The authors have developed an integrated remote Raman and laser-induced breakdown spectroscopy (LIBS) system for measuring both the Raman and LIBS spectra of minerals with a single 532 nm laser line of 35 mJ/pulse and 20 Hz. The instrument has been u

Dhofar 019 is a new martian meteorite found in the desert of Oman. In texture, mineralogy, and major and trace element chemistry, this meteorite is classified as a basaltic shergottite. Olivine megacrysts are set within a groundmass composed of finer

There is abundant geomorphic evidence that Mars once had potentially significant amounts of water on its surface. Bulk martian meteorites are curiously dry, and hydrated minerals found in some of these rocks are also surprisingly low in water content

— We present the results of a combined mineralogic-petrologic and ion microprobe study of two martian meteorites recently recovered in the Lybian Sahara, Dar al Gani 476 (DaG 476) and Dar al Gani 489 (DaG 489). Having resided in a hot desert enviro

[1] The terrestrial geologist's hand lens is a fundamental tool for identifying and correlating rocks and minerals. We used rover-inspired methods of remote hand lens–scale data acquisition to conduct reconnaissance of a well-characterized Martian

We have developed a remote Raman system, using an 8-in telescope and a 532-nm pulse laser (20 Hz and 20 mJ/pulse), which is capable of operating in daylight. From distances of 50 and 100 m and with an integration time of just 1 second (equivalent to

Observations of martian surface morphology have been used to argue that an ancient ocean once existed on Mars1. It has been thought that significant quantities of such water could have been supplied to the martian surface through volcanic outgassing,
