摘要
Two recent Icarus papers on the geology of Mars' Elysium plain (Diez et al. 2009 [Icarus 200, 19-29] and Jaeger et al. 2010 [Icarus 205, 230-243]) raise the issue of what gamma ray, neutron, and visible-infrared spectral observations (GRS-NS, CRISM1) mean geologically. This question is important because spectrometric data are readily accepted as supporting evidence of a particular geology (e.g., flood-volcanism on Mars). However, chemical composition is not a proxy for lithology. (C) 2010 Published by Elsevier Ltd.
