Tectonics, Volume 43, Issue 3, March 2024.Abstract The relation of plate kinematics to the structural record of arc plutons and their host rocks is complex and still not fully understood. We address this issue through a combination of field mapping, structural analysis, anisotropy of magnetic susceptibility analysis, and fabric modeling in the Late Cretaceous Tuolumne Intrusive Complex, Sierra

Geophysical Research Letters, Volume 51, Issue 2, 28 January 2024.Abstract Silicic magmas are the most viscous of all magmas, however some granitic plutons display remarkably homogeneous compositions, which contradicts the hypothesis that mechanical mixing is the main homogenizing process in the magma chamber. Thus much remains controversial about the mechanisms responsible for the homogeneities of silicic plutons ...

Island Arc, Volume 33, Issue 1, January/December 2024.Abstract Zircon U–Pb dates for felsic and intermediate to mafic dikes intruding into the Ryoke granitoids and metamorphic rocks at selected outcrops in the Takamiyama area of the eastern Kii Peninsula, southwest Japan, were determined along with their geology and petrography to reveal the history of Cretaceous magmatism. At each outcrop, the felsic and

Geochemistry of Mafic Enclaves and Host Granitoids from the Chilliwack Batholith, Washington: Chemical Exchange Processes between Coexisting Mafic and Felsic Magmas and Implications for the Interpretation of Enclave Chemical Traits [PDF]
, 2004 Mafic enclaves from three plutons in the Chilliwack batholith have been compared with contemporaneous mafic stocks in order to determine (1) the processes by which mafic and felsic magmas hybridize in the plutonic environment and (2) whether analysis of ...

Geofluids, Volume 2024, Issue 1, 2024.The Bangxi–Chenxing suture zone is an essential area from which information about the closure history of the eastern Paleo‐Tethys Ocean can be obtained. The Darongshan granitoid, which is adjacent to this suture, lies among the widely distributed granitic rocks and few basic rocks in the southern Guangxi Province.

Model for the Origin and Significance of Microgranular Enclaves in Calc-alkaline Granitoids
, 1991 The origin and significance of microgranular enclaves as indicators of the occurrence of magma mixing and/or mingling episodes between basic magmas and anatectic acid magmas, either I- or S-type, are re-evaluated.

Journal of Mineralogical and Petrological Sciences, 2003 Sulfide, oxide, and amphibole in MME (mafic microgranular enclaves) in the young Kurobegawa Granitic Pluton (2 Ma) indicate that their textural and mineralogical features are characteristic of progressively oxidized magnetite-series granitoids. Hydrous mafic magma intruded into the chamber from the bottom and fragmented to form MME, subsequently ...
