The BLM has adopted a two-phase procedure for the integration of geological, energy and minerals (GEM) resources data for suitable/nonsuitable decisions for wilderness study areas (WSA's).

Upper Triassic continental ëtrata of the Chinle Formation, in the Nacimiento Mountains, New Mexico, represent two cycles of fluvial to fluvial-deltaic to marshland-lacustrine sedimentation. Each cycle was initiated by uplift in the southern Ancestral Rocky Mountains and deposited on the local palaeo

Gabbroic dyke and syenitic plug intrusives have been sampled and studied across Huerfano Butte. Petrography and geochemical analyses were performed on selected specimens; from these analyses chemical variation diagrams have been prepared. Crystal Size Distribution analyses have been done on magnetit
