The LMS-1D Lunar Mare Dust Simulant has been developed by the CLASS Exolith Lab for dust mitigation experiments and other applications where very fine dust is needed. LMS-1D is made of the same base material asLMS-1, our high-fidelity, mineral-based simulant appropriate for a generic or average mare location on the Moon. The simulant is not made of a single terrestrial lithology, but accurately captures the texture of lunar regolith by combining both mineral and rock fragments (i.e., polymineralic grains) in accurate proportions. This dust simulant contains only particles finer than 30 μm.
This table shows the relative abundances of each element detected by X-ray fluorescence (XRF). The relative abundances of elements detected by XRF in geological samples are quantified as oxides. In the simulant, these elements are contained in the minerals described in the Mineralogy table above, and not necessarily in oxide form. These data are from the Hamilton Analytical Lab.
