| 摘 要： | 出露于扬子地块东南缘的幕阜山复式岩体侵位年龄约为145Ma.该复式岩体的花岗闪长岩及其暗色微粒包体都含有独特的岩浆绿帘石.这些绿帘石呈自形晶,普遍发育熔蚀结构,部分具褐帘石核.微粒包体及花岗闪长岩中绿帘石的Ps值((100Fe3+/(Fe3++Al))均集中在26～28,TiO2含量小于0.2%,为典型的岩浆成因.岩相...

| Abstract: | Exposed in the southeastern margin of Yangtze Block,Mufushan complex batholith has an emplacement age of 145 Ma(Zircon U-Pb).Granodiorite and its mafic microgranular enclaves from the batholith contain characteristic monocrystalline epidotes.Most of these epidotes are idiomorphic,featured frequently with melting corrosion structure and occasionally with allanite-rich cores.The Ps values((100Fe3+/(Fe3++Al))of both kinds of epidotes mainly fall between 26 and 28,while TiO2 contents of these epidotes are less ... |
