The Arunta Region of Central Australia exposes well-preserved Proterozoic geology. Fold-and-thrust belts, gravity-driven nappe complexes, and gneiss domes record a long history of orogenic deformation.
The Broken Hill Block of western New South Wales exposes deeply exhumed, deformed Palaeoproterozoic metasediments and high-grade gneisses. The area is a UNESCO Global Geopark.
Field sites in southern California include the Big Maria Mountains and the Mojave Desert. Both areas preserve a record of Mesozoic contractional deformation along the Cordilleran margin, with metamorphic core complexes, fold belts, and good exposures spanning Laramide contraction through Basin-and-Range extension.
Montana's Rocky Mountain front preserves classic fold-and-thrust belt geometry, with Precambrian basement rocks thrust eastward over Phanerozoic sediments. The topography is a direct expression of the underlying structural architecture.
