The maximum amplitude of the residual anomaly is about 50 mgal, the maximum gradient 6.6 mg/km, and the average half-width 8.5 km. Analysis of the anomaly leads to a calculation of 23 × 1010 g/cm for its total amount of anomalous mass per unit length. The maximum possible depth to the anomalous mass is 4 km. Geologic interpretation suggests that the anomaly is caused by a large deformed ultramafic intrusion which is serpentinized at very shallow depths. This content is PDF only.
