The Keyinbulake copper-zinc deposit is located at Chonghuer volcanic-sedimentary basin in Southern Altay.Granite pluton was exposed widely in this deposit,where the ore body occurred in the exocontact zones between granite and Upper Silurian-Lower Devonian Kangbutiebao Formation.In the underground mining process,there are geological phenomena of the diorite vein interspersed with copper and zinc ore bodies and granite.Zircon LA-MC-ICP-MS U-Pb dating of diorite has yielded a weighted average age of 262.0±2.1 Ma(MSDW=4.6),showing that the magmatic activitytook place in Middle-Late Permian.Combine with geological characteristic and the age of monzonitic granite,it’s confined taht the Keyinbulake copper-zinc deposit was formed in the Early-Middle Permian,with an age of appreciably 278~262 Ma.
