A truck-mounted mass-spectrometer gas analyzer is described and field examples of its use are given. This unit provides a gas analyzer that can be used in the field to rapidly analyze a large number of gases. It has enabled us to establish that gas anomalies occur over a variety of deposit types and in different environments. Gases may prove to be useful geochemical indicators in exploration for concealed mineral deposits. ?? 1990.
