terrains worldwide, is characterized by high MgO content and high Mg-# associated with enrichments of Cr and Ni. This paper reports SHRIMP U-Pb ages of a high-Mg diorite (2556 +/- 14 Ma) and a hornblende-granite (2520 +/- 9 Ma) in the Guyang area. Accordingly, the subduction of the North China plate possibly initiated during the late times of the late Achaean. The Archean Sanukites outside of China have been well documented in the range of 3.0 similar to 2.5 Ga with the youngest (2.51 similar to 2.55 Ga) occurring in the Dharwar Craton of India. It is suggested that the North China and synchronous India could be the latest areas developing plate tectonics on Earth.
