Jay Quade

About

Professor Jay Quade's research is quite broad but centers on low-temperature geochemistry, radiometric dating, and paleoenvironmental reconstruction, primarily focused on the Cenozoic era. He and his students have conducted research across various regions including the western USA, central Asia, Ethiopia, southern South America, and Turkey. His work often involves collaboration with archaeologists and anthropologists on recent projects. The analytical work for his research is primarily carried out in the Environmental Isotope Laboratory run by Dave Dettman and the Accelerator Mass Spectrometry facility led by Greg Hodgins, specializing in 14 C dating. Professor Quade has taught a range of courses related to geochemistry, isotopic methods, and the coevolution of the Earth and biosphere, and he actively shares datasets and research compilations. His office is located in the Gould-Simpson Building at the University of Arizona, and he maintains contact through email and phone.

• The role of the westerlies and orography in Asian hydroclimate since the late Oligocene

  Geology · 2020 · 83 citations

  Abstract Interactions between midlatitude westerlies and the Pamir–Tian Shan mountains significantly impact hydroclimate patterns in Central Asia today, and they played an important role in driving Asian aridification during the Cenozoic. We show that distinct west-east hydroclimate differences were established over Central Asia during the late Oligocene (ca. 25 Ma), as recorded by stable oxygen isotopic values of soil carbonates. Our climate simulations show that these differences are present w…

• Rapid and precise measurement of carbonate clumped isotopes using laser spectroscopy

  Science Advances · 2022 · 28 citations

  produced by digestion of 51 synthetic carbonates equilibrated at 6° to 1100°C is consistent with results for natural carbonates and previous calibrations. Our system results were indistinguishable from IRMS systems after replicating the InterCarb interlaboratory calibration. Measurement by TILDAS could change the landscape for clumped isotope analysis.
