Abstract

At the 16th Lunar and Planetary Conference, we reported on a gas-rich fragment of the Allende meteorite. The measurements were done on aliguots from sieve Fractions of a disaggregated fragment of this meteorite, It appeared that the fragment contained only "solar" type inert gases, particularly only so-called Neon-B of the element Ne. We have now done measurements on aliquots of the same materials, but with gas-extractions at 500, 700, 900, 1100, 1300, and 1500 degrees C (in several cases, too little gas was given off to be detected). All inert gases were measured. Also, measurements were done on magnetic as well as non-magnetic separates.
