<p style="text-indent:.5in"><span style="font-size:11pt"><span style="line-height:150%"><span style="font-family:Aptos,sans-serif"><span style="font-size:12.0pt"><span style="line-height:150%"><span new="" roman="" style="font-family:" times="">We measured peak metamorphic temperatures using Raman spectroscopy of carbonaceous material (RSCM) thermometry, and we collected quartz crystallographic preferred-orientation (CPO), thin section-scale finite strain, and shear‐sense datasets from samples collected along these transects. We integrate new and published data to resolve spatial trends in peak and deformation temperature, finite strain magnitude, the intensity of CPO development, and kinematics across the length, width, and height of the TMN. Our work builds upon the temperature and structural datasets of Long et al. (2020) to provide a comprehensive investigation that spans the full spatial extent of the TMN. Whereas our previous work focused on the TMN exhumation history, the present study focuses on TMN emplacement. We go on to explore the implications of these datasets for testing published model predictions for the construction of UHP terranes, and for elucidating the structural and metamorphic evolution of the TMN.</span></span></span></span></span></span></p>
