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...

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...
