This book was released on 1968 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent work provides the basis for establishing a stratigraphic column in the Santa Rita Mountains of Santa Cruz and Pima Counties of southeastern Arizona. Thirteen formations of this column are here defined and one is revised. One new formation is a Precambrian granodiorite. Ten new formations are Mesozoic units that include plutonic, volcanic, and continental sedimentary rocks. The revised formation is the Upper Cretaceous Fort Crittenden Formation of Stoyanow (1949), dominantly a sedimentary unit. Two new formations are volcanic and sedimentary rocks of Tertiary age. Many radiometric dates supplement the sparse fossil record in corroborating or redefining the ages that had been assigned to many units on the basis of their geologic relations and in establishing the ages of other units.
