Experimental Equipment
Experimental Heating and Cooling Stages
We have a variety of heating and cooling stages including: Linkam TS1500V stage; Linkam TS1400XY; and Linkam THMSG600. The TS1500V and TS1400XY are designed for melt inclusion heating and re-homogenization experiments and can access temperatures of up to 1500 and 1400 °C, respectively. Linkam THMSG600 is specifically designed for micro-thermometry of fluid inclusions with a precision better than 0.1°C and a stability of 0.001°C and temperature range of -195 °C to 600 °C. The experimental heating and cooling stages include Linkam TS96 controllers, vacuum pump, and a modified Olympus BX53MTRF-S long-working distance microscope. Specifically, for the melt inclusion experiments on olivine hosted inclusions we installed a SENTAG oxygen purge system and SENTAG oxygen analyzer to control the state of oxidation of the experiments.

CO2 calibration apparatus for Raman spectroscopy
Our experimental setup at Cornell includes an optical pressure cell is a custom drilled pressure cross rated to 34.47 MPa at 40 ºC, with three high-pressure connections, one medium pressure connection for a thermal probe, and a quartz window drilled into the top. This apparatus is primarily used for CO2 but it can also be used to calibrate the Raman instrument for other gases like CH4, N, etc.

Controlled-atmosphere furnaces
We use two controlled-atmosphere vertical tube Deltech furnaces to equilibrate samples under different partial pressures of O2. Our system is set up for CO-CO2 gas mixing and can reach temperatures of up to 1600 °C. We also use an additional Sentrotech horizontal tube furnace that may be set up to equilibrate samples under vacuum or for ‘soaking’ under inert gases at temperatures up to 1600 °C.

Piston-cylinder apparatuses
Two Rockland Research Corp. piston-cylinders are used to synthesize experiments in ½” and ¾” assemblies at temperatures of up 2000 °C and pressures up to 4 GPa.
