LA - LANGUAGE: English AB - ABSTRACT: In the twenty years since terrane mapping was first applied to Mexico, many of the basic boundaries are similar, however the following advances have been made: (i) subdivision of the composite terranes; (ii) delimitation of the terranes in time; (iii) tectonic interpretation of the geological records; (iv) provision of better constraints on the provenance; and (v) reconstruction of actualistic palinspastic maps from the Mesoproterozoic to the present. In the Precambrian and Paleozoic terranes belong either to North America or Middle America (including Maya, Oaxaquia and Honduras), the latter lying adjacent to Amazonia off Venezuela and Colombia. Outboard of Oaxaquia, lay a Cambro-Ordovician, continental rise prism (Petlalcingo Group) and oceanic lithosphere (Acateco Group). The latter was obducted over the former in the Ordovician and/or Silurian and unconformably overlain by the Tecomate overstep sequence to form the Mixteco terrane. The Sierra Madre terrane lay west of Middle America to which it was accreted in the Ordovician (pebbles of the Sierra Madre occur in Wenlockian strata in Oaxaquia). The Coahuiltecano and Tarahumara terranes represent units lying between North and Middle America. All of these terranes were amalgamated into the supercontinent, Pangea, in the Late Permian. Middle Jurassic breakup of Pangea resulted in two continental blocks, Yucatan and Chortis that were surrounded by small ocean basins: Gulf of Mexico, Caribbean Sea, Juarez and Motagua terranes. In western Mexico, the Guerrero composite terrane consists of oceanic arc and periarc complexes, and equivalent terranes, is transitional into continental lithosphere in southern California. Amalgamation of individual terranes into the Guerrero composite terrane in the mid-Cretaceous may have resulted from collision of Baja British Columbia with the trench. An increased convergence rate between the Farallon and North American plates in the Late Cretaceous and early Tertiary resulted in obduction of the Guerrero composite terrane, the Laramide orogeny, inboard migration of the arc, and amalgamation of all the terranes with North America. Neogene propagation of the East Pacific Rise into the North American margin has led to separation of the Baja California block.

LA - LANGUAGE: English AB - ABSTRACT: Volcanic and plutonic rocks of the Cascade arc extend from northern California to British Colombia and preserve a record of subduction-related magmatism over the past approximately 44 Ma. During this interval the arc has experienced variations in several parameters that have the potential to influence magmatism including the rate of subduction, the age and volatile content of the subducting plate, and the stress regime, thickness and composition of the overlying continental crust. This study compares spatial and temporal patterns of magmatic activity in two areas of the Washington Cascades with the goals of: (1) identifying trends that may be related to changing subduction parameters, and (2) contrasting the records of plutonic versus volcanic rocks. The two areas under study are the Chilliwack-Mt. Baker area (CMB), which includes >40 plutons of the Chilliwack batholith (35 Ma to <3 Ma), and the Fifes Peaks-Bumping Lake area (FPBL), which contains over 46 dated volcanic and plutonic units (32 Ma to Recent). In both areas the interval 27-22 Ma was marked by voluminous activity that included emplacement of distinctive leucocratic granitoids indicative of hydrous melting. Both areas then experienced a hiatus ( approximately 22-12 Ma) after which magmatism resumed but was different in character. In the CMB magmatism since 12 Ma is confined to a NE-trending belt within which there is a younger-to-the-SW progression. Plutons in this belt generally have lower Ba/Nb, lower B/Be, higher incompatible element concentrations (e.g., Nb, Th), and smaller areas than the older plutons. These differences may reflect declining fluid flux from the slab (and decreased melting) as the rate of subduction slowed. In the FPBL the hiatus was followed (11-2 Ma) by emplacement of hornblende dacites that have adakite traits (e.g., Sr/Y > 40, Y < 15 ppm) and define a younger-to-the-SE progression. The presence of adakites in the FPBL but not the CMB may reflect a difference between the two areas in the age of the subducting slab. Preliminary results of this study suggest that many of the temporal and spatial trends observed in CMB and FPBL are strongly influenced by local variations in subduction parameters including slab age and geometry.

LA - LANGUAGE: English AB - ABSTRACT: High tech methodologies and theoretical models currently prevail in paleogeographic reconstructions of complex plate boundary areas, but low tech, collections-based paleontological research provides a time frame for tectonostratigraphic events and the geographic connections between marine embayments and plate slivers. Updated nomenclature for Pacific and Caribbean, Holocene and fossil index species and subspecies is critical because the same taxon may have multiple names for living and fossil specimens from different basins. Taxonomic splitting obscures conspecific and phylogenetic relationships that indicate distribution patterns in time and space, and that correlate sediments along the complex Pacific/North American Plate boundary. This area includes the southwestern Basin and Range Province, southern San Andreas Fault system, Gulf Extensional Province, the northern East Pacific Rise and the California Continental Borderland. Tertiary marine fossils from Baja California and the Salton Trough of California have newly refined ages based on associated radiometrically-dated volcanic rocks. They correlate particular embayments in west Mexico and southern California with classic sections in Panama, Costa Rica, Dominican Republic, Trinidad, Venezuela, Colombia and Ecuador. They also relate western Baja California to slivers of tectonic terranes in southern California. Field work and the extensive Paleobiology and Systematic Biology collections in the Smithsonian Institution's National Museum of Natural History provide comparative data on molluscan biodiversity, morphologic variability, geographic distributions and ecology. Work in progress suggests that some taxa are time-transgressive: early Middle to Late Miocene age in west Mexico and the ancient Gulf of California, Miocene, undifferentiated in Panama, Colombia, Venezuela, and Trinidad, and living in the eastern Caribbean. Attention to specific and subspecific nomenclature will greatly improve Bioinformatics databases that aim to include all organisms, living and fossil, world-wide.

Puerto Vallarta, Mexico. April 1-3, 2003. LA - LANGUAGE: English AB - ABSTRACT: U-Pb and 40Ar/39Ar isotopic analyses of various minerals from the lowest structural units of the Acatlan Complex of southern Mexico indicate that low pressure migmatization (5-6 kb), polyphase deformation, and intrusion of felsic and mafic magmas all occurred between 175+ or -3 Ma and 171+ or -1 Ma, i.e. mid-Jurassic. These effects are superimposed upon Ordovician-Silurian and Permian tectonothermal events reflected in older age data in the northern part of the Acatlan Complex. Fractionation of olivine and bronzite in the mafic magmas was associated with assimilation of alumina producing layered lower crustal intrusions of cumulitic dunites, gabbro, and norite that are cut by appinitic dykes. Ensuing rapid cooling through 350 degrees , 280 degrees and 150 degrees C by 167+ or -2 Ma, 166+ or -2 Ma, and 160+ or -14 Ma, respectively, accompanied rapid exhumation (up to 10 km/my), and was followed by deposition of Middle Jurassic (Bajocian=166-160 Ma) sediments. The Jurassic uplift is consistent with the top-to-the west tectonic unroofing inferred to have occurred during the Main phase of deformation. Synchronous tectonic unroofing is also recorded in the adjacent Oaxaca terrane, 100 km to the east, where top-to-the-north, extensional shear zones occur in Paleozoic strata. This pattern of extension suggests radial tectonic unroofing in response to domal uplift (radius >100 km) like that associated with core complexes, slab windows, and hotspots. Most tectonic analyses for the Jurassic place the Acatlan Complex in the forearc region of an arc lying 600-800 km inboard of the subduction zone in Colombia, presumably in response to flat-slab subduction. Modern analogues suggest that flat-slab subduction reflects subduction of young buoyant oceanic lithosphere adjacent to either a mid-oceanic ridge, or a plume. Since core complexes are typical of arc-backarc regions, and slab windows generally produce metamorphic belts, the forearc setting and associated domal uplift suggest a plume to be the most likely cause of this Jurassic tectonothermal pulse in southern Mexico. This plume activity is synchronous with the opening of the Gulf of Mexico during the breakup of Pangea, to which it may have contributed.
