Basalt Basalt is a mafic extrusive rock is the most widespread of all igneous rocks and comprises more than 90 of all volcanic rocks Because of its relatively low silica content basalt lava has a comparatively low viscosity and forms thin flows that can travel long distances
Basalt Wikipedia
Basalt is one of the most common rock types in the world Basalt is the rock most typical of large igneous provinces The largest occurrences of basalt are in the ocean floor that is almost completely made up by basalt Above sea level basalt is common in hotspot islands and around volcanic arcs specially those on thin crust
a study to try to explain the behavior of dust as a cohesive soil on the moon when it should have behaved as a cohesionless soil since no moisture is present on the moon1S surface It is well known that moisture is required on earth for fine grained soil to exhibit the very complex physicochemical soil mechanics phenomenon known as cohesion
