Publicly available (also known as precompetitive) geoscience data is vital not just to further our understanding of surface and subsurface geology and for other crucial areas of research such as natural hazards, environmental research, and agriculture but is especially crucial to support and derisk mineral exploration and to enable efficient and effective resource discovery and...

The brick-red Moenkopi Formation, exposed in the valley of the Little Colorado River in northern Arizona, was deposited along western equatorial Pangea during the Early to Middle Triassic Period. The Moenkopi Formation has been valued by humans for millennia as a building stone and lithic canvas to record intricate carvings. The pueblo walls at Wupatki...

The Proterozoic crust of southern Laurentia has been considered an archetype of continental growth via the accretion of exotic crustal fragments for over 30 years. In a broadly accepted model, Laurentia grew by the sequential addition of the ca. 1.8-1.7 Ga Yavapai and ca. 1.7-1.6 Ga Mazatzal provinces. These provinces were originally defined in central...

The U.S. and other countries are making major investments to evaluate the deep-subsurface for storage and energy options to meet growing demands for clean and alternative energy, energy resiliency, and management of energy-related wastes. In Arizona, deep, subsurface geology has excellent potential to accommodate the energy transition through salt cavern gas storage, energy byproduct disposal...

The famous red rocks of the Mogollon Escarpment, from Sedona to White River, have traditionally been assigned the name Supai, correlating these rocks with the Supai Group of the Grand Canyon. The underlying limestone-bearing units have traditionally been called the Naco Formation in reference to the Naco Group of southeastern Arizona. Several workers, however, have...

Critical and strategic minerals have been buzzy terms in the news in the last few years, but have an often-ignored history that stretches clearly back to World War I. Critical mineral topics have been receiving bipartisan support from Congress as sourcing them addresses multiple needs. For one, in the United States, we are dependent on...
