Source Parametrization of Earthquakes along Juan de Fuca Transform Boundaries

Creator:: Sapkota, Birat
Abstract:: The Juan de Fuca plate system is what remains of Farallon plate subducting under the continental North American plate. Blanco Transform Fault Zone (BTFZ) consists of a network of strike-slip faults discontinued by pull apart depressions which o↵sets the Juan de Fuca Ridge and the Gorda Ridge. Detailed analysis of...

Sediments and tectonics of the Gorda-Juan de Fuca plate

Creator:: Phipps, James B.
Abstract:: Cores taken from the ridge areas of the Gorda-Juan de Fuca plate have a sedimentation rate that is appropriate for the study of late Quaternary stratigraphy. An analysis of the clay and silt mineralogy of the cores using X-ray diffraction methods and by noting changes in the foraminiferan-radiolarian abundances in...

Helium isotope variations in Juan de Fuca ridge basalts

Creator:: Lupton, John E., Graham, David W., Delaney, John R., and Johnson, H. Paul
Abstract:: We have measured ³He/⁴He ratios and He and Ne concentrations on a suite of 24 basalt glasses from the neovolcanic zone of the Juan de Fuca Ridge (JdFR) from 44.6°N near the Blanco Transform up to 48.0°N on the Endeavour Segment. The helium isotope ratios exhibit a clear geographic variation,...

Seismic anisotropy beneath the Juan de Fuca plate system: Evidence for heterogeneous mantle flow

Creator:: Bodmer, Miles, Toomey, Douglas R., Hooft, Emilie E., Nabelek, John, and Braunmiller, Jochen
Abstract:: Here we use SKS shear wave splitting observations from ocean-bottom seismometer data to infer patterns of mantle deformation beneath the Juan de Fuca plate and its adjoining boundaries. Our results indicate that the asthenosphere beneath the Juan de Fuca plate responds largely to absolute plate motion with an anisotropic layer...

Magnetotelluric observations across the Juan de Fuca subduction system in the EMSLAB project

Creator:: Wannamaker, Philip E., Booker, John R., Filloux, Jean H., Jones, Alan G., Jiracek, George R., Chave, Alan D., Tarits, Pascal, Waff, Harve S., Egbert, Gary D., Young, Charles T., Stodt, John A., Martinez, Mario G., Law, Lawrie K., Yukutake, Takesi, Segawa, Jiro S., White, Anthony, and Green, A.W.
Abstract:: A magnetotelluric (MT)transect has been obtained near latitude 45øN from the active Juan de Fuca Spreading center, across the subduction zone and Cascades volcanic arc, and into the back arc Deschutes Basin region. This paper presents the MT data set and describes its major characteristics as they pertain to the...

Geologic history of the summit of Axial Seamount, Juan de Fuca Ridge

Creator:: Clague, David A., Dreyer, Brian M., Paduan, Jennifer B., Martin, Julie F., Chadwick, William W., Jr., Caress, David W., Portner, Ryan A., Guilderson, Thomas P., McGann, Mary L., Thomas, Hans, Butterfield, David A., and Embley, Robert W.
Abstract:: Multibeam (1 m resolution) and side scan data collected from an autonomous underwater vehicle, and lava samples, radiocarbon-dated sediment cores, and observations of flow contacts collected by remotely operated vehicle were combined to reconstruct the geologic history and flow emplacement processes on Axial Seamount’s summit and upper rift zones. The...

Shallow crustal structure of the caldera of Axial Seamount, Juan de Fuca ridge

Creator:: van Heeswijk, Marijke
Abstract:: An airgun refraction line along the length of the caldera of Axial Seamount as recorded by three Ocean Bottom Seismometers has been analyzed using the tau-zeta inversion technique (Dorman and Jacobson, 1981). Five resulting velocity profiles show that the seismic velocities of the upper 1.4 km of the crust are...
