Crustal structure of the northwestern continental margin of the Indian subcontinent from gravity and magnetic data

Creator:: Soofi, Muhammad Asif
Abstract:: The continental margin off the coast of Pakistan between the Murray ridge and the Gulf of Cambay has been studied in this work using gravity, magnetic and bathymetric data. Two dimensional gravity and magnetic models based on free-air gravity and residual magnetic data are developed along a north-south profile off...

Crustal structures and tectonism in southeastern Alaska and western British Columbia from seismic refraction, seismic reflection, gravity, magnetic, and microearthquake measurements

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...

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...

Geologic structure of the western continental margin of south central Baja California based on seismic and potential field data

Creator:: Coperude, Shane Patrick
Abstract:: Marine geophysical data from the continental margin of Baja California and the Gulf of California, and geological and geophysical data from the Baja California Peninsula and mainland Mexico, outline the major geologic and tectonic features of the Baja California Peninsula and the surrounding areas from 24.5° N. Lat. to 27.5°...

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....

Gravity anomalies and their structural implications for the southern Oregon Cascade Mountains and adjoining Basin and Range province

Creator:: Veen, Cynthia A.
Abstract:: Gravity measurements made during 1979 and 1980, combined with existing gravity measurements, provide data for the interpretation of upper crustal structures relevant to the assessment of the geothermal potential of south-central Oregon. West of Upper Klamath Lake, free-air gravity anomalies trend north-south and average near 35 mgals. East of Upper...
