  Clumped Isotope Constraints on Warming and Precipitation Seasonality in Mongolia Following Altai Uplift
  Jeremy K. Caves RugensteinKatharina MethnerTyler KuklaAndreas MulchTina LüdeckeJens FiebigAnne MeltzerKarl W. WegmannPeter ZeitlerC. Page Chamberlain

  The timing of surface uplift of the Altai Mountains in northern Central Asia—and the climatic consequences—remains controversial. Today, the Altai Mountains cast a substantial rain shadow, effectively separating the western...

  Rock Weathering and Nutrient Cycling Along an Erodosequence
  Friedhelm von BlanckenburgJan A. SchuesslerJulien BouchezPatrick J. FringsDavid UhligMarcus OelzeDaniel A. FrickTilak HewawasamJeannie DixonKevin Norton

  How flowing water and organisms can shape Earth9s surface, the Critical Zone, depends on how fast this layer is turned over by erosion. To quantify the dependence of rock weathering...

  The Role of Vegetation in Setting Strontium Stable Isotope Ratios in the Critical Zone
  Julien BouchezFriedhelm von Blanckenburg

  At Earth9s surface the stable isotope ratio of strontium (88Sr/86Sr) is predominantly set by biological uptake of Sr and its storage in plant litter. This conclusion was reached from a...

  Paleoaltimetry of the Western Andes in Northern Chile (∼18.5–19.5°S)
  Sebastian Jimenez-RodriguezMatthew DettingerJay QuadeKendra E. Murray

  Establishing the timing of surface uplift in the Central Andes is essential for evaluating the geodynamic mechanisms responsible for mountain building and their role in the development of dry conditions...

  Isotope Hydrology of Early Paleogene Lake Flagstaff, Central Utah: Implications for Cordilleran Evolution
  Justin H. VanDeVeldeGabriel J. Bowen

  Lacustrine sediments from Paleogene foreland basins of the North American Cordillera serve as powerful integrators of information on climatic and tectonic conditions, but episodes of hydrologic connection between basins may...

  Aridification of Central Asia and Uplift of the Altai and Hangay Mountains, Mongolia: Stable Isotope Evidence
  Jeremy K. CavesDerek J. SjostromHari T. MixMatthew J. WinnickC. Page Chamberlain

  Central Asia has become increasingly arid during the Cenozoic, though the mechanisms behind this aridification remain unresolved. Much attention has focused on the influence and uplift history of the Tibetan...

  Modeling Novel Stable Isotope Ratios in the Weathering Zone
  Julien BouchezFriedhelm von BlanckenburgJan A. Schuessler

  When rock is converted to weathering products, the involved processes can be fingerprinted using the stable isotope ratios of metals (for example Li, Mg, Ca, Fe, Sr) and metalloids (B,...

  Country Rock Monazite Response to Intrusion of the Searchlight Pluton, Southern Nevada
  John C. AyersScott CrombieMiranda LoflinCalvin F. MillerYan Luo

  We investigated how monazite grains in country rocks responded to the intrusion of the Miocene Searchlight pluton in southern Nevada. Country rock samples were collected from the roof zone and...

  Controls on the Spatial Variability of Modern Meteoric δ¹⁸O: Empirical Constraints From the Western U.S. and East Asia and Implications for Stable Isotope Studies
  Alex R. LechlerNathan A. Niemi

  We analyze a dataset of multiannual modern precipitation and meteoric water records from the western U.S. (n = 206) and east Asia (n = 478) to (1) determine which environmental...

  Fluid-rock Interaction During Formation of Metamorphic Quartz Veins: A REE and Stable Isotope Study From the Rhenish Massif, Germany
  Thomas WagnerAdrian J. BoyceJörg Erzinger

  We have investigated fluid-rock interaction processes during formation of metamorphic quartz veins that are abundant in the fold-and-thrust belt of the Rhenish Massif, southwest Germany. These veins record two successive...
