Interpretation of basement structures and geophysical anomalies in the southeastern Colorado Plateau
— Richard D. Jenkins and G. Randy Keller
A preliminary analysis of basement structures in the southeastern portion of the Colorado Plateau was conducted using gravity, drilling and aeromagnetic data. A variety of gravity maps were constructed which delineate the dominant northeast trends which are at least mostly due to Precambrian structures and northwest trends which are mostly the result of Pennsylvanian orogenic activity. Basement heterogeneities were studied via computer modeling of the gravity data. These results indicate basement features which are interpreted to be the result of igneous activity exist beneath the Defiance uplift. The results obtained to date certainly attest to the complexity of the basement in the southeastern Colorado Plateau.
