    OCEAN/ESS 410 Lab 3. The Juan de Fuca Plate Please write out your answers on a separate sheet of paper. In this exercise you are going to be looking at the bathymetry of the Juan de Fuca plate region, identifying interesting features and their characteristics, and attempting to interpret what you see. Some of the questions may be difficult for you to answer now (although hopefully not at the end of the Quarter) – part of the objective is to get you to look carefully at the maps and think rather that immediately writing down an answer. The Instructor and TAs will be coming around the lab answering questions. Figure 1 shows the plate boundaries for the Juan de Fuca plate region and you will use this as your road map as you explore the Juan de Fuca plate with the program GeoMapApp, a versatile program that is used by researchers to look at bathymetry and other seafloor data. To run GeoMapApp do the following 1. Start GeoMapApp on the lab computer from the Start menu or from the Desktop Icon if you have one. If it asks you to install a new version you do not have to. 2. Select the default Mercator Base Map (left hand map) 3. Learn to use the “Zoom In”, “Zoom Out” and “Pan the Map” tools. You can use the “Zoom In” tool either by clicking on the map or holding the mouse button down to rubber-band a box of interest. The Overlays menu allows you to add a Distance Scale and Color Bar.

Earth PhysicsBranch, Pacific GeoscienceCentre, Departmentof Energy, Mines and Resources Sidney,British Columbia Analysis of the magnetic anomalies of the Juan de Fuca plate system allows instantaneouspoles of rotation relative to the Pacific plate to be calculatedfrom 7 Ma to the present.By combiningthese with global solutions for Pacific/America and "absolute" (relative to hot spot) motions, a plate motion sequencecan be constructed.This sequenceshows that both absolute motions and motions relative to America are characterizedby slower velocitieswhere younger and more buoyant material enters the convergencezone: "pivoting subduction."The resistanceprovided by the youngestportion of the Juan de Fuca plate apparently resulted in its detachmentat 4 Ma as the independentExplorer plate. In relation to the hot spot framework, this plate almost immediately began to rotate clockwisearound a pole close to itself such that its translational movement into the mantle virtually ceased.After 4 Ma the remainder of the Juan de Fuca plate adjusted its motion in responseto the fact that the youngest material entering the subductionzone was now to the south. Differencesin seismicityand recent uplift betweennorthern and southernVancouver Island may reflect a distinction in tectonicstyle betweenthe "normal" subductionof the Juan de Fuca plate to the south and a complex "underplating"occurring as the Explorer plate is overriddenby the continent.The history of the Explorer plate may exemplifythe conditionsunder which the self-drivingforces of small subductingplates are overcomeby the influenceof larger, adjacent plates. The recent rapid migration of the absolutepole of rotation of the Juan de Fuca plate toward the plate suggeststhat it, too, may be nearingthis condition.

To aid in distinguishing rhyolite from basaltic lava and help guide sampling and understand spatial distribution, we constructed a classifier using neural networks and fuzzy inference to recognize rhyolite from its lava morphology in sonar data. The Alarcon Rise is ideal to study the relationship between lava flow morphology and composition, because it exhibits a full range of lava compositions in a well‐mapped ocean ridge segment. This study shows that the most dramatic geomorphic threshold in submarine lava separates rhyolitic lava from lower‐silica compositions. Extremely viscous rhyolite erupts as jagged lobes and lava branches in submarine environments. An automated classification of sonar data is a useful first‐order tool to differentiate submarine rhyolite flows from widespread basalts, yielding insights into eruption, emplacement, and architecture of the ocean crust.

Masalu Institute of Marine Sciences, University of Dar es Salaam, P.O. Box 668, Zanzibar, Tanzania ABSTRACT In the past two decades, the mobility of mid-ocean ridges relative to the mantle (absolute migration) has been correlated with major observable features, such as spreading asymmetry and asymmetry in the abundance of seamounts. The mobility of mid-ocean ridges is also thought to be an important factor that influences the diversity of ridge-crest basalts. However, this mobility has not yet been defined and mapped. The absolute migration of global mid-ocean ridges since 85 Ma has been computed and mapped. Global mid-ocean ridges have migrated extensively at varying velocities during that period. Presently, the fast-migrating ridges are the Pacific- Antarctic, Central Indian Ridge, Southeast Indian Ridge, Juan de Fuca, Pacific-Nazca, Antarctic-Nazca, and the Australia-Antarctic ridges, migrating at velocities of between 3.3 and 5.5 cm/yr. The slow-migrating ridges are the Mid-Atlantic and the Southwest Indian ridges, migrating at velocities between 0.3 and 2.0 cm/yr. Comparison of these results with mantle tomography results show that the slow-migrating ridges have deeper depth of origin than the fast-migrating ones, suggesting a correlation between the absolute migration velocity and the depth of origin of ridges.

    The Fate of the Juan de Fuca Plate: Implications for a Yellowstone Plume Head Mei Xue Richard M. Allen Department of Earth and Planetary Science, University of California-Berkeley Submitted to EPSL March 22, 2007 Modified April 4, 2007 Revised Sept 24, 2007 Accepted Sept 29, 2007 Corresponding author: Richard Allen, [email protected], tel 510-642-1275, fax 510- 643-5811, Dept Earth and Planetary Science, University of California Berkeley, 307 McCone Hall, Berkeley, CA 94720-4767, USA 1 Abstract Beneath the Pacific Northwest the Juan de Fuca plate, a remnant of the Farallon plate, continues subducting beneath the North American continent. To the east of the Cascadia subduction zone lies the Yellowstone hotspot track. The origins of this track can be traced back to the voluminous basaltic outpourings in the Columbia Plateau around 17 Ma. If these basalts are the result of a large melting anomaly rising through the mantle to the base of the North America continent, such as a mantle plume head, the anomaly would need to punch through the subducting Juan de Fuca slab. Here, we use teleseismic body wave travel time tomography to investigate the fate of the subducted slab and its possible interaction with a plume head. Our dataset is derived from the Oregon Array for Teleseismic Study (OATS) deployment in Oregon and all other available seismic data in this region. We image the subducted Juan de Fuca plate in the mantle east of the Cascades beneath Oregon, where the slab has not been imaged before, to a depth of 400 km but no deeper.
