  <dc:description>An anomaly about 300 gammas in amplitude has been observed in data from an aerial magnetic survey flown over parts of Duval, Live Oak, McMullen, and Webb Counties, Tex. A two-and-one-half-dimensional model was used to iterpret the data, and the anomaly is apparently caused by a large mafic body centered near 28?10'N and 98?22'W, with an area of about 1800 km2 at a depth of 10 km.</dc:description>
