William Arnuk,


This is the supplemental data associated with the manuscript "Nucleation-assisted microthermometry: a novel application to fluid inclusions in halite" (in prep). Samples measured in this study include lab-grown synthetic halites, Dead Sea varved halites from the 1980s, and Death Valley core DV93-1 halites. Dead Sea and Death Valley halites are further delineated by sampling/depth horizon. Column descriptions/units can be found of the first sheet of the attached .xlsx file; summary statistics and individual sample FI data can be found on the successive four sheets.


Steps to reproduce

Halite crystals were cleaved into thin chips with a single-edge razor blade and then placed on a Linkam THMS600 heating/cooling stage mounted on an Olympus BX52 microscope for visual observation and microthermometric analysis. Single pulses provided by a Clark MXR, Inc. CPA 2101 TI:Sapphire femtosecond laser were used to stimulate vapor bubble nucleation in metastable liquid fluid inclusions. Standard microthermometry protocols were followed to measure observed liquid-vapor homogenization temperatures (Th_obs) (c.f., Goldstein and Reynolds, 1994). Laplace corrections were calculated for different fluid inclusion volumes/brine compositions following Caupin (2022) in order to account for the effects of surface tension on the liquid-vapor interface; Laplace-corrected homogenization temperatures (Th_inf) are presented prior to any hydrostatic pressure corrections, accounting for the pressure of a water column (see main text for details).
