“…Geodynamic modeling has been used to address important processes such as slab breakoff (Gerya et al, 2004;Duretz et al, 2011), shallow subduction (van Hunen et al, 2004;Currie and Beaumont, 2011), ridge subduction (Groome and Thorkelson, 2009), deep crustal flow (Royden et al, 1997;Clark and Royden, 2000;Beaumont et al, 2004), delamination (Gray and Pysklywec, 2012;Ueda et al, 2012), intraplate orogenesis (Neil and Houseman, 1999;Pysklywec and Beaumont, 2004;Gorczyk et al, 2012Gorczyk et al, , 2013Gorczyk and Vogt, 2014), and exhumation of UHPM terranes (Gerya et al, 2002;Warren et al, 2008;Beaumont et al, 2009;Sizova et al, 2012). Geodynamic modeling has also been used to evaluate crustal growth at active continental margins (Vogt et al, 2012;Zhu et al, 2013) and to understand the links between metamorphism and tectonics (Jamieson and Beaumont, 1988;Sandiford and Powell, 1990;Jamieson et al, 2002Jamieson et al, , 2004Gerya and Stockhert, 2006;Li et al, 2010). Of course, geodynamic modeling has also been applied to the problem of Precambrian geodynamics (van Thienen et al, 2004;van Hunen and van den Berg, 2008;Sizova et al, 2010Sizova et al, , 2014Gerya, 2014;Johnson et al, 2014) and tectonics (Perchuk and , and the formation of the cratonic roots composed of strongly depleted sub-continental mantle lithosphere (Gray and Pysklywec, 2010;…”

a b s t r a c tIn the early 1980s, evidence that crustal rocks had reached temperatures >1000 C at normal lower crustal pressures while others had followed low thermal gradients to record pressures characteristic of mantle conditions began to appear in the literature, and the importance of melting in the tectonic evolution of orogens and metamorphicemetasomatic reworking of the lithospheric mantle was realized. In parallel, new developments in instrumentation, the expansion of in situ analysis of geological materials and increases in computing power opened up new fields of investigation. The robust quantification of pressure (P), temperature (T) and time (t) that followed these advances has provided reliable data to benchmark geodynamic models and to investigate secular change in the thermal state of the lithosphere as registered by metamorphism through time. As a result, the last 30 years have seen significant progress in our understanding of lithospheric evolution, particularly as it relates to Precambrian geodynamics.EoarcheaneMesoarchean crust registers uniformly high T/P metamorphism that may reflect a stagnant lid regime. In contrast, two contrasting types of metamorphism, eclogiteehigh-pressure granulite metamorphism, with apparent thermal gradients of 350e750 C/GPa, and granulite eultrahigh temperature metamorphism, with apparent thermal gradients of 750e1500 C/GPa, appeared in the Neoarchean rock record. The emergence of paired metamorphism is interpreted to register the onset of one-sided subduction, which introduced an asymmetric thermal structure at these developing convergent plate margins characterized by lower T/P in the subduction channel and higher T/P in the overriding plate. During the Paleoarchean to Paleoproterozoic the ambient mantle temperature was warmer than at present by w300e150 C. Although the thermal history of Earth is only poorly constrained, it is likely that prior to c. 3.0 Ga heating from radioactive decay would have exceeded surface heat loss, whereas since c. 2.5 Ga secular cooling has dominated the thermal history of the Earth. The advent of paired metamorphism is consistent with other changes in the geological record during the Neoarchean that are best explained as the result of a transition from a stagnant lid to subduction and a global plate tectonics regime by c. 2.5 Ga. This interpretation is supported by results from 2-D numerical experiments of oceanic subduction that demonstrate a change to one-sided subduction is plausible as upper mantle temperature declined to <200 C warmer than at present during the late NeoarcheanePaleoproterozoic. This is the beginning of the Proterozoic plate tectonics regime.At 1.0 Ga the ambient mantle temperature was still w150e100 C warmer than at present. Continued secular cooling caused a transition to cold subduction registered in the crustal record of metamorphism by the first appearance of blueschist and high to ultrahigh pressure metamorphism during the Neoproterozoic. Results of 2-d numerical experiments of continental collision demon...

“…Last but not least, crustal growth in our models is assumed to be fully controlled by surface volcanism, whereas on Earth intrusive crustal accretion in form of plutons is dominant, which calls for the use of more realistic melt emplacement algorithms (e.g. Vogt et al, 2012).…”

“…Hence, melt exceeding a predefined melt threshold of (i.e., Schmeling et al, 2008) M max ¼ 4% is extracted and only a non-extractable amount of melt M min ¼ 2% remains at the source (Nikolaeva et al, 2008;Sizova et al, 2010;Gerya and Meilick, 2011;Vogt et al, 2012).

“…Due to the resolution limitations of three-dimensional modeling, the modeling has been conducted in 2D. 2D not only allows for implementation of visco-plasticity and mineral phase transformation but also related melting/melt extraction processes (Vogt et al, 2012), which require higher resolution than 3D allows for. Nevertheless, we are attempting to model a complex geological history and a lithospheric architecture (including a cratonic triplejunction) that would clearly be affected by 'out of plane' (3D) processes.…”

a b s t r a c tThe Musgrave Province developed at the nexus of the North, West and South Australian cratons and its Mesoproterozoic evolution incorporates a 100 Ma period of ultra-high temperature (UHT) metamorphism from ca. 1220 to ca. 1120 Ma. This was accompanied by high-temperature A-type granitic magmatism over an 80 Ma period, sourced in part from mantle-derived components and emplaced as a series of pulsed events that also coincide with peaks in UHT metamorphism. The tectonic setting for this thermal event (the Musgrave Orogeny) is thought to have been intracontinental and the lithospheric architecture of the region is suggested to have had a major influence on the thermal evolution. We use a series of two dimensional, fully coupled thermo-mechanical-petrological numerical models to investigate the plausibility of initiating and prolonging UHT conditions under model setup conditions appropriate to the inferred tectonic setting and lithospheric architecture of the Musgrave Province. The results support the inferred tectonic framework for the Musgrave Orogeny, predicting periods of UHT metamorphism of up to 70 Ma, accompanied by thin crust and extensive magmatism derived from both crustal and mantle sources. The results also appear to be critically dependent upon the specific location of the Musgrave Province, constrained between thicker cratonic masses.
