The Vestfold Hills sector on the coastal fringe of the Princess Elizabeth Land forms part of an Archean to Paleoproterozoic aged cratonic nucleus of the East Antarctic Shield. A charnockite-granite association from the Mossel Gneiss Group in the northern region of the Vestfold Hills is investigated in this work to characterise the metamorphic-magmatic evolution of the area. Conventional thermometry and phase equilibria modelling indicate that the charnockite formed as a result of ultra-high temperature metamorphism at low-intermediate pressure (∼4 kbar). Phase equilibria modelling, reveals that the melt-integrated charnockite composition is a restitic product of a protolith of quartz diorite composition which underwent isobaric heating (peak temperature up to 960 °C) at 4 kbar pressure followed by anatexis. The anatexis of the quartz diorite protolith also resulted in the formation of the associated granitic melt. U–Th-Pb_Total ages obtained from monazites of the granite integrated with CHIME ages extracted using the isochron method indicate an emplacement age of ∼2200 Ma and two younger events are recorded at ∼2000 Ma and ∼1700 Ma. The younger ages are ascribed to the resetting during the emplacement of younger basalt dykes that cross cut the charnockite-granite sequence. Vestfold Hills’ geological correlations with Indian and Australian cratons are discussed considering this new data.

伊丽莎白公主地沿海边缘的西福尔德山部分是东南极地盾太古宙至古元古代克拉通核的一部分。这项工作对来自西福尔德山北部地区莫塞尔片麻岩群的辉绿岩-花岗岩组合进行了研究，以表征该地区的变质岩浆演化。传统的测温和相平衡模型表明，角铁矿是中低压力（~4 kbar）下超高温变质作用的结果。相平衡模型表明，熔融结合的斜长岩组合物是石英闪长岩组合物原岩的残留产物，该原岩在 4 kbar 压力下经历等压加热（峰值温度高达 960 °C），然后进行深熔作用。石英闪长岩原岩的深熔作用也导致了相关花岗岩熔体的形成。从花岗岩独居石中获得的U-Th-Pb_总年龄与使用等时线方法提取的 CHIME 年龄相结合表明侵位年龄为 ∼2200 Ma，并且记录了两个较年轻的事件，分别为 ∼2000 Ma 和 ∼1700 Ma。较年轻的年龄被归因于较年轻的玄武岩岩脉就位期间的重置，这些玄武岩岩脉横切了辉绿岩-花岗岩序列。考虑到这些新数据，讨论了西福尔山与印度和澳大利亚克拉通的地质相关性。
