Structure and properties. Basalt is a common extrusive volcanic rock, which is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic, containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey.

When considering plain concrete as a benchmark, the increment of dynamic MOE is 13.83% at the peak (0.25%). The dynamic MOE then sees a continuous decline with a slower slope than the rising slope. In comparison, when adding 0.5% of basalt fiber, the dynamic MOE is 29.86 GPa, which is lower than the M2 (0.25%) value.
Basalt from this region produces fibers with the qualities needed to make strong composites. [10] One study looked at the use of basalt fiber composites for fire protection. This study cites the high temperature capabilities and relatively low cost of basalt fibers. A flame test was performed with an oxyacetylene torch.
