The foremost purpose of this report is to outline the general geology and geomorphology of the mapped area. Secondarily, the relationship of the Santa Fe formation of late Tertiary age to older strata is explored. Presence of basalts and other volcanics in the Santa Fe formation is shown. Evidence indicating the probable contemporaneity of part of the Chicoma volcanic group and of the Santa Fe formation is discussed.

The thesis area lies along the eastern base of North Ridge which forms the northern part of the Caballo Mountains. This ridge rises abruptly, about 1,500 feet, above the considerably dissected lowland on which the area is located. The lowland lies near the head of Mescal Canyon and is dissected into the ridges and valley with a relief as much as 300 feet. The drainage is east and north into Mescal Canyon (Pl.2) which joins the Rio Grande just below Elephant Butte Dam.

Geology Of The Sierra De Santa Rita, Zacatecas, Mexico, Zoltan Decserna
Earth and Planetary Sciences ETDs
Information concerning the southern extent of the Mexican geosyncline was desired with the mapping of Sierra de Santa Rita, near Concepción del Oro, Zacatecas, in northern Mexico. Three Upper Jurassic and six Cretaceous formations were mapped, within which lithology and changes in thickness do not reflect proximity of this area to ancient shore lines. The first description of the Huizachal formation in northern Zacatecas is given.

When the writer was examining some of the volcanic plugs near Cabezon, New Mexico in the spring of 1951, he discovered in Plug No. 5 (Pl. 2, D.W. Johnson, 1907) some unusual, large vitreous inclusions.
