Curie-point isotherm mapping and interpretation from aeromagnetic measurements in the northern Oregon Cascades

Creator:: Foote, Robert W.
Abstract:: During the summer and fall of 1982, personnel from the Geophysics Group in the School of Oceanography at Oregon State University conducted an aeromagnetic survey in the northern Oregon Cascades to assess geothermal potential and study the thermal evolution of the Cascade volcanic arc. Total field and low-pass filtered magnetic...

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...

Crustal structure of the Tehuantepec Ridge and adjacent continental margins of southwestern Mexico and western Guatemala

Creator:: Woodcock, Stephen Frederick
Abstract:: A free-air gravity anomaly map of the area between 10°-17°N and 90°-101°W shows distinctive positive and negative anomalies which parallel the Tehuatepec Ridge. The positive anomaly approximately overlies the topographic expression of the ridge. On the wide continental shelf southeast of the Gulf of Tehuantepec a positive gravity anomaly with...

Crustal structure of the Continental Borderland and the adjacent portion of Baja California between latitudes 30⁰N and 33⁰N

Creator:: Plawman, Thomas Leon
Abstract:: Gravity, magnetic and seismic data indicate that the oceanic crust is 9.7 km thick west of the Continental Borderland. The top of the mantle is about 12 km deep under the Borderland, and deepens to 27 km beneath the Peninsular Ranges of Baja California. The mantle is about 20 km...

Crustal structure and thermal gradients of the northern Gulf of California determined using spectral analysis of magnetic anomalies

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....

The crustal structure and tectonic framework of the Gulf of Panama

Creator:: Briceno-Guarupe, Luis Alberto
Abstract:: Gravity and magnetic data from cruises by the R/V Yaquina in 1973 and the R/V Wecoma in 1975 provide new data that make possible the construction of a map of the free-air gravity anomalies at sea and simple Bouguer anomalies on lano in Panama, western Colombia, and the eastern Panama...

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...

Analysis and interpretation of magnetic anomalies observed in north-central California

Creator:: Huppunen, JoAnne L.
Abstract:: To assist in the assessment of the geothermal potential of north-central California and to aid in defining the geologic transitions between the physiographic provinces of the Klamath Range, the Cascade Range, the Modoc Plateau, the Great Valley, and the Sierra Nevada Range, personnel from the Geophysics Group in the College...
