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...

Structure of the Panama Basin from marine gravity data

Creator:

Barday, Robert James

Abstract:

In order to quantitatively examine the crustal structure of the Panama Basin without the benefit of local seismic refraction data, the following assumptions were made: (1) No significant lateral changes in density take place below a depth of 50 km. (2) The densities of the crustal layers are those of...
