Data for: Tectono-metamorphic evolution of Big Thompson Canyon region, Colorado Rocky Mountains, USA

Using microstructural, foliation intersection axes (FIAs), thermodynamic modeling (McNCKFMASH) and chemical relationships, this research investigates in detail the metamorphic and deformation processes and the progression in the distribution of various index minerals phases (garnet, staurolite, andalusite and cordierite) in the Big Thompson Canyon region, Colorado Rocky Mountains, USA. This region forms part of a Proterozoic orogenic belt in the southwestern USA and provides a classic example of a large high-T-low-P terrane.
