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...

Full Text:: INTERPRETATION OF MAGNETIC ANOMALIES OBSERVED IN NORTH-CENTRAL CALIFORNIA Abstract approved: Richard W. Couc

Creator:: Zamora, Osvaldo Sanchez
Abstract:: Geophysical surveys in the Gulf of California provided the data to construct contour maps of bathymetry, free-air anomalies and total field magnetic anomalies for the area north of 27° N. Major faults such as the Ballenas- Salsipuedes, Tiburón, Guaymas, and the South Cerro Prieto are clearly observable on these maps....

Creator:: Johnson, Stephen Hans
Abstract:: Seismic refraction measurements along two unreversed lines indicate that the earth's crust is 26 km thick in southeastern Alaska and 30 km thick along the Inside Passage of British Columbia. The crust in southeastern Alaska, north of Dixon Entrance, consists of a layer 9 km thick with a seismic velocity...

Creator:: Whitsett, Robert Manning
Abstract:: A free-air gravity anomaly map of the continental margin of Peru between 12° and 18° S. Lat. shows a -110 to -220 mgl anomaly associated with the Peru-Chile Trench, a -60 mgl anomaly over the Pisco Basin on the continental shelf, and -120 mgl anomaly over the Mollendo (or Arequipa)...
