Abstract

A total of 570 gravity stations were established within an area of about 1,000 square miles south of the common corner of Colorado, Utah, Arizona, and New Mexico. The Bouguer gravity anomaly pattern apparently is unrelated to the disposition of minette plugs inasmuch as there probably is little contrast in density between the conduit filling and the surrounding sedimentary rock. Gravity contours associated with an underlying dense mass within the Precambrian basement parallel the Boundary Butte anticlinal structure. The steep gravity anomaly gradient near the southeast corner of the area probably follows the buried, steeply dipping or faulted edge of the Defiance uplift.
