A small, illustrated section is devoted to quarrying, finishing, and mounting stone. The historical changes in architecture combine classical with modern styles to provide startling contrasts. The many colorful photographs are accompanied by detailed descriptions of the stone and other materials used in the buildings to provide a beautiful, entertaining, and informative look at Albuquerque downtown. The Florida Mountains are an eastward-tilted Basin and Range fault block about 15 miles southeast of Deming. The mountains are surrounded by a broad bajada that slopes gently into the Mimbres Basin.
Sediments conceal the range-bounding faults except at the northwest end.
Ephemeral streams are continuing the erosive processes that have reduced the exposed bedrock area to less than one-half of its initial size. Terminology, interpretations, and ideas in this report represent revisions from Clemons' earlier publications. It is bounded on the west by Neogene downfaulted and downwarped basins of the Rio Grande depression and, on the east, by broad Laramide basins that have sharply folded western limbs. The uplift was modified in Neogene time by local igneous-intrusive doming and normal faulting related to the Rio Grande rift. A main objective of the study was to determine, document, and paleontologically date the highly complex variations in thickness and lithofacies that occur in Lower Pennsylvanian through Lower Permian formations between the Pecos shelf and the deep northern Taos trough and Rainsville trough.
