| Geochronology of Neoproterozoic Mafic Intrusions in North Huaiyang Area |
| There are a few metamorphosed and deformed mafic intrusions in North Huaiyang area, the northernmost part of Dabie orogen. The U-Pb data presented in this paper show that they were formed in Neoprterozoic Era (784 ±18 Ma) , similar to the formation time of TTG gneisses in North Dabie terrain. Major elements in the intrusions are different from those in the mafic-ultramafic intrusions of North Dabie terrain. |
