Date:2/22/2013

Boulder, Colo., USA Geology articles posted online ahead of print on 20 Feb. 2013 include several modeling and simulation studies as well as studies on the Exmouth Sub-basin, Australia; the West Kunlun Range, northern Tibetan Plateau; Krakenes Lake, Norway; the Azores islands; and the hot springs of Colorado. The 12 new papers cover a variety of topics:

  1. Taking the easiest pathway to Earth's surface
  2. A challenge to climate change and biotic factors to explain post-glacial lake acidification
  3. Upper-crustal shortening in the Tibetan Plateau
  4. Analysis of diamonds with tiny garnet and silica inclusions -- a gift from ancient ocean floor
  5. Reexamining the Oman ophiolite
  6. Carbon capture and storage problems: CO2 leakage: Natural versus man-made
  7. Modeling the world's largest rivers to understand their diversity
  8. The evolution of colorful insects
  9. Oxygen isotope variability recorded in olivine may be due to recent contamination processes
  10. Hot springs in the Colorado Rockies carry helium and carbon dioxide gases from Earth's mantle, more than 40 km (ten miles) below the surface
  11. Which type of bacteria is responsible for the precipitation of the limestone, the building material of the stromatolites?
  12. Magma ascent, degassing, and active lava domes.
