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...

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...

Structures of the continental margin of Central America from northern Nicaragua to northern Panama

Creator:: Victor, Linda
Abstract:: Gravity and seismic data obtained by the geophysical group at Oregon State University on the R/V YAQUINA during 1969, 1971, and 1973 plus other available data over the area just west of Nicaragua and Costa Rica indicate the tectonic complexity of the region. Gravity measurements show negative free-air anomalies over...

Crustal structure of the Baja Peninsula between latitudes 22 ̊N and 25 ̊N

Creator:: Huehn, Bruce
Abstract:: Geophysical data collected in 1975 and 1976 reveal major crustal and tectonic elements of the continental margin of southern Baja California. Gravity, magnetic, seismic reflection and bathymetric data show seaward extension of the islands enclosing Magdalena and Almejas Bays. A seismic reflection profile, oriented approximately normal to the trend of...

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...

Gravity and structure of the Pacific continental margin of Central Mexico

Creator:: Sanchez Zamora, Osvaldo
Abstract:: Data collected by personnel of the Geophysics Group at Oregon State University and the Instituto Oceanografico of the Direccion General dé Oceanografia are used to construct a free-air anomaly map for the central part of the Pacific continental margin of Mexico, which shows the gravity expression of major structural features...
