It is a large sandstone rock split neatly down the middle into two parts, both balanced on small pedestals. [1] The overall shape of the rock is due to wind erosion and the chemical weathering made possible by the moist conditions in the protected underside of the rock. [2] It is split in two by a joint.
Lithops is a genus of succulent plants in the ice plant family, Aizoaceae.Members of the genus are native to southern Africa.They avoid being eaten by herbivores with their camouflage as small stones, and are often known as pebble plants or living stones.
While Eitzman had already suggested the pebble was brought to the cave because of the resemblance to a face, Dart recognized other faces when the stone is viewed from different angles. [1] The Makapansgat pebble cannot be seen as art if a usual definition of the term is used, as the object was found and not made. Nevertheless, that an ...
The stone is first examined to determine the direction of the grain and to identify any potential defects. After the location of the intended split is chosen, a line is scored on the surface of the stone. A number of holes are then cut or drilled into the stone face along the scored line approximately 10 to 20 centimetres (3.9 to 7.9 in) apart.
The churn is a Modified Gothic style structure with Indiana split face stone located on Westphalia street in Westphalia, Michigan. It is also designated as a Michigan State Historic Site. Along with the church, St. Mary Parish facilities include an elementary school, youth center, funeral chapel, parish center, cemetery, rosary garden, and ...
Cleavage, in mineralogy and materials science, is the tendency of crystalline materials to split along definite crystallographic structural planes. These planes of relative weakness are a result of the regular locations of atoms and ions in the crystal, which create smooth repeating surfaces that are visible both in the microscope and to the ...

Schistosity is a thin layering of the rock produced by metamorphism (a foliation) that permits the rock to easily be split into flakes or slabs less than 5 to 10 millimeters (0.2 to 0.4 in) thick. [ 4 ] [ 5 ] The mineral grains in a schist are typically from 0.25 to 2 millimeters (0.01 to 0.08 in) in size [ 6 ] and so are easily seen with a 10 ...
