Slate.
The mineral sample displayed a distinct cleavage, breaking along smooth, flat planes.
If a mineral lacks planes along which it may cleave, it will likely fracture instead of cleave. This means that the mineral will break irregularly and not along smooth, flat surfaces like in cleavage. The fracture pattern can vary depending on the mineral's physical properties.
The dominant form of breakage for sulfur is cleavage, where the mineral breaks along its natural planes of weakness. This results in the formation of smooth and flat surfaces.
Cleavage is the tendency of a mineral to break along planes of weak atomic bonding, resulting in smooth, flat surfaces, while fracture is the tendency of a mineral to break with rough, irregular surfaces. Cleavage results in smooth, reflective surfaces that reflect light, whereas fracture surfaces are dull and do not reflect light. Cleavage is a property that is characteristic of certain minerals and can be used for mineral identification, while fracture can vary depending on the specific conditions of the break and is less consistent across different minerals.
The difference between a mineral that has cleavage and one that has fracture is that cleavage is the tendency of some minerals to brake along flat surfaces and fracture is the tendency of some minerals to brake unevenly along curved or irregular surfaces.
The property illustrated by the peeling of biotite into thin flat sheets is called cleavage. Cleavage is a mineral's tendency to break along planes of weakness, resulting in smooth, flat surfaces. Biotite has perfect cleavage, which means it breaks easily into thin sheets.
The mineral property illustrated by the peeling of muscovite mica into thin sheets is cleavage. Cleavage is the tendency of a mineral to break along flat surfaces, producing smooth, flat fragments. In the case of muscovite mica, it has perfect cleavage in one direction, allowing it to be easily split into thin, flexible sheets.
Mica
cleavage
Mica is crystalline and forms layers.
Mica is a shiny mineral that occurs in sheets. It is composed of thin, flat sheets that can easily be peeled apart. Mica is commonly found in igneous and metamorphic rocks.
The mineral mica breaks evenly along flat sheets mainly because of its perfect basal cleavage, which is a result of its crystal structure. This cleavage allows mica to easily separate into thin, flat sheets when broken or cut.
The mineral that is flat with flaky cleavage is mica. Mica is a group of silicate minerals that can easily be split into thin sheets or flakes. These sheets have excellent cleavage, making them easily separable into thin layers.
Mica forms flat prisms that readily brakes into flakes.
Cleavage. Minerals with cleavage break along specific planes, resulting in smooth and flat surfaces. The number and angle of cleavage planes depend on the mineral's atomic structure.
Slate is a sedimentary rock that can be split horizontally to produce smooth flat surfaces that is often used as a roofing material.
