The metapelites contain coarse-grained granoblastic kyanite grains that are surrounded by sillimanite (Sil-II) with moat-like andalusite (And-II). The garnet grains in the garnet-bearing kyanite metapelites contain inclusions of andalusite (And-I) in their cores and sillimanite (Sil-I) in their mantles. Detailed textural characterization of the aluminosilicate phases indicates five distinct generations in the sequence andalusite (And-I), sillimanite (Sil-I), kyanite (Ky), sillimanite (Sil-II), and andalusite (And-II). Thermobarometric calculations and thermodynamic modeling suggest a hairpin-shaped P–T evolution with prograde conditions starting from ~530°C at 3.5 kbar, reaching a peak of 600°C at 6 kbar, and then a retrogression to ~550°C at 4 kbar. U–Pb zircon and U–Th–Pb monazite ages indicate that the multistage aluminosilicate formation has occurred during c. 260–245 Ma. The detrital zircon age distribution is essentially similar to those in the accretionary sedimentary rocks from the entire Altai Range (a sharp peak at 550–490 Ma and a broad peak at 900–700 Ma), but is characterized by more abundant Proterozoic zircon grains and an older maximum deposition age (Early Ordovician) compared with Devonian pelitic gneisses in the Mongolian Altai. These petrological and geochronological results indicate the following development of the orogen: (1) Subduction of an oceanic plate beneath a microcontinental block as early as 550 Ma, evidenced by the youngest peak of detrital zircon ages. (2) Development of the accretionary wedge and volcanic front due to maturation of the arc until c. 360 Ma. The development of the volcanic front due to the magmatism has provided abundant Paleozoic detritus to the accretionary wedge and has stemmed supply of Proterozoic detritus from the inland at the same time. (3) Burial of the youngest accretionary wedge at c. 360–350 Ma, which is not observed in the current samples. Ridge subduction has also been suggested to have occurred in this period. (4) Arc magmatism in the upper (older) part of the accretionary wedge during the late Permian that resulted in prograde high-T and low-P metamorphism (formation of And-I). (5) Burial of the heated accretionary wedge to a depth of ~20 km due to subsequent collision (formation of Sil-I and Ky) at c. 260 Ma. (6) Rapid exhumation of the buried accretionary wedge to a shallow depth by thrusting (formation of Sil-II and And-II) at c. 245 Ma. In summary, the metapelites in the Altai Range clearly preserve the evolution of both the accretion and collision events as well as their transformation processes, which are likely to be a good natural example of the Wilson cycle for a period of ~300 Myr.. |

The detrital zircon signature of the Triassic metasedimentary rocks corresponds to the Neoproterozoic sequence in the Indochina Block and that of the Silurian rocks corresponds to the Paleo- to Mesoproterozoic sequence in the southwestern margin of the Yangtze Block. From Triassic metaigneous rocks, we obtained three meaningful inherited ages; ~1450 Ma, 500 Ma, and 450 Ma. The Triassic metasedimentary rocks occur in close association with the Triassic felsic gneiss and mafic granulite (former eclogite) with magmatic inherited zircon ~1450 Ma and intermediate gneiss with ~500 Ma protolith age. The Hf isotopes suggest the ~1450 Ma age as the earlier or primary stage of the formation of the Indochina Block and the ~500 Ma age as the timing of its reworking, before the block subducted beneath the South China Block to form Triassic eclogite relicts. The Ordovician magmatic ages (~450 Ma) from metaigneous rocks in the Kontum Massif, combined with their volcanic arc whole-rock chemistry, Ordovician–Silurian low-pressure/high-temperature isobaric heating metamorphism, and the detrital zircon signature strongly suggest an Ordovician–Silurian continental arc in the present southwestern margin of the South China Block prior to the Triassic continental collision.. |

Nakano, N., Osanai, Y., Nguyen V. Nam, Tran V. Tri, Bauxite to eclogite: Evidence for late Permian supracontinental subduction at the Red River shear zone, northern Vietnam, Lithos, 302-303, 37-49, 2018.03, We have investigated the geological processes recorded in aluminous granulites from the Red River shear zone in northern Vietnam using mineral and whole-rock chemistries, fluid inclusions, metamorphic pressure–temperature paths, and geochronology. The granulites are extremely rich in Al2O3 (36.3–50.9 wt%), TiO2, and total Fe2O3, and poor in SiO2 (7.9–24.1 wt%), MgO, CaO, Na2O, and K2O. The granulites are enriched in high-field-strength elements and rare earth elements, and severely depleted in large-ion lithophile elements. These features strongly suggest the protolith was lateritic bauxite. Moreover, the other elemental concentrations and the Zr/Ti ratios point to basaltic rock as the precursor of the bauxite. Some of the aluminous granulites contain high-pressure mineral inclusions of kyanite, staurolite, siderite, and rutile, none of which are observed in the matrix. Abundant primary carbonic fluid inclusions are observed in garnet, corundum, and staurolite, but are rare in quartz and zircon. The average densities of fluid inclusions in garnet, corundum, staurolite, quartz, and zircon are 1.00 ± 0.06, 1.07 ± 0.04, 1.09 ± 0.03, 0.29 ± 0.07, and 1.15 ± 0.05 g/cm3, respectively. The mineral features not only in the matrix and but also in garnet from all rock types, isochemical phase diagrams obtained for each bulk rock composition, and Zr-in-rutile thermometry indicate an early eclogite-facies metamorphism (~ 2.5 GPa at 650 °C) and a subsequent nearly isothermal decompression. Zircons yield a wide range of U–Pb ages from 265 to 36 Ma, whereas the dark luminescent cores of the zircons, which contain high-density CO2 inclusions, yield a concordia age of 257 ± 8 Ma. These observations suggest that the dark luminescent zircon cores were formed at the same time as the garnet, corundum, and staurolite that contain high-density CO2 fluid inclusions. Based on the carbonic fluid inclusion isochore and the densities as well as calculated phase diagram, the concordia age can be regarded as recording a prograde stage of metamorphism under conditions lower than 600 °C and 0.7 GPa. Our new data provide the following geological and tectonic constraints: 1) the eruption of basalt occurred before the Permian, possibly related to subduction of the Paleo-Tethys Plate beneath the Indochina craton near the paleo-equator in the Devonian–Carboniferous; 2) strong weathering transformed the basalt to bauxite before the late Permian; 3) the uppermost continental crust, including the bauxites, was subducted in the late Permian due to the collision of the Indochina and South China cratons, leading to eclogite-facies metamorphism; 4) the rocks were then exhumed; and 5) shearing-related thermal events took place until the Paleogene.. |

M. Satish-Kumar, Tetsuo Kawakami, Nobuhiko Nakano, Metamorphism and continental growth: Introduction, Journal of Mineralogical and Petrological Sciences, 111, 47-49, 2016.04, The growth of continents in orogenic belts has always been a key factor in understanding the interaction and co– evolution of Earth’s crust and mantle in time and space. The cyclic process of plate tectonics has been continuously operating throughout much of the Earth’s history, and the continental crust has an important role in evaluating this because the materials accumulated in the continental crust are retained for geologically long durations compared to the oceanic crust. The formation of continental crust is as- sociated with large–scale tectonic processes, and the geo- logical processes involved in its preservation in orogenic belts are therefore important. Because of its close relation with orogeny, continent formation has been episodic and often related to high–temperature (T), and medium to high–pressure (P) metamorphic processes (Brown, 2006). Therefore, a clear understanding of the temporal (t) and spatial evolution (P–T–t evolution) of metamorphic belts is central to the formulation of testable tectonic models. A key turning point in this field of geological sciences has been the progress achieved in micro–analytical tech- niques used in geochronology during the past two decades. Coupled with developments in phase equilibria modeling using internally consistent thermodynamic datasets, this has been instrumental in advancing our understanding of orogeny. By combining these two approaches together, we are now able to provide tight constraints on the time– and length–scales of metamorphism in the order of less than few millions of years within the orogenic cycle.. |
