Uranium resources of northwestern New Mexico

Pennsylvanian to Jurassic eolian transportation systems in the western United States

“…There is a fair amount of variation in the resultants but it is not consistent in most areas and, instead, strongly opposed resultants may lie close to each other. A large marine embayment (or lake) represented by the Todilto Limestone Member of the Wanakah Formation stretched across north-central New Mexico (Hilpert, 1969) and probably connected with the Sundance seaway through a narrow strait that most likely was in west-central Colorado (Ridgley, 1984). The embayment only existed for a short time during deposition of a small part of the middle Entrada so anomalous wind patterns that might have been related to the embayment would only have been present for a short time.…”

Mineral resources of the San Pedro Parks Wilderness and vicinity, Rio Arriba and Sandoval Counties, New Mexico

“…A reconnaissance geologic map made by Northrop and Wood (1946) includes San Pedro Mountain and environs. Studies were made of existing and potential deposits of manganese by Farnham (1961), of copper by Soule (1956), and of uranium by Brown (1955) and by Hilpert (1969).…”

“…Copper (Schrader, 1910;Soule, 1956), coal (Gardner, 1909), gypsum (Shaler, 1907), manganese (Farnham, 1961), and uranium (Brown 1955;Hilpert, 1969) have been mined from adjacent areas.…”

Geology and ore deposits of the Section 23 Mine, Ambrosia Lake District, New Mexico

“…The structural and stratigraphic setting of the Grants mineral belt has been described adequately elsewhere (Kelly, 1963;Moench and Schlee, 1967;Hilpert, 1969;Santos, 1970) and will only be summarized briefly here.…”
