We wanted to let you know about a session that we are organizing for this year's AGU Fall Meeting: "Between a cold outcrop and a hot place: Validation of clumped isotopes and other novel geochemical proxies to shallow crustal geothermometry". Please see the session details below. With this email we are specifically targeting folks within our growing community interested in higher temperature applications of clumped isotopes, and we encourage you all to consider submitting an abstract for a poster or talk. Also, please feel free to forward this email on to others who you think might be interested. Our goal with this session is in part to interact with other proxy communities, so we are hoping to draw interest from a variety of fields (e.g., thermochronology, organic geochemistry, etc).
Abstract submissions opened today and can be found here
. The deadline for submissions is August 6th, 2014
We hope you are having a productive summer and we look forward to seeing you in San Francisco!

Between a cold outcrop and a hot place: Validation of clumped isotopes and other novel geochemical proxies to shallow crustal geothermometry
The reconstruction and interpretation of temperatures in the geological past has historically focused on low-temperature systems (< 50°C) relevant to past climates, or high temperature systems (> 350°C) relevant to metamorphic and igneous processes. Quantitative paleothermometers suitable for intermediate temperatures (50 – 350°C) have been elusive, particularly in settings lacking minerals suitable for fluid inclusions and thermochronology. Temperatures between 50°C and 350°C are relevant to hydrocarbon maturation, mechanics of shallow faulting, genesis of hydrothermal ores, and diagenesis of chemical phases important for paleoclimatic reconstruction.
This session encourages the presentation of innovative techniques and new proxies that may provide quantitative constraints on surface to subsurface processes in the intermediate temperature range (50-350°C), for example, using clumped isotopes, triple oxygen isotopes, non-traditional stable isotopes, fluid inclusions, or organic geochemical proxies.
