Geologic map of the central part of the San Francisco Volcanic Field, north-central Arizona

The geologic map of the central part of the San Francisco volcanic field (called the Central map area) is one of five adjoining geologic maps (fig. 1) prepared under the Geothermal Research Program of the U.S. Geological Sruvey as a basis for interpreting the history of magmatic activity in the volcanic field. The San Francisco field, which is largely Pliocene and Pleistocene in age, is in norther

Geologic map of the eastern equatorial region of Mars

The Mariner 9 mission in the early 1970’s provided the first comprehensive view of the geology of Mars (McCauley and others, 1972, Masursky, 1973) and led to the derivation of the first global geologic map (Carr and others, 1973). These preliminary studies were followed by more comprehensive mapping coordinated with the U.S. Geological Survey. Thirty quadrangles at a scale of 1:5,000,000 were prod
