Abstract
This study focuses on the zircon U–Pb geochronology and geochemistry of intermediate–basic dikes from the Buqingshan–A’nyemaqen tectonic melange belt (BTMB) along the southern margin of the East Kunlun orogenic belt (EKOB). Zircons from a diorite dike show oscillatory zoning and relatively high Th/U ratios (0.47–2.43), indicating that they are of magmatic origin. Using LA–ICP–MS, zircons of the diorite dike yield a U–Pb age of 205 ± 1 Ma...
