Abstract
IT has been known since the late nineteenth century that rocks and minerals evolve gas when heated. Early workers1,2 were hampered by the lack of adequate methods for analysing small quantities of gas. They attempted to offset this by using large samples, so that their investigations were mainly restricted to whole rocks3. The use of modern physical methods has made possible the accurate analysis of small amounts of gas4 (< 0.1 cm3 S.T.P.), and a method has been developed for using an A.E.I. MS 10 mass spectrometer to analyse the gas evolved by heated minerals.
