Basalt rock is fine-grained, dark-colored volcanic rock with essentially Mg-rich plagioclase and augite. It is basic or low in silica (42-52 wt. %) mafic (Mg- and Fe-rich) rock, with relatively low amounts of total alkalis (Na 2 O and K 2 O). To identify this rock in the field, consider its colors and texture.Web

compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2.Web
