ABSTRACT Continuously recorded Global Posi- tioning System (GPS) data from the northern Basin and Range suggest that contemporary deformation is quite slow and broadly distributed, rather than being concentrated in the relatively nar- row zones of historical earthquakes. Sur- prisingly, however, in north-central Nevada, the data indicate rapid, range- normal crustal shortening at a rate of 2–3 mm/yr in an area where the geology indicates crustal extension via Holocene normal faulting. A possible explanation for the conflicting geodetic and geologic data is that the region of shortening represents the contractile side of a slowly east-propagating deformation pulse generated by the 1915 Pleasant Valley and 1954 Dixie Valley and Fairview Peak earthquakes. Such pulses, which are transient effects not recorded by faulting, are predicted by a broad class of physical models, but have only been observed within a few years after very large earthquakes, when the signal is much larger than the long-term deformation rate. The Basin and Range, and similar areas with a combination of low long-term deformation rates and large earthquakes, may therefore have Figure 1.

4 GSA TODAY, November 2000 interpretations is illustrated by comparison of the west components of velocity for the two network solutions (Fig. 2C). Thus, evaluating error sources in both continuous and campaign modes of surveying is crucial to resolving the apparent dif- ference. For our ~2.5 yr solution, formal errors (1 σ) in site velocity (either between sites or relative to a North American reference frame) are in the 0.1–0.2 mm/yr range (Davis et al., 1999). The formal errors, which account for uncertainties in phase measurement, timing (clock error), satellite position, atmospheric distortion, and other effects, may underestimate the true uncertainty or accuracy of the solution, which could arise from factors such as monument instability. The formal errors are reasonable estimates, however, because the scatter of the west velocities about a regression line is only about 0.5 mm/yr. If the actual errors were significantly higher, then the scatter of the data would be significantly greater than this value (Davis et al., 1999). This value is therefore an upper bound, because a significant component of the scatter may of course be due to real variations from linearity in the deformation field, rather than error. For the 11 sites in the eastern part of the network where north velocities are near zero, the scatter about a line of zero slope is only ~0.3 mm/yr (Fig. 2B; Davis et al., 1999). Assuming a model of no differential north- south motion for the eastern part of the network (a reasonable inference based on the geology), this value is near the formal error in velocity. In sum, we estimate our velocity error at 0.5 mm/yr based on 2.0–2.5 years of data, noting there is a reasonable possibility that errors may be as low as 0.1–0.2 mm/yr (Davis Figure 4. Time series of west positions between selected sites in BARGEN et al., 1999). In contrast, a campaign-mode effort in the same network.

Using these networks, inferred velocities were accurate to within 1–2 mm/yr, with gradual improvement only possible after decades of repeated surveys. As illustrated below, GPS geodetic solutions using continuously acquired data yield directly the velocity of each site in a global reference frame (i.e., velocity fields), accurate to within as little as ±0.2–0.5 mm/yr, and large- scale strain rates to within ±2 nstr/yr, in just a few years of monitoring. The method is comparatively inexpensive because sites need not be on mountain peaks, require little visitation once installed, and yield results in years rather than decades. Obvi- ously, this new capability opens a vast horizon for observing fault systems, especially at scales larger than a few tens of kilometers and strain rates of 10 nstr/yr or less, as required for study of most intraplate fault systems and strain transients. The velocity field, relative to the North American plate, of the first 18 BARGEN sites installed (in 1996 and 1997), shows monotonically increasing west to northwest velocity, from near 0 mm/yr on the east side of the province up to 12 mm/yr on the west, becoming more northerly from east to west (Fig. 2A; see http://cfa-www.harvard.edu/space_geodesy/BARGEN [September 2000] for a data table). The west components of motion increase monotonically westward, indicating broadly distributed extensional strain at a rate of ~10 nstr/yr. By comparison, rates adjacent to the San Andreas fault system are as much as 200–300 nstr/yr (e.g., Bennett et al., 1999), or 20–30 times Basin and Range rates. The north components of velocity are near zero across the eastern half of the province, but from central Nevada to the Sierra Nevada increase rapidly westward to values near 7 mm/yr. One site in the network (LEWI, Fig. 2A), however, lies well off these trends in both north and west components, raising the question of relatively large systematic error in continuous GPS Figure 5.

Great Basin and Sierra Nevada: GSA Field Guide 2 Edited by David R. Lageson, Stephen G. Peters, and Mary M. Lahren

This second volume of the GSA Field Guide Series is a comprehensive compilation of new and exciting research on this amazingly diverse region, with well-crafted guides to field localities of special interest. Full-color plates in some chapters make this guide an especially appealing and useful volume. The volume gives complete coverage of field trips held in conjunction with the 2000 GSA Annual Meeting in Reno. Chapters cover the active tectonics of Lake Tahoe and the historical surface faulting and paleoseis- micity of the central Nevada seismic belt, the Neoproterozoic glacial record of Death Valley, Meso- zoic plutonism in the Sierra Nevada, Paleozoic subduction, Ordovician stratigraphy, and much more. The geology of the Nevada Test Site and of the nuclear-waste repository at Yucca Mountain also is discussed. Also included is an invited field guide from the 1999 GSA Cordilleran Section meeting that covers the wines and geology of Napa Valley, California.

In addition, he has worked extensively on the mineralogy of low-grade rocks near Wellington and on the higher-grade rocks exposed along the Alpine fault. He also has an extensive knowledge of New Zealand history and prehistory, and he invariably includes background information and stories that relate to the areas visited. Description The accompanying photo embodies this GeoVenture: amazing geology, stun- ning scenery, and classic accommodations. During our journey, we will visit the three primary types of plate boundaries, witness the landforms they produce, travel from subtropical to alpine ecozones, and discuss how Earth and life systems interact in such complex settings. Included will be several boat excursions, helicopter flights, and stays in some of the world’s most spectacular accommodations. Leg one of our six-leg journey begins in Auckland and takes us to the Bay of Islands. We will introduce Maori mythology and discuss the Treaty of Waitangi and the New Zealand wars (three days). Leg two focuses on the active volcanoes in Tongariro National Park, where we visit the Taupo Volcanic Zone, the Grand Chateau on Mount Ruapehu, and the Wairakei Geothermal Power Station (four days). Leg three heads south toward Welling- ton where we discuss Sir Charles Lyell, the 1855 magnitude 8+ Wairarapa earthquake, Red Rocks on the South Coast, and the National Museum (three days).

GSA TODAY, November 2000 31 Tectonic Evolution of South America Edited by U.G. Cordani, E.J. Milani, A. Thomaz Filho, and D.A. Campos In partnership with the 31st International Geological Congress Organizing Committee, and with support from the Departmento Nacional de Pro- ducão Mineral and the Academia Brasileira de Ciências, GSA is distribut- ing this comprehensive volume that summarizes the evolution of the tectonostratigraphic terrains of the South American continent. It is the first compilation of South American geology since 1953 and the first synthesis written since the advent of global plate tectonics. Published to coincide with the 31st Interna- tional Geological Congress held in Rio de Janeiro, Brazil, in August 2000, the volume pre- sents the work of more than 70 authors in 25 regionally focused articles. The volume’s first two sections are dedicated to the tectonic evolution of the South American continent in the Precambrian. The first covers the older cratonic units, and the second is related to the

Sections three and four are concerned with the Phanerozoic geologic history. The former deals with the extra-Andean region and includes a chapter on the large cratonic sedimentary basins of the continent. The latter’s series of chapters Toll-free: 888-443-4472 describe the tectonic evolution of the Andean belt, which forms the backbone of South America. The final section Fax: 303-443-1510 of the volume summarizes the mineral and fossil fuel resources of South America, including a complete review of www.geosociety.org the continental basins and their associated petroleum megasystems; a review of the stratigraphy and resource estimates for the continent’s coal deposits; a review of the Andean metallic ore deposits which represent more GSA Publication Sales than 25% of the world’s copper and more than a third of the world’s molybdenum; and an overview of the Precam- P.O.
