Abstract:Mesozoic granitic magmatism is developed in the Zhangguangcaling area. However, accurate isotopic age data is lack for the granite in the area. Based on the 1:50 000 regional geological and mineral resources survey in Heilongjiang Province, the author carries out the zircon U-Pb isotopic dating for the granitic rocks in the area. The results show that the Triassic granite was formed in 224-229 Ma; while the Jurassic intrusive rock is dated as 202-193 Ma.
