Spaltbildning

Spaltbildning, also known as "splitting" or "cleavage," is a geological process where rocks break along planes of weakness, resulting in distinct, flat surfaces. This phenomenon is commonly observed in minerals and rocks, and it is a result of the anisotropic nature of their internal structure. The planes of weakness are often aligned with the crystal lattice of the mineral, and the angle between these planes is known as the cleavage angle. The number of cleavage planes can vary, ranging from one to six, and is a characteristic property of minerals. Cleavage is an important diagnostic feature in mineral identification and is used in various fields, including geology, materials science, and crystallography. It is also a significant factor in the formation of geological structures, such as faults and joints, which can influence the behavior of rocks in engineering and construction projects.
