The LMS-1 Lunar Mare Simulant has been developed by the CLASS Exolith Lab. It is a 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.

The particle size distribution of the simulant is targeted to match that of typical Apollo soils. LMS-1 does not currently simulate agglutinates or nanophase iron.

Bulk Chemistry

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.
