An Integrated Isotopic and Biomarker Analysis of the Glaciogenic Vazante Group, Brazil
(2012)
The Vazante Group, a meta-sedimentary succession located in south-central Brazil, contains several intervals of diamictite, interpreted as glacial in origin, bracketed by well-preserved carbonate and shale. This glacial ...
Geomorphic and Hydrologic Controls on Tidal Prism and Inlet Cross Sectional Area for Chesapeake Bay Lagoons
(2011)
Previous studies have defined a power function between tidal prism and inlet cross sectional area for many lagoon systems. The goals of this study are to first, determine underlying processes that generate the area-prism ...
GLOBAL AND REGIONAL REFERENCE MODELS FOR PREDICTING THE GEONEUTRINO FLUX AT SNO+, SUDBURY, CANADA
(2013)
Determining the radiogenic heat power that is driving plate tectonics and mantle convection is fundamentally important to understanding the Earth's heat budget and its thermal and chemical evolution. The radiogenic heat ...
Reaction rates and textural development of hydrolysis reactions in the system MgO-SiO2-H2O
(2011)
Experiments in the simplified systems MgO-SiO<sub>2</sub>-H<sub>2</sub>O (MSH) and MgO-SiO<sub>2</sub>-H<sub>2</sub>O-CO<sub>2</sub> (MSHC) have been conducted by using hydrothermal diamond anvil cells to investigate ...
MOLYBDENUM ISOTOPE SYSTEMATICS IN NATURAL AND EXPERIMENTAL SETTINGS
(2010)
Molybdenum isotopes have a broad potential applicability for paleoenvironmental analysis, particularly with respect to questions of eutrophication history, development of anoxia, and sedimentation under conditions of ...
STABILITY OF RIDGE-RIDGE-RIDGE TRIPLE JUNCTIONS BASED ON THE MECHANICS OF RIFT INTERACTION: THE NORTHERN GALÁPAGOS AND RODRIGUEZ TRIPLE JUNCTIONS
(2010)
Although known to be kinematically stable, Ridge-Ridge-Ridge (RRR) triple junctions sometimes display a complex sequence of short-lived rifts and no direct connection between the ridges. The Galápagos Triple Junction, in ...
HIGH PRESSURE REDOX GEOCHEMISTRY OF TUNGSTEN IN METAL-SILICATE SYSTEMS: IMPLICATIONS FOR CORE FORMATION IN THE EARTH
(2011)
Geochemical models of core formation are commonly based on core and mantle abundances of siderophile elements. Because of the affinity of these elements for metallic phases, they are thought to be highly concentrated in ...
Metals in Arc Magmas: The Role of Cu-Rich Sulfide Phases
(2011)
Based on experiments performed on hydrous andesitic melts at 1000°C, 150 MPa, <italic>f</italic>O<subscript>2</subscript> from the Co-CoO to Ni-NiO buffer, and log <italic>f</italic>S<subscript>2</subscript> equal to -0.5 ...
Lithium and delta7Li behavior during metamorphic dehydration processes and crustal evolution
(2011)
Li isotopes have been used as a tracer of a wide range of geological processes, because the two stable isotopes of Li have significant relative mass difference and large elemental dispersion in Earth. In order to understand ...
