Recent research highlights
My original field of expertise is metamorphic petrology and I have developed a special interest on the evolution of crust in large hot orogens.
Recent/current research focuses on:
Recent/current research focuses on:
- high-T metamorphic processes and anatexis in the middle to lower crust in large hot orogens (and in other high-T environments)
- earlier features that may have influenced the development of an orogen
- reassessment of the Grenville orogen
Research on the hinterland of the central Grenville Province /Why ?
Recent and current work on the Laurentian margin
- crustal evolution between 1.6 and 1.1 Ga in the central Grenville (e.g. Dunning & Indares 2010; Groulier et al. 2018, 2020 ).
- protolith identification and tectonic setting of ~1.2 Ga volcaniclastic sequences, metamorphosed under granulite facies conditions during the Grenvillian orogeny (e.g. Indares & Moukhsil 2013; Lasalle et al. 2013; Hindemith et al. 2017).
-- U-Pb geochronology in collaboration with Dunning, MUN
-- Groulier et al. (2018a,b): in collaboration with MRN, Quebec.
*** evolution of the SE laurentian margin from 1.50 ti 1.35 Ga- Daniel et al. (2023), Indares et al. (2023).
- The Mesoproterozoic (~1.0 Ga) Grenville Province in the Eastern Canadian Shield, commonly compared to the modern Himalaya-Tibet system, was developed on the long-lived Andean -style margin of Laurentia and is part of a global-scale network of hot to ultra-hot orogens of similar age.
- it provides a record of (a) crustal formation processes in active margins; (b) crustal evolution in a continental collision setting; and (c) orogenic processes in middle to lower crust, which is not accessible in modern analogues.

Recent and current work on high-T metamorphism in large hot orogens- thematic studies & applications to the Grenville
Widespread exposure of granulite-facies, deep to relatively shallow levels of the orogenic infrastructure in the central Grenville, makes it an ideal laboratory to investigate high-T metamorphic processes and anatexis at wide range of depths.
- Metamorphic diversity across the hinterland: P–T paths, tectonic implications (e.g. Indares et al. 2008; Lasalle & Indares 2014; Patrick & Indares 2017); and 1st order time constrains (Dunning & Indares 2010; Lasalle et al. 2014), using aluminous granulites.
For this research component, were used diverse and novel imaging of microstructures (e.g. Kendrick & Indares 2018a,b) integrated with thermodynamic modelling, and U-Pb geochronology.
- garnet petrochronology on the high-P segment of central Grenville- an example of localized crustal thickening against rigid Archean lithosphere (Lotout et al. 2023).
- Relations between metamorphism and synorogenic magmatism (Groulier et al. 2018; & Yip in progress; Fonseca-Martinez, in progress).
