  • Introduction San Andreas Fault: an Overview
    Introduction This volume is a general geology field guide to the San Andreas Fault in the San Francisco Bay Area. The first section provides a brief overview of the San Andreas Fault in context to regional California geology, the Bay Area, and earthquake history with emphasis of the section of the fault that ruptured in the Great San Francisco Earthquake of 1906. This first section also contains information useful for discussion and making field observations associated with fault- related landforms, landslides and mass-wasting features, and the plant ecology in the study region. The second section contains field trips and recommended hikes on public lands in the Santa Cruz Mountains, along the San Mateo Coast, and at Point Reyes National Seashore. These trips provide access to the San Andreas Fault and associated faults, and to significant rock exposures and landforms in the vicinity. Note that more stops are provided in each of the sections than might be possible to visit in a day. The extra material is intended to provide optional choices to visit in a region with a wealth of natural resources, and to support discussions and provide information about additional field exploration in the Santa Cruz Mountains region. An early version of the guidebook was used in conjunction with the Pacific SEPM 2004 Fall Field Trip. Selected references provide a more technical and exhaustive overview of the fault system and geology in this field area; for instance, see USGS Professional Paper 1550-E (Wells, 2004). San Andreas Fault: An Overview The catastrophe caused by the 1906 earthquake in the San Francisco region started the study of earthquakes and California geology in earnest.

  • Ontong Java and Kerguelen Plateaux: Cretaceous Icelands?
    Journal of the Geological Society, London, Vol. 152, 1995, pp. 1047-1052, 4 figs. Printed in Northern Ireland Ontong Java and Kerguelen Plateaux: Cretaceous Icelands? M. F. COFFIN & L.M. GAHAGAN Institute for Geophysics, The University of Texas at Austin, 8701 North Mopac Expressway, Austin, Texas 78759-8397, USA Abstract: Together with Iceland, the two giant oceanic plateaux, Ontong Java in the western Pacific and Kerguelen/Broken Ridge in the Indian Ocean, are accumulations of mafic igneous rock which were not formed by 'normal' seafloor spreading. We compare published geochronological, crustal structure, and subsidence results with tectonic fabric highlighted in new satellite-derived free-air gravity data from the three igneous provinces, and conclude that existing evidence weighs lightly against the Ontong Java and Kerguelen plateaux originating at a seafloor spreading centre. Keywords: Iceland, Ontong Java Plateau, Kerguelen Plateau, plumes, hot spots. The two giant oceanic plateaux, Ontong Java in the western Age constraints Pacific, and Kerguelen in the south-central Indian Ocean (Fig. 1), and Iceland are among the best-studied examples of The vast bulk of crust in the ocean basins is dated using large-scale mafic magmatism not resulting solely from magnetic anomalies created by the interplay between the 'normal' seafloor spreading. Analogues on the continents, seafloor spreading process and the alternating polarity of the continental flood basalts, are demonstrably not created by Earth's magnetic field. Mesozoic and Cenozoic marine seafloor spreading, although controversy persists as to magnetic anomalies, summarized globally by Cande et al. whether or not lithospheric extension must precede their (1989), are most commonly tied to geological time through emplacement.

  • Connecting the Deep Earth and the Atmosphere
    In Mantle Convection and Surface Expression (Cottaar, S. et al., eds.) AGU Monograph 2020 (in press) Connecting the Deep Earth and the Atmosphere Trond H. Torsvik1,2, Henrik H. Svensen1, Bernhard Steinberger3,1, Dana L. Royer4, Dougal A. Jerram1,5,6, Morgan T. Jones1 & Mathew Domeier1 1Centre for Earth Evolution and Dynamics (CEED), University of Oslo, 0315 Oslo, Norway; 2School of Geosciences, University of Witwatersrand, Johannesburg 2050, South Africa; 3Helmholtz Centre Potsdam, GFZ, Telegrafenberg, 14473 Potsdam, Germany; 4Department of Earth and Environmental Sciences, Wesleyan University, Middletown, Connecticut 06459, USA; 5DougalEARTH Ltd.1, Solihull, UK; 6Visiting Fellow, Earth, Environmental and Biological Sciences, Queensland University of Technology, Brisbane, Queensland, Australia. Abstract Most hotspots, kimberlites, and large igneous provinces (LIPs) are sourced by plumes that rise from the margins of two large low shear-wave velocity provinces in the lowermost mantle. These thermochemical provinces have likely been quasi-stable for hundreds of millions, perhaps billions of years, and plume heads rise through the mantle in about 30 Myr or less. LIPs provide a direct link between the deep Earth and the atmosphere but environmental consequences depend on both their volumes and the composition of the crustal rocks they are emplaced through. LIP activity can alter the plate tectonic setting by creating and modifying plate boundaries and hence changing the paleogeography and its long-term forcing on climate. Extensive blankets of LIP-lava on the Earth’s surface can also enhance silicate weathering and potentially lead to CO2 drawdown (cooling), but we find no clear relationship between LIPs and post-emplacement variation in atmospheric CO2 proxies on very long (>10 Myrs) time- scales.

  • Turbidites in a Jar
    Activity— Turbidites in a Jar Sand Dikes & Marine Turbidites Paleoseismology is the study of the timing, location, and magnitude of prehistoric earthquakes preserved in the geologic record. Knowledge of the pattern of earthquakes in a region and over long periods of time helps to understand the long- term behavior of faults and seismic zones and is used to forecast the future likelihood of damaging earthquakes. Introduction Note: Glossary is in the activity description Sand dikes are sedimentary dikes consisting of sand that has been squeezed or injected upward into a fissure during Science Standards an earthquake. (NGSS; pg. 287) To figure out the earthquake hazard of an area, scientists need to know how often the largest earthquakes occur. • From Molecules to Organisms—Structures Unfortunately (from a scientific perspective), the time and Processes: MS-LS1-8 between major earthquakes is much longer than the • Motion and Stability—Forces­­ and time period for which we have modern instrumental Interactions: MS-PS2-2 measurements or even historical accounts of earthquakes. • Earth’s Place in the Universe: MS-ESS1-4, Fortunately, scientists have found a sufficiently long record HS-ESS1-5 of past earthquakes that is preserved in the rock and soil • Earth’s Systems: HS-ESS2-1, MS-ESS2-2, beneath our feet.

    January 2016 NEWS COVERAGE PERIOD FROM JANUARY 25TH TO JANURAY 31ST 2016 GOVT BURDENS GAS CONSUMERS WITH RS101BN TO FINANCE PIPELINES Dawn, January 29th, 2016 KHALEEQ KIANI ISLAMABAD: The Economic Coordination Committee (ECC) of the Cabinet on Thursday decided to charge consumers of the two gas utilities Rs101 billion to partly finance pipeline network. At a charged meeting presided over by Finance Minister Ishaq Dar, the committee also approved Rs3 per unit reduction in future power tariff for industrial consumers previously announced by the prime minister in December. It also regularised import of first six cargoes of the liquefied natural gas (LNG) in April-May last year through a floating storage terminal, but deferred a final decision on LNG sales and purchase agreement between Qatargas and Pakistan State Oil (PSO) until Friday. “It was a bad day for member gas (Oil and Gas Regulatory Authority, or Ogra) Amir Naseem,” said a cabinet member who attended the meeting, adding that the finance minister lost his temper at the beginning of the meeting over Ogra’s written comments against petroleum ministry’s summary on Rs101bn financing arrangement for gas companies. Ogra earlier opposed the recovery of Rs101bn from consumers through tariff, saying the pipeline projects should be financed out of Gas Infrastructure Development Cess (GIDC) already being collected from consumers. The regulator believed that it could not allow under the GIDC law the “double taxation” through gas tariff. Consumers, who were already paying GIDC for pipeline infrastructure, could not be burdened again with financing for repayment of Rs101bn loan along with 17 per cent return on assets to be created by the gas companies through these loans.

  • Gondwana Breakup Via Double-Saloon-Door Rifting and Seafloor Spreading in a Backarc Basin During Subduction Rollback
    Available online at www.sciencedirect.com Tectonophysics 445 (2007) 245–272 www.elsevier.com/locate/tecto Gondwana breakup via double-saloon-door rifting and seafloor spreading in a backarc basin during subduction rollback A.K. Martin Repsol YPF Exploración, Al Fattan Plaza, PO Box 35700, Dubai, United Arab Emirates Received 2 February 2007; received in revised form 4 July 2007; accepted 21 August 2007 Available online 28 August 2007 Abstract A model has been developed where two arc-parallel rifts propagate in opposite directions from an initial central location during backarc seafloor spreading and subduction rollback. The resultant geometry causes pairs of terranes to simultaneously rotate clockwise and counterclockwise like the motion of double-saloon-doors about their hinges. As movement proceeds and the two terranes rotate, a gap begins to extend between them, where a third rift initiates and propagates in the opposite direction to subduction rollback. Observations from the Oligocene to Recent Western Mediterranean, the Miocene to Recent Carpathians, the Miocene to Recent Aegean and the Oligocene to Recent Caribbean point to a two-stage process. Initially, pairs of terranes comprising a pre-existing retro-arc fold thrust belt and magmatic arc rotate about poles and accrete to adjacent continents. Terrane docking reduces the width of the subduction zone, leading to a second phase during which subduction to strike-slip transitions initiate. The clockwise rotated terrane is caught up in a dextral strike-slip zone, whereas the counterclockwise rotated terrane is entrained in a sinistral strike-slip fault system. The likely driving force is a pair of rotational torques caused by slab sinking and rollback of a curved subduction hingeline.

  • JOIDES Resolution Expedition 361 (Southern African Climates) Site
    IODP Expedition 361: Southern African Climates Site U1475 Summary Background and Objectives Site U1475 is located on the southwestern flank of Agulhas Plateau (41°25.61′S, 25°15.64′E), ~450 nmi south of Port Elizabeth, South Africa, in a water depth of 2669 mbsl. The Agulhas Plateau, which was formed during the early stages of the opening of the South Atlantic about 90 Ma (Parsiegla et al., 2008), is a major bathymetric high that is variably coated with sediments (Uenzelmann Neben, 2001). The 230,000 km2 plateau, which ascends up to ~2500 m above the adjacent seafloor, is bounded on the north by the 4700 m deep Agulhas Passage and is flanked by the Agulhas Basin in the west and the Transkei Basin in the northeast. The northern part of the plateau is characterized by rugged topography, while the central and southern part of the plateau exhibits a relatively smooth topography (Allen and Tucholke, 1981) and has greater sediment thickness (Uenzelmann Neben, 2001). A strong water mass transport flows across the Agulhas Plateau region (Macdonald, 1993), which involves the water column from the surface down to Upper Circumpolar Deep Water. The hydrography of the upper ocean is dominated by the Agulhas Return Current, which comprises the component of the Agulhas Current that is not leaked to the South Atlantic Ocean but rather flows eastwards from the retroflection (Lutjeharms and Ansorge, 2001). Antarctic Intermediate Water, below the Agulhas Return Current, also follows the same flow path near South Africa as the Agulhas Current showing a similar retroflection (Lutjeharms, 1996).

  • The Shatsky Rise Oceanic Plateau Structure from Two-Dimensional Multichannel Seismic Refl Ection Profi Les and Implications for Oceanic Plateau Formation
    Downloaded from specialpapers.gsapubs.org on June 2, 2015 The Geological Society of America Special Paper 511 2015 The Shatsky Rise oceanic plateau structure from two-dimensional multichannel seismic refl ection profi les and implications for oceanic plateau formation Jinchang Zhang* William W. Sager† Department of Oceanography, Texas A&M University, College Station, Texas 77843, USA Jun Korenaga Department of Geology and Geophysics, Yale University, New Haven, Connecticut 06520, USA ABSTRACT The Shatsky Rise is one of the largest oceanic plateaus, a class of volcanic fea- tures whose formation is poorly understood. It is also a plateau that was formed near spreading ridges, but the connection between the two features is unclear. The geologic structure of the Shatsky Rise can help us understand its formation. Deeply penetrating two-dimensional (2-D) multichannel seismic (MCS) refl ection profi les were acquired over the southern half of the Shatsky Rise, and these data allow us to image its upper crustal structure with unprecedented detail. Synthetic seismo- grams constructed from core and log data from scientifi c drilling sites crossed by the MCS lines establish the seismic response to the geology. High-amplitude basement refl ections result from the transition between sediment and underlying igneous rock. Intrabasement refl ections are caused by alternations of lava fl ow packages with dif- fering properties and by thick interfl ow sediment layers. MCS profi les show that two of the volcanic massifs within the Shatsky Rise are immense central volcanoes. The Tamu Massif, the largest (~450 km × 650 km) and oldest (ca. 145 Ma) volcano, is a single central volcano with a rounded shape and shallow fl ank slopes (<0.5°–1.5°), characterized by lava fl ows emanating from the volcano center and extending hun- dreds of kilometers down smooth, shallow fl anks to the surrounding seafl oor.
