  Controls on the Termination of Cretaceous Oceanic Anoxic Event 2 in the Tarfaya Basin, Morocco
  Chiara KrewerSimon W. PoultonRobert J. NewtonChristian MärzBenjamin J. W. MillsThomas Wagner

  The recovery from OAE2 in the Tarfaya Basin was driven by decreasing chemical weathering, less intensely reducing conditions and pulses of phosphorous drawdown.

  Quantifying Closed-Basin Lake Temperature and Hydrology by Inversion of Oxygen Isotope and Trace Element Paleoclimate Records
  Daniel E. IbarraC. Page Chamberlain

  Lake systems are important paleoclimate archives that preserve ecosystem and hydrologic responses to critical periods in Earth history, such as carbon cycle perturbations and glacial-interglacial cycles. Geochemical measurements of biogenic...

  Paleoredox and Pyritization of Soft-Bodied Fossils in the Ordovician Frankfort Shale of New York
  Úna C. FarrellDerek E. G. BriggsEmma U. HammarlundErik A. SperlingRobert R. Gaines

  Multiple beds in the Frankfort Shale (Upper Ordovician, New York State), including the original “Beecher9s Trilobite Bed,” yield fossils with pyritized soft-tissues. A bed-by-bed geochemical and sedimentological analysis was carried...

  Elemental Release Rates From Dissolving Basalt and Granite With and Without Organic Ligands
  E. M. HausrathA. NeamanS. L. Brantley

  Bacteria, fungi, lichen and plants all produce organic acids, which can strongly affect weathering by increasing the solubility and mobility of elements. Leaching by organic acids may therefore produce trace...
