Glass: A source of data leading to constraints on the volcanic, impact, and atmospheric histories of MarsVolcanism and impact are important processes on Mars. Both mechanisms can produce glasses. Criteria exist for distinguishing between impact glasses and volcanic glasses. Owing to the single-phase nature of glass, tiny pieces (approximately 50-micrometer diameter) are as compositionally representative as larger pieces, in contrast to multi-phase crystalline samples, such as basalts. The thesis of this abstract is that glasses may be common in the Martian regolith and should be a high-priority sample owing to their combination of: (1) low representative mass, and (2) high content of information.
