Teleseismic investigations across the Yellowstone topographic swell reveal: (1) the swell is held up by buoyant mantle of two types—partially molten mantle (of low seismic velocity) beneath the hotspot track and basalt-depleted mantle (of high velocity) beneath the rest of the swell; (2) an upwarped 660 km discontinuity beneath the Yellowstone hotspot track, as expected for relatively hot mantle at that depth, and an upwarped 410 km discontinuity, indicative of relatively cool mantle at this depth; and (3) anisotropic mantle with a preferred northeast orientation of olivine a axis, consistent with the strain expected for both plate motion and hotspot asthenosphere flow. Imaged mantle velocities can be reconciled with a plume hypothesis only if melt buoyancy within the hotspot asthenosphere drives convection, with melt segregating from the mantle beneath Yellowstone and residuum being deposited adjacent to the upwelling. Once such convection is admitted, an alternative, nonplume explanation for Yellowstone is possible, Figure 1. Volcanic-tectonic setting of Yellowstone-Newberry hotspot system.

The ~10 km thickness of the basalt sill therefore implies ~5 km of basalt added to the upper crust across the width of the eastern plain, and the partially molten lower crust suggests an underplating of probably 5 or more km of gabbroic crust. This crustal inflation is not reflected by a greater Moho depth, suggesting that lower crust was squeezed from beneath the eastern Snake River Plain to adjoining regions. Perhaps the most important result of crustal imaging is the information it provides to model crustal density structure, which Figure 2.

Mantle buoyancy holds the swell about 1 km higher than would normal mantle (e.g., eastern U.S. seaboard mantle), whereas mantle southeast of the swell is of more normal density (Peng and Humphreys, 1998).

Yellowstone-Newberry magmatism began vigorously ca. 17 Ma with the eruptions of the central Nevada rift, Steens Mountains, and Columbia River flood basalts (Christiansen and Yeats, 1992). While often attributed to an impact of a plume head, there is no obvious indication of expected uplift preceding initial magmatism. Furthermore, these magmas erupted from a narrow set of fissures extending roughly north-south for ~700 km along the late Precambrian rift margin of North America (Fig. 1). Magmatic activity continued in this vicinity until ca. 12 Ma before propagating (irregularly) northeast toward Yellowstone and west-northwest toward Newberry. With a west-northwest direction of propagation, the Newberry hotspot cannot be connected to a stationary deep-seated plume

TELESEISMIC INVESTIGATION In teleseismic seismology, the distortion of seismic waves is analyzed to infer the structure of the upper mantle and crust through which the waves propagated as they arrive from distant earthquakes to an array of seismometers. To address the structure beneath the Yellowstone swell, we deployed a seismic array occu- pying ~50 sites in a line trending across the width of the swell (Figs. 1 and 3). Our work follows that of Evans (1982), who imaged upper mantle P-wave velocity structure by making use of traveltime delays of the first arriving waves recorded on 1 Hz ver- tical-motion seismometers. Our three-component broadband seismometers enabled receiver function imaging for crust and upper mantle interfaces, S-wave splitting analysis for upper mantle anisotropy, and P- and S-wave tomographic imaging of upper mantle velocity variations—methods now routine in teleseismic seismology.

P-wave velocities (from Sparlin et mantle beneath SRP is anomalously hot beneath SRP at 660 km, but appears al., 1982) suggest that the basalt sill is about half basalt and half to be cool at 410 km.

4 GSA TODAY, December 2000 Yellowstone swell defines a coherent, simple, and distinctive upper mantle anisotropy domain. There are two reasonable ways to interpret the observed upper mantle anisotropy. In the first, buoyant mantle beneath the swell is simply sheared by North America as it moves over a more stable interior (causing the a axis of olivine to align prefer- entially in the direction of plate transport. Another possibility is that a plume supplies buoyant mantle at a high rate, and this buoyant mantle flows to the southwest accommodated by deformation in the previously deposited low-viscosity hotspot asthenosphere (see Fig. 2). In this model, the southwest orientation of the finite elongation direction results from mantle flow driven by the local pressure gradient, and not by passive shear driven by plate motion. The similarity of results from different processes highlights the difficulties in understanding the mecha- nisms responsible for the mantle structure.

Tomographic Imaging of the Upper Mantle Velocity Variations Figure 3 shows an image of the upper mantle P-wave velocity structure (Saltzer and Humphreys, 1997). Red and blue areas represent areas where waves propagate relatively slowly (red) and Figure 4. Schematic of mantle processes active within asthenosphere quickly (blue). The blue areas have a seismic velocity that is about beneath Yellowstone swell. Buoyant and fertile mantle ascends beneath area average for mantle beneath continents. The low-velocity of active hotspot magmatism, possibly supplied by mantle plume (see Fig. 5 for alternative model). Melt buoyancy drives convection in this mantle (large anomaly is about as wide as the Snake River Plain, and is much white arrows). Melt is expelled at top of convective roll (wavy red lines) and narrower than the swell. The prominence of the relatively high- depleted residuum (blue areas) is pushed to sides, where it accumulates. velocity mantle beneath the high-standing swell seems at odds When residuum buoyancy equals melt buoyancy, convective overturn ceases, with simple plume models, which have buoyant mantle dis- leaving partially molten core (red areas). Buoyant mass then flattens (small tributed beneath the entire swell (as in Fig. 2). A nearly universal white arrows) as it is carried southwest by North America plate motion. Effects of hotspot on North America are (1) magmatic modification of Snake relation is that seismically fast rock is dense, yet the mantle is River Plain (SRP) (basaltic underplating of crust, shown in yellow, and intru- highly buoyant across the width of the swell (as discussed in the sion of basalt into midcrust, shown with blue tabular body), which loads and “Receiver Function” section). The only reasonable explanation depresses SRP crust, and (2) uplift of region underlain by buoyant mantle for mantle that is both buoyant and relatively fast is that it is (within the blue envelope), creating Yellowstone swell. With plate motion, significantly depleted in basaltic components. Such depletion Yellowstone encounters increasingly thick lithosphere of Wyoming craton. decreases density while increasing seismic velocity (Jordan, 1979), and this is one of the few cases where density and velocity corre- late inversely. There is only one reasonable explanation for the Dueker and Sheehan (1997) used P-to-S conversions from the 410 km and 660 km seismic discontinuities to assess if locally hot mantle (e.g., plume-affected mantle) deflects these interfaces. Making use of the fact that interface deflection is of opposite sign on these interfaces for a given temperature anomaly (Bina and Helffrich, 1994), the observed thinning of the intervening layer by ~20 km (Fig. 3) beneath the Snake River Plain suggests a thermal anomaly there of 150–200 °C. This result, however, is entirely a consequence of the upwarp in the 660 km discontinuity; the upwarped 410 km discontinuity implies cooler temperatures at this depth beneath the plain.

GeoTrip: Geology of the Grand Canyon—Lee’s Ferry to Pierce and to Ferry. April; 18 participants. Leader: Ivo Lucchitta, U.S. Geological Sur- vey, Flagstaff, Arizona. “Ivo was incredible, very patient with answering my questions. The impact of the trip is still affecting me; I think I’m incredibly lucky to have gone on this trip and I hope I get to do it again!” Argentina in 2000 wrote Shan Stuart, Aspen, Colorado. Photo by David Kirchner. he 2000 GSA GeoVentures Program offered four programs unrelated to the annual or section meetings. The total of 84 participants, ranging in age from 34 to 80, Trepresented a wide range of interests and backgrounds. This educational program serves professionals who enjoy their geology and the company of other geologists in a field setting. GeoVentures are a special benefit created for members, but are open to guests and friends also. GeoVentures is the overall name for adult educational and adventure experiences of two kinds: GeoHostels and GeoTrips. Both are known for superior scientific leadership. Fees are moderate (relative to the destination, length, time of year, and number of participants). GeoHostels are usually five-day, campus- based programs. GeoTrips are anywhere from one to three weeks in length, and the itinerary covers a wide variety of destinations.

GeoHostel: Geology of Southern Utah—Valley of Fire in South- ern Nevada, Zion and Bryce Canyon National Parks of Southern Utah. June; 18 participants. Leaders: Spence Reber, Chevron USA (retired), and Janice Higgins, Dixie College, St. George, Utah. “Leaders were excellent! Spence wrote the book!” said Mel Weidner, Mesa, Arizona.

That would mean finding an additional $130,000/year to augment this program, long a keystone of GSA’s support to students.

GSA TODAY, December 2000 27 Executive Director Division of Hydrologic Sciences The Desert Research Institute (DRI) Las Vegas and Reno, Nevada

DRI, an internationally recognized environmental research institution and a component of the University and Community College System of Nevada (UCCSN), invites applications for the position of Executive Director for our Division of Hydrologic Sciences (DHS). Reporting to the President, the Division Director promotes the needs of DHS faculty; serves as faculty mentor and collaborator; facilitates teaching and research with related departments at UCCSN's two teaching campuses and interacts with current and potential sponsors to further the strategic goals of DHS and the Institute.

The Executive Director we are seeking will bring to DRI a strong scientific background, with proven leadership, communication, administrative, and personnel skills. The Direc- tor will identify and pursue research opportunities relevant to the interests and capabilities of the faculty; represent the research of the faculty to constituencies both within and external to the Institute; develop, in close collaboration with the faculty, a research vision and science plan; work with the Vice President of Academic Affairs to facilitate teaching opportunities for the Division's faculty; and foster interdisciplinary research across the three divisions and two interdisciplinary centers of DRI, with the other campuses of the UCCSN, and other organizations.

With campuses in Las Vegas and Reno, DHS has 50 faculty and support staff, 37 graduate research assistants and hourly employees, and an annual research budget from contracts and grants of ~$6M.
