“…The 'clockwise' (orange) vs. 'anticlockwise' (blue) notation is defined on the basis of pressure increasing up the page and temperature increasing from left to right and indicates that PeT path shape is independent of timescale. metamorphism has been classified, ranging from 'short', of the order of approximately <5e40 Myr (Table 2; Schmitz and Bowring, 2003;Baldwin and Brown, 2008;Clark et al, 2009;Leite et al, 2009;Santosh et al, 2009cSantosh et al, , 2012Santosh et al, , 2013Schmitz et al, 2009;Brandt et al, 2011;Cutts et al, 2011a;Galli et al, 2011;Giustina et al, 2011;Jöns and Schenk, 2011;Orejana et al, 2011;Guo et al, 2012;Xiang et al, 2012;Nakano et al, 2013;Bhowmick et al, 2014;; and 'long', of the order of approximately !40 Myr (Baba et al, 2010;Das et al, 2011;Korhonen et al, 2011;Smithies et al, 2011;Drüppel et al, 2013;Korhonen et al, 2013b;Walsh et al, 2014). The timescale of UHT metamorphism for a particular locality/terrane will be dependent on the longevity of the heat source as well as numerous other factors discussed earlier (see section 8) that comprise the total geologic and tectonic system (Brown and Korhonen 2009).…”

a b s t r a c tUltrahigh temperature (UHT) metamorphism is the most thermally extreme form of regional crustal metamorphism, with temperatures exceeding 900 C. UHT crustal metamorphism is recognised in more than 50 localities globally in the metamorphic rock record and is accepted as 'normal' in the spectrum of regional crustal processes. UHT metamorphism is typically identified on the basis of diagnostic mineral assemblages such as sapphirine þ quartz, orthopyroxene þ sillimanite AE quartz and osumilite in MgeAlrich rock compositions, now usually coupled with pseudosection-based thermobarometry using internally-consistent thermodynamic data sets and/or Al-in-Orthopyroxene and ternary feldspar thermobarometry. Significant progress in the understanding of regional UHT metamorphism in recent years includes: (1) development of a ferric iron activityecomposition thermodynamic model for sapphirine, allowing phase diagram calculations for oxidised rock compositions; (2) quantification of UHT conditions via trace element thermometry, with Zr-in-rutile more commonly recording higher temperatures than Ti-in-zircon. Rutile is likely to be stable at peak UHT conditions whereas zircon may only grow as UHT rocks are cooling. In addition, the extent to which Zr diffuses out of rutile is controlled by chemical communication with zircon; (3) more fully recognising and utilising temperature-dependent thermal properties of the crust, and the possible range of heat sources causing metamorphism in geodynamic modelling studies; (4) recognising that crust partially melted either in a previous event or earlier in a long-duration event has greater capacity than fertile, unmelted crust to achieve UHT conditions due to the heat energy consumed by partial melting reactions; (5) more strongly linking UePb geochronological data from zircon and monazite to PeT points or path segments through using Y þ REE partitioning between accessory and major phases, as well as phase diagrams incorporating Zr and REE; and (6) improved insight into the settings and factors responsible for UHT metamorphism via geodynamic forward models. These models suggest that regional UHT metamorphism is, principally, geodynamically related to subduction, coupled with elevated crustal radiogenic heat generation rates.Ó 2014, China University of Geosciences (Beijing) and Peking University.

“…However, several studies have shown zircon growth and resetting of U-Pb isotope system of older zircons during different stages of metamorphism (Fraser et al, 1997;Roberts and Finger, 1997;Schaltegger et al, 1999;Hoskin and Black, 2000;Hermann and Rubatto, 2003;Y.-B. Wu et al, 2006;Geisler et al, 2007;Gerdes and Zeh, 2009;Xia et al, 2009;Chen et al, 2011;Page et al, 2013;Bhowmik et al, 2014). Therefore all the U-Pb ages derived from metamorphic zircons in high-grade rocks are unlikely to correspond with the time of peak metamorphism and many of them were suggested to represent the time of post-peak metamorphism (Roberts and Finger, 1997;.…”

“…The variation in metamorphic parameters combined with the ages of accessory mineral inclusions in the various generations of garnet can be used to contain the timing of metamorphism polymetamorphic complexes. Previous publications show good consistency between the results obtained by the in situ Th-U-Pb method and the isotope data (Anderson et al, 2013;Browmik et al, 2014;Cutts et al, 2010Cutts et al, , 2013Likhanov et al, 2013dMorrissey et al, 2014;Suzuki and Kato, 2008). Despite its slightly lower precision relative to conventional isotope analyses, in situ Th-U-Pb microprobe chemical age determinations of radioactive mineral inclusions in metamorphic minerals can be rather informative method to reconstruct the timing and duration of metamorphic events in areas with a complex polyphase history.…”

Studies of gneisses from the Yenisei regional shear zone (YRSZ) provide the first evidence for Mesoproterozoic tectonic events in the geologic history of the South Yenisei Ridge and allowed the recognition of several stages of deformation and metamorphism spanning from Late Paleoproterozoic to Vendian. The first stage (~1.73 Ga), corresponding to the period of granulite-amphibolite metamorphism at P = 5.9 kbar and T = 635 °C, marks the final amalgamation of the Siberian craton to the Paleo-Mesoproterozoic Nuna supercontinent. During the second stage, corresponding to a hypothesized breakup of Nuna as a result of crustal extension, these rocks underwent Mesoproterozoic dynamic metamorphism (P = 7.4 kbar and T = 660 °C) with three peaks at 1.54, 1.38, and 1.25 Ga and the formation of high-pressure blastomylonite rocks in shear zones. Late-stage deformations during the Mesoproterozoic tectonic activity in the region, related to the Grenville-age collision processes and assembly of Rodinia, took place at 1.17-1.03 Ga. The latest pulse of dynamic metamorphism (615-600 Ma) marks the final stage of the Neoproterozoic evolution of the Yenisei Ridge, which is associated with the accretion of island-arc terranes to the western margin of the Siberian craton. The overall duration of identified tectonothermal processes within the South Yenisei Ridge during the Riphean (~650 Ma) is correlated with the duration of geodynamic cycles in the supercontinent evolution. A similar succession and style of tectonothermal events in the history of both the southern and the northern parts of the Yenisei Ridge suggest that they evolved synchronously within a single structure over a prolonged time span (1385-600 Ma). New data on coeavl events identified on the western margin of the Siberian craton contradict the hypothesis of a mantle activity lull (from 1.75 to 0.7 Ga) on the southwestern margins of the Siberian craton during the Precambrian. The synchronous sequence and similar style of tectonic events on the periphery of the large Precambrian Laurentia, Baltica, and Siberia cratons suggest their spatial proximity over a prolonged time span (1550-600 Ma). The above conclusion is consistent with the results of modern paleomagnetic reconstructions suggesting that these cratons represented the cores of Nuna and Rodinia within the above time interval.
