An Investigation of the Applicability of Gravimetric and Magneto metric Methods of Geophysical Prospecting

CIM Bulletin, 1949


This paper is an account of an investigation made by the Dominion Observatory with a gravity meter and magnetometer over sulphide concentrations at East Sullivan, Val d'Or, Que., in June, 1947. The topographic relief over the area does not exceed 20 feet . The overburden varies from 0 co 50 feet . The west orebody had been outlined by extensive drilling. The average density contrast between the sulphide body and surrounding rocks is 0.5.
