On the basis of gravity modeling, genesis of the Sudbury Structure has been attributed to either a magmatic origin (having a dense hidden differentiate zone) or a meteorite impact origin (there being no dense hidden mass). The difference between the two gravity models centers on the problem of regional-residual by: GEOPHYSICAL WELL-LOG ANALYSIS OF FRACTURED CRYSTALLINE ROCKS AT EAST BULL LAKE, ONTARIO, CANADA By F.L.
