Abstract: Abstract Carbonate clumped isotope (Δ 47 ) thermometry has been applied to a wide range of problems in earth, ocean and biological sciences over the last decade, but is still plagued by discrepancies among empirical… read more here.

Abstract: The measurement of multiply isotopically substituted (‘clumped isotope’) carbonate groups provides a way to reconstruct past mineral formation temperatures. However, dissolution-reprecipitation (i.e., recrystallization) reactions, which commonly occur during sedimentary burial, can alter a sample’s clumped-isotope… read more here.

Abstract: The Mormon Peak and Heart Mountain detachments are carbonate-‐hosted low-‐angle faults of Tertiary age in the western United States that formed in the uppermost continental crust. Both faults were active during regional explosive volcanism, with… read more here.

Abstract: Carbonate clumped isotope abundance is an important paleothermometer, but measurement is difficult, slow, and subject to cardinal mass (m/z) interferences using isotope ratio mass spectrometry (IRMS). Here, we describe an optical spectroscopic measurement of carbonate… read more here.
