Abstract
Gravity and total field magnetic intensity data have been collected over three adjacent circular geomorphic features near Jabalpur, presently reported as volcanic vents in the Deccan volcanic province. Bouguer anomaly variation of the order of 1.2 to 2 mGal in a 1.5 km long profile, and total field magnetic anomaly of the order of -900 to 1400 nT have been observed. The gravity variation does not give any reflection of underlying deep seated high density material; and there are no isolated or elliptical magnetic anomalies that can be attributed to the presence of deep seated anomalous source like a volcanic vent. The basement depth values as determined by Werner deconvolution technique corresponding to the three circular geomorphic features is 51.7, 57.6 and 75 m.
