Stress caused these rocks to fracture. Stress is the force applied to an object. In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials. A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. WebRhyolite. Rhyolite is a felsic (silica-rich) volcanic igneous rock with the same mineral content as granite, only unlike granite, it cools fast from the molten rock near or over the surface of Earth's crust (extrusive type).When these magmas erupt, a rock with two grain sizes typically forms.

Observations … WebThe brittle–ductile transition zone is characterized by a change in rock failure mode, at an approximate average depth of 10–15 km (~ 6.2–9.3 miles) in continental crust, below which rock becomes less likely to fracture and more likely to deform ductilely. The zone exists because as depth increases confining pressure increases, and brittle strength increases …

In geology, shear is the response of a rock to deformation usually by compressive stress and forms particular textures. Shear can be homogeneous or non-homogeneous, and may be pure shear or simple shear. Study of geological shear is related to the study of structural geology, rock microstructure or rock texture and fault mechanics.
