Basalt
origin | sample collected at Tenerife Island (Canary archipelago, Spain), which corresponds to the 1705 Arenas Negras volcanic eruption |
main constituent | pyroxene (augite), plagioclase and olivine |
practical significance | basalt is an extrusive igneous commonly found in volcanic environment on Earth and probably on different Solar System bodies such as Mars, where it can constitute an important fraction of atmospheric and surface dust |
particle size | measured size distributions Mie: reff=6.9 μm, v Fraunhofer: reff=2.9 μm, veff=15.1 |
particle shape | irregular |
refractive index | 1.52 + i0.00092 (488nm)
1.52 + i0.001 (647nm) (Pollack et al. 1973) |
color | dark gray |
scattering matrix | 488 nm 647 nm |
