omposition of altered minerals and to measure the gases given off by the decompositions. After m up, we will collect background data for 30 minutes then begin the ramp. The ramp starts at -60 nd runs to + 1000 C at 20 K/min followed by a 5 minute hold to measure the heat capacity of the n before the ramp returns to low temperatures. We also measure the heat capacity at low perature (where it should be a more sensitive measurement. The procedure also shuts off the nifold heater when the oven and shield are at high temperatures to avoid drawing too much current m the lander. nfiguration: d-temperature ramp has been completed previously.
