摘要: Abstract Laser-induced breakdown spectroscopy (LIBS) was used to quantitatively analyze 195 rock slab samples with known bulk chemical compositions, 90 pressed-powder derived from a subset of those rocks, and 31 geostandards under conditions that simulate the ChemCam instrument on Mars Science Laboratory Rover (MSL), Curiosity. The low-volatile ( 20 for some coarse-grained rocks.
