The geochemistry of multiply substituted isotopologues ('clumped-isotope' geochemistry) examines the abundances in natural materials molecules, formula units or moieties that contain more than one rare isotope (e.g. (13)C(18)O(16)O, (18)O(18)O, (15)N(2), (13)C(18)O(16)O(2) (2-)). Such species form basis carbonate clumped-isotope thermometry and undergo distinctive fractionations during a variety processes, but initial reports have provided few details their analysis. In this study, we...
Abstract Increased use and improved methodology of carbonate clumped isotope thermometry has greatly enhanced our ability to interrogate a suite Earth‐system processes. However, interlaboratory discrepancies in quantifying (Δ 47 ) measurements persist, their specific sources remain unclear. To address differences, we first provide consensus values from the community for four standards relative heated equilibrated gases with 1,819 individual analyses 10 laboratories. Then analyzed along three...
Abstract The potential for carbonate clumped isotope thermometry to independently constrain both the formation temperature of minerals and fluid oxygen composition allows insight into long‐standing questions in Earth sciences, but remaining discrepancies between calibration schemes hamper interpretation measurements. To address calibrations, we designed analyzed a sample suite (41 total samples) with broad applicability across geosciences, an exceptionally wide range temperatures,...

The elevation history of Earth's surface is key to understanding the geodynamic processes responsible for rise plateaus. We investigate timing Colorado Plateau uplift by estimating depositional temperatures Tertiary lake sediments that blanket plateau interior and adjacent lowlands using carbonate clumped isotope paleothermometry (a measure temperature‐dependent enrichment 13 C‐ 18 O bonds in carbonates). Comparison modern ancient samples deposited near sea level provides an opportunity...
Rationale The clumped isotope composition of CO 2 (Δ 47 ) derived from carbonate is widely used as a paleotemperature proxy with broad applications in geoscience. Its accuracy is, however, limited by inter‐laboratory discrepancies reference materials and disagreement among geothermometer calibrations. Here we show how the correction for abundance 17 O influences these discrepancies. Methods We ‐H equilibration at known temperatures phosphoric acid digested carbonates to generate samples wide...
We describe an approach to estimating the crystallization temperatures of diagenetic calcites using clumped-isotope thermometry, a paleothermometer based on 13 C-18 O-bond enrichment in carbonates.Application this thermometer calcified gastropod shells and calcite cements early Eocene limestone from Colorado Plateau reveals record precipitation replacement at varying 14 123uC.The host sediments were never deeply buried, but they experienced significant thermal pulse associated with...

Carbonate minerals contain stable isotopes of carbon and oxygen with different masses whose abundances bond arrangement are governed by thermodynamics. The clumped isotopic value Δi is a measure the temperature-dependent preference heavy C O to clump, or near each other, rather than light in carbonate phase. isotope thermometry uses values measured mass spectrometry (Δ47, Δ48) laser spectroscopy (Δ638) reconstruct mineral growth temperature surface subsurface environments independent parent...
In the Himalaya and other active convergent orogens, linear relationships between thermochronometer sample age elevation are often used to estimate long‐term exhumation rates. these regions, high‐relief topography nonvertical pathways may invalidate such one‐dimensional (1‐D) interpretations lead significant errors. To quantify errors, we integrate apatite fission track (AFT) ages from central with a 3‐D coupled thermokinematic model, which cooling predicted using cooling‐rate‐dependent...
The Himalayan syntaxes are exceptionally dynamic landscapes characterized by high-relief topography and some of the most rapid focused crustal exhumation on Earth. In eastern syntaxis, it has been hypothesized that thermo-mechanical feedbacks between erosion Yarlung River growth a crustal-scale antiform may have locally sustained rates exceeding 5 km/m.y. during late Pliocene Pleistocene. However, young (younger than 3 Ma) cooling histories from syntaxial bedrock samples restrict...

Abstract Syndepositional faults and fractures are known to affect early fluid flow in carbonate platforms. Less clear is whether they active conduits throughout the entire history of platform strata. Syndeformational Permian (late Guadalupian) carbonates exposed Dark Canyon, Guadalupe Mountains, New Mexico, U.S.A., address this question. Transmitted-light cathodoluminescent petrography, stable-isotope fluid-inclusion analyses, clumped-isotope thermometry show that there were multiple...
