摘要:Abstract(#br)A rare garnet-bearing mafic granulite boulder has recently been identified from the Larsemann Hills, East Antarctica, with the development of two-stage decompression textures. Detailed petrographic study and P-T estimates suggest three distinct metamorphic stage...

摘要:Abstract(#br)It has been established that almost all known mantle plumes since the Mesozoic formed above the two lower mantle large low shear velocity provinces (LLSVPs). The Hainan plume is one of the rare exceptions in that instead of rising above the LLSVPs, it is located...

摘要:Abstract(#br)Antarctica contains continental fragments of Australian, Indian and African affinities, and is one of the key elements in the reconstruction of Nuna, Rodinia and Gondwana. The Bunger Hills region in East Antarctica is widely interpreted as a remnant of the Mesop...

摘要:Abstract(#br)A palaeomagnetic study was carried out on the newly identified 1888 ± 9 Ma Boonadgin dyke swarm of the Yilgarn Craton in Western Australia. The Bonnadgin dykes yield a mean direction of magnetisation of D = 143°, I = 13°, k = 37 and α 95 = 8°, based on samp...

摘要:Abstract(#br)The flat-slab subduction model has been proposed to explain the complex Mesozoic–Cenozoic geotectonic record of SE China as part of the Western Pacific margin. Here we investigate the post-250 Ma thermal history of the Shaoguan-Longnan region to evaluate the tim...

摘要:Abstract(#br)Hafnium isotopes of zircon represent a well-dated proxy for the evolution of magmatic systems through Earth history. Time series analysis on the hafnium isotopes of zircon reveals a hierarchy of statistically significant periodic signals spanning multiple orders...

摘要:Abstract(#br)Chemical composition of sedimentary rocks bears important clues on source rock characteristics and sedimentary processes, providing a critical record of the evolving continental crust. Whole-rock major and trace elements, and detrital zircon U-Pb-Hf isotopic dat...

摘要:Abstract(#br)Hainan Island in southwestern south China has 1.43 Ga crystalline rocks as part of the Proterozoic basement rocks for the Cathaysia Block. Understanding Proterozoic tectonics of the island is thus essential for constraining the paleogeographic positions of the C...

摘要:Abstract(#br)We report here new zircon U-Pb age and Hf-isotope as well as geochemical analyses of the recently discovered Archean-Paleoproterozoic Zhongxiang Complex in the northern-central Yangtze Craton, South China, and interpret the early crustal evolution of the Yangtze...

摘要:Abstract(#br)The Archean Yilgarn Craton in Western Australia hosts at least five generations of mafic dykes ranging from Archean to Neoproterozoic in age, including the craton-wide ca. 2408 Ma Widgiemooltha and the 1210 Ma Marnda Moorn Large Igneous Provinces (LIP), the 1888...
