The Jurassic Todilto Formation Of New Mexico, Henry O. Ash
Earth and Planetary Sciences ETDs
The Todilto formation of New Mexico is a widespread and distinctive Jurassic unit confined to the northern one-half of the State and adjacent parts of Arizona and Colorado. It consists of a lower Limestone member and an upper Gypsum member. The Gypsum member also contains some limestone. The two members are not coextensive in area. Both are present in the central part of the area in which the formation is found, but the Limestone member extends far beyond the limits of the Gypsum member.
