Long wavelength gravity anomalies and implications concerning a descending lithospheric slab in the Pacific Northwest

Creator:

MacFarlane, William Thomas

Abstract:

The thermal regime of a postulated descending lithospheric slab is calculated. The gravity anomaly associated with such a structure is large in amplitude and long in wavelengh. Observed free-air gravity anomalies in the Pacific Northwest do not indicate a gravitational effect due to a descending slab. Two hypothetical compensation models...
