Properties of Rocks | Geology

The ultimate strength of a rock is determined by testing samples to destruction under compression, tension, flexure and shear. Many sandstones which in spite of a high quartz content have very little strength and will serve as examples of the dependence of the strength of a rock on the bonds between the mineral grains.
