Crystal form refers to the geometric shape the mineral acquires upon solidification. Cleavage is a mineral property that describes the tendency of a crystal to break along planes of weakness.
The most useful physical properties for identifying minerals are color, luster, hardness, cleavage, fracture, streak, and specific gravity. These properties help geologists distinguish between different minerals based on their unique characteristics.
Flint does not have cleavage because it is a microcrystalline form of quartz and does not exhibit cleavage like minerals with well-defined crystal structures. Flint tends to fracture conchoidally, producing smooth curved surfaces when broken.
crystal shape
Calcium carbonate (CaCO3) would form a trigonal crystal system, commonly seen in minerals like calcite and aragonite. These crystals exhibit a rhombohedral shape with cleavage planes that intersect at oblique angles.
Cleavage is a physical characteristic determined by the arrangement of atoms within a mineral. Cleavage describes how a mineral breaks along planes of weakness due to its atomic structure, creating smooth, flat surfaces. The number and orientation of these planes are unique to each mineral.
All minerals have a crystal form, but not all have cleavage.
The mineral cleavage is made up of many other particles to form a rock when the rock cleavage is just a rock.
Yes. Quartz can have very well-formed crystals but lacks cleavage.

Crystals come in different shapes, determined by how the molecules of compounds from which they are made can be packed together. For instance a quarts crystal is hexagonal in shape, while galena and pyrites crystals are cubic. There are six different crystal shapes or forms determined by the axes and degree of symmetry of the crystal and the angles at which the axes intersect. Subordinate to the overall crystal shapes, many crystalline substances have within them planes of weakness along which the crystal may break these lines are related to the crystals symmetry and caused by how the molecules are aligned within the crystal. This is cleavage.
Obsidian does not have cleavage because of the way it forms. Obsidian is essentially nature's form of glass and so it has no regular or patterned crystal structure. Without that crystal structure, there is no cleavage.
Flint does not have cleavage because it is a microcrystalline form of quartz and does not exhibit cleavage like minerals with well-defined crystal structures. Flint tends to fracture conchoidally, producing smooth curved surfaces when broken.
Cleavage means to Split.Cleavage is most often used with the following 3 meanings:MITOSIS: a phase during Mitosis when cells split and multiplyGEOLOGY: The splitting of a complex crystal/mineral formation into a simpler oneINFORMAL USE: The viewable split between a woman's breasts
crystal shape
The overall three-dimensional solid structure that samples of compounds form is called a crystal lattice. This lattice structure is responsible for the properties of the crystal, such as its shape, cleavage, and density.
Calcium carbonate (CaCO3) would form a trigonal crystal system, commonly seen in minerals like calcite and aragonite. These crystals exhibit a rhombohedral shape with cleavage planes that intersect at oblique angles.
Streak. The 6 properties of minerals are streak, hardness, crystal form, color, cleavage/fracture, and luster. Hope that can answer your question:)
