Volume 47 of Reviews in Mineralogy and Geochemistry introduces to Noble Gases. Although the mass spectrometry principles are not complex, the tricks involved in getting better data are often self taught or passed on by working with individuals who themselves are pushing the boundaries further. Furthermore, much of the exciting new science is linked with technical developments that allow us to move beyond the current measurement capabilities. Be they better crushing devices, laser resonance time of flight, multiple collection or compressor sources - the technical issues are central to progress.

"Analyses of the noble gases in samples of iron meteorites are presented which indicate the following: 1. The inclusions of iron meteorites contain noble gases with a wide range of isotopic compositions. 2. The noble gas concentration and isotopic anomalies arc often grossly inhomogeneously distributed within a given inclusion and vary from inclusion to inclusion in a meteorite. 3. Silicate inclusions appear to be the most promising samples for I-Xe and Pu-Xe dating. 4. Graphite and troilite in addition to the silicate inclusion contain significant radiogenic 12 9Xe anomalies. 5. The total I-Xe (and in the case of Toluca silicates total Pu-Xe) formation intervals of most of the iron meteorites studied are approximately equal to the total I-Xe and Pu-Xe formation intervals of chondrites. 6. The absence of radiogenic 129Xe in silicate inclusions of the Kodaikanal iron meteorite is consistant with the short Rb-Sr and K-Ar ages of this meteorite. The six points above are interpreted as evidence that iron meteorites were not formed as the molten core of a planetary sized body due to heating and gravitational differentiation of chondritic material. Analyses of stone meteorite data indicate that: 1. The matrix material in addition to the chondrules of stone meteorites are suitable for I-Xe dating. 2. The low temperature data obtained from heating experiments on neutron irradiated meteorites can be used to reconstruct the thermal histories of the stone meteorites. The decay parameters are presented for the following decays: 1. The electron-capture decay of 86Rb. 2. The decay of 134Cs to 134Xe. 3. The double beta-decay of 130Te. 4. The xenon and krypton yields from the spontaneous fission of 252Cf"--Abstract, leaves ii-iii.
