| Abstract: | There are many gabbros in Nanjing-Wuhu area, but the isotopic ages of the gabbros were not dated exactly.It is not cleared that the relationship between coexisting iron-forming augite-diorite and gabbros.The authors used the method of whole-rock-mineral (apatite and biotite) Rb-Sr isochron and obtained the age of the gabbros from Jiangmiao in Naming is 125Ma, Isr=0.7050,εNd(t)=+1.4; Yanghutang in Ma’anshan is 125Ma, Isr=0.7054, εNd(t)=+1.3; and Gushan in Dangtu is 129Ma, Isr=0.7064 respectively. |
