Seven types of basalt mare have grain density from 3270 ± 10 to 3460 ± 50 kg/m 3 . These lunar basalts are denser than terrestrial basalts, which reflects the much more abundant FeO in lunar basalts. For a typical moon horse porosity of ~7% (range 2-10%), the bulk density (relevant parameter for gravity models) ranges from 3010 ± 40 to 3270 ± 50 kg / m 3 .
Four types of feldspar plateau rocks with grain density from 2840 ± 10 to 2910 ± 10 kg/m 3 with porosity from 2-11%; bulk density from 2510 ± 20 to 2840 ± 40 kg/m 3 .
The particle density of the two impact holes is 3030 ± 30 and 3050 ± 10 kg/m 3. Porosity ranges from 17-22%. Density from 2360 ± 40 to 2520 ± 30 kg/m 3 .
