Crustal structure and faulting of the Gulf of California from geophysical modeling and deconvolution of magnetic profiles

Creator:: Doguin, Pierre
Abstract:: Using gravity, magnetic, bathymetric and seismic refraction data, I have constructed a geophysical cross-section of the central part of the northern Gulf of California. The section exhibits a crustal thickness of 18 km and features an anomalous block of high density lower basement (3.15 g/cm³) which probably resulted from rifting...

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...

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...

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...

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 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...

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...
