The LHS-1 Lunar Highlands Simulant, developed by Exolith Lab, is a high-fidelity, mineral-based simulant appropriate for a generic or average highlands location on the Moon. The highlands are considered to be the “lighter” regions of the moon’s surface which is mainly comprised of plagioclase, or often referred to as Anothrosite. 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 in accurate proportions referencing the returned Apollo mission regolith.

The simulant is made of several terrestrial minerals, and accurately captures the texture of lunar regolith by combining both mineral and rock fragments (i.e., polymineralic grains) in precise proportions.
The particle size distribution of the simulant is targeted to match that of typical Apollo soils. LHS-1 does not currently simulate agglutinates or nanophase iron. However, our agglutinated simulant, LHS-1-25A, does simulate agglutinates characteristic of an intermediately mature Lunar Highlands Regolith. Custom simulated agglutinate mixes are also available upon request which can be found [here]. [link anorthosite agglutinates]
All of our simulants are an upgraded, high-fidelity alternative to the commonly known JSC-1A simulant.

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.
