Rock strength is specified in terms of tensile strength, compressive strength, shear strength, and impact strength. In the context of fracture gradient, only the tensile strength of rock is of importance. The tensile strength of rock is defined as the pulling force, required to rupture a rock sample, divided by the sample's cross-sectional area.Web

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
