Title: EXPERIMENTAL VAPORIZATION OF THE HOLBROOK CHONDRITE
Abstract: Knudsen cell‐quadrupole mass spectrometry has been used to quantitatively determine the composition of the vapor phase produced by heating samples of the Holbrook chondrite to 1300 °C. Maximum observed vapor pressures (atm) of metals are 10 −5.3 ± 0.3 Na, 10 −5.8 ± 0.3 K, 10 −5.3 ± 0.3 Fe, and 10 −6.6 ± 0.3 Ni at 1200 °C. S 2 (with minor SO 2 ), H 2 O, and CO 2 were also observed in the high‐temperature gas phase. Release of intrinsically derived volatiles produced abundant vesicles in the heated sample residues. Some possible implications for chondrite evolution are briefly discussed
