Halite is a cleavage because it splits evenly, but fracture would mean it breaks irregularly.
Halite is a cleavage because it splits evenly, but fracture would mean it breaks irregularly.
Halite typically displays cleavage along three planes at right angles to each other. However, if halite is subjected to mechanical stress, it can also exhibit a conchoidal fracture pattern due to its brittle nature.
Halite fractures conchoidally, meaning it breaks into smooth, curved surfaces similar to a clamshell. This type of fracture is characteristic of brittle minerals with no preferred cleavage direction.
Cleavage is a property of minerals. Sandstone is a rock type. As such it doesn't have the property of cleavage.Cleavage is a metamorphic fabric. Sandstone is not a metamorphic rock and thus can not display a cleavage.
Quartz does not have cleavage. However, it does have fracture. Its fracture is conchoidal.
Halite will be easily soluble in water, calcite won't. Calcite has excellent rhombohedral cleavage, halite has excellent cubic cleavage. Halite will taste salty, calcite won't.

cleavage
Halite typically exhibits perfect cubic cleavage, meaning it breaks into perfect cubes or square shapes along its crystal planes. This cleavage is a defining characteristic of halite and can be observed by examining the broken surfaces of the mineral.
Fracture
Hematite has a characteristic fracture, meaning it breaks irregularly with rough or jagged edges and no smooth cleavage planes.
