A: Basalt is a fine-grained volcanic rock that forms from the rapid cooling of lava at or near the Earth's surface. It is composed mostly of dark-colored minerals like pyroxene, plagioclase feldspar, and sometimes olivine. Basalt is typically dark in color, dense, and has a fine-grained texture.

In both basalt aggregates, the single cracks occurring in the coarser grain classes are mainly in the pattern of secondary olivine crystallization. In addition, single cracks are visible in the basalt aggregate 2, which are rather related to the weathering of the material and are original cracks unrelated to the crushing system of these aggregates.
