Modeling November 2010 Geology and GSA Today HighlightsGeology includes two papers on the 2009 6.3 L’Aquila earthquake, one of which features a new analysis technique, Focal Mechanism Tomography; a study on the impact of the Three Gorges Dam on the middle Yangtze; three papers on methane hydrates; findings of “easily recognized signatures of life” in iron-oxide-rich spheres and pipes near Escalante, Utah; and examination of a ~300-million-year-old bivalve shell. GSA Today investigates what caused the Dead Interval after the Cambrian explosion.Keywords: methane hydrates, Sri Lanka, monsoons, L’Aquila earthquake, UK North Sea oils, electron paramagnetic resonance spectrometry, Himalayan Range Front, North Anatolian fault, Focal Mechanism Tomography, Navajo sandstone, Gorgona komatiite, Aucanquilcha volcanic cluster, Mount St. Helens, Permian-Triassic marine biotic crisis, Early Permian seasonality, short-wavelength infrared spectroscopy, seawater boron, Akiyoshi karst dolines, Three Gorges Dam, Martian dune gullies, Swatch of No Ground, Cambrian Explosion, Great Ordovician Biodiversification Event.***************Methane recycling between hydrate and critically pressured stratigraphic traps, offshore MauritaniaRichard J.
