Test record WITHOUT Related uRLs: X-ray Diffraction Results from Mars Science Laboratory: Mineralogy of Rocknest at Gale Crater

TL;DR: The Curiosity rover Curiosity scooped samples of soil from the Rocknest aeolian bedform in Gale crater and analyzed the soil with the Chemistry and Mineralogy (CheMin) x-ray diffraction (XRD) instrument revealed plagioclase, forsteritic olivine, augite, and pigeonite, with minor K-feldspar, magnetite, quartz, anhydrite, hematite and ilmenite.

Mineralogy and geochemistry of sedimentary rocks and eolian sediments in Gale crater, Mars: A review after six Earth years of exploration with Curiosity

Elizabeth B. Rampe, +76 more
TL;DR: The Curiosity rover was sent to Gale crater to study a sequence of ∼3.5 Ga old sedimentary rocks that, based on orbital visible and near-to short-wave infrared reflectance spectra, contain secondary minerals that suggest deposition and/or alteration in liquid water.

Evolved Gas Analyses of Sedimentary Rocks and Eolian Sediment in Gale Crater, Mars: Results of the Curiosity Rover's Sample Analysis at Mars Instrument.

TL;DR: The Sample Analysis at Mars instrument evolved gas analyzer (SAM-EGA) has detected evolved water, SO2, NO, CO2, CO, O2, and HCl from two eolian sediments and nine sedimentary rocks from Gale Crater, Mars as mentioned in this paper.

Early Proterozoic climates and plate motions inferred from major element chemistry of lutites

TL;DR: The early Proterozoic Huronian Supergroup of the north shore of Lake Huron (Fig. 1) is a thick succession of sedimentary and volcanic rocks deposited between about 2,500 and 2,100 Myr ago as discussed by the authors.

Mobility and fractionation of rare earth elements during weathering of a granodiorite

TL;DR: The rare earth elements (REE) have been mobilised and fractionated during supracrustal alteration of the Torrongo granodiorite as mentioned in this paper, and the residual products are especially depleted in the heavy REE.

Deposition, exhumation, and paleoclimate of an ancient lake deposit, Gale crater, Mars.

TL;DR: The observations suggest that individual lakes were stable on the ancient surface of Mars for 100 to 10,000 years, a minimum duration when each lake was stable both thermally (as liquid water) and in terms of mass balance (with inputs effectively matching evaporation and loss of water to colder regions).

The ChemCam Instrument Suite on the Mars Science Laboratory (MSL) Rover: Body Unit and Combined System Tests

Roger C. Wiens, +97 more
TL;DR: The first laser-induced breakdown spectrometer (LIBS) was used on the Mars Science Laboratory (MSL) rover Curiosity for remote compositional information using the first LIBS on a planetary mission, and provided sample texture and morphology data using a remote micro-imager.
