  • It is a puzzle to determine metallogenetic ages in the world. This article uses zircon fission track (FT) dating to probe the mineralizing epochs of Wulonggou (五龙沟) gold ore deposits in eastern Kunlun (昆仑) Mountains. Total of six zircon FT ages have been obtained and can be divided into groups of 235–216 and 197–181 Ma, as well as 162 and 124 Ma, revealing multiple epochs of metallogenetic processes took place in Wulonggou area, mainly first two age groups. The mineralizing ages become lower from northeast Yanjingou (岩金沟) to southwest Hongqigou (红旗沟). The second epoch of 197–181 Ma is first achieved by this work. It is shown that the FT ages consist with other isotopic data and reflect different regional thermotectonic events.
