The structure of the Neoarchean Yilgarn Craton is dominated by craton-scale high-strain zones, mostly associated with highly-deformed elongate granitic bodies and transposed greenstone belts. These shear zones developed during widespread and prolonged magmatic activity that led to a nearly complete reworking of the felsic continental crust. Recent structural works show that some of these shear zones assisted the emplacement of c. 2700-2660 Ma granite plutons during Neoarchean transpression, allowing the migration of lower crustal melts towards sink in the upper crust. Some of these shear zones are major and possibly long-lived structures juxtaposing different terranes. Geochronology and isotopic data suggest that these terranes may represent microcratons that were progressively amalgamated producing larger crustal blocks. However, little is known about the structural evolution of these shear zones, and therefore the modality, kinematics, tectonic significance and timing of such “amalgamation episodes” between different terranes are still the subject of a long-standing debate. Hence, tectonic models for the assembly of the Yilgarn Craton range from arc-accretion to autochthonous (i.e. plume-dominated) models. Moreover, published tectonic models are based on studies in the eastern half of the craton, where younger rocks are exposed. Therefore, large scale models for the evolution of the Yilgarn Craton have been built in the absence of a comprehensive understanding of its evolution pre-dating 2700 Ma. In this talk I will summarize some results of five years of structural mapping in the western half of the craton (i.e. in the Youanmi Terrane), where pre-2700 Ma rocks and structures are exposed, aiming to provide some first-order constraints to the Neoarchean evolution of the Yilgarn Craton.
