Gravity and magnetic data outline a broad anomaly near Walmonie Site, Nye County, Nevada. A positive 15-nGal gravity anomaly with a steep western gradient and a broad magnetic anomaly coincident with the gravity high characteristize the area. Two-dimensional computer models of the gravity data were made using magnetic, seismic, and electric data as indepedent constraints. The models indicate the presence of a shallow, relatively high density body of 2.65 kg m-3 buried near Wahmonie Site. Aeromagnetic and ground magnetic data also indicate the presence of a large, shallow body. Two smaller local magnetic highs that occur along a magnetic prominence extending northward from the broad anomaly directly correlate to granodiroite outcrops. This indicates that the main anomaly is produced by a large shallow intrusion. |
