Gravity and magneitc anomalies in the San Juan Basin area

Regional gravity and magnetic maps that include the San Juan Basin area (e.g., Cordell, 1984; Keller and Cordell, 1984) demonstrate that there are many significant anomalies present. Here, we present a series of relatively detailed maps that enhance these anomalies and briefly comment on their geological significance. Our primary goal is to present these maps for the use of those interested in this region and to illustrate their utility.
