Garnet: The mineral Garnet information and pictures

Garnet is not a single mineral, but a group contains closely related, isomorphous minerals that form a series with each other. The Garnet members form intermediary minerals between each member, and may even intergrow within a single crystal. The Garnets vary only slightly in physical properties, and some of the members may be so similar that they are indistinguishable from one another without ...

Background - Cleavage and fracture are both patterns of breakage.. Minerals with cleavage break along planar (flat) surfaces of weaker chemical bonds. When minerals break to expose large, flat surfaces, cleavage is said to be good to excellent.. Conchoidal fracture differs from cleavage because the broken surface is not a smooth, flat plane.. Conchoidal fracture is easily recognized and named ...

do garnet have cleavage or fracture

Fracture is a break in a mineral that is not along a cleavage plane. Fracture is not always the same in the same mineral because fracture is not determined by the structure of the mineral. Minerals may have characteristic fractures (Figure 9). Metals usually fracture into jagged edges. If a mineral splinters like wood, it may be fibrous.

garnet fracture

The mineral pyrope is a member of the garnet group. Pyrope is the only member of the garnet family to always display red colouration in natural samples, and it is from this characteristic that it gets its name: from the Greek for fire and eye.Despite being less common than most garnets, it is a widely used gemstone with numerous alternative names, some of which are misnomers.

Cleavage and fracture differ in that cleavage is the break of a crystal face where a new face (resulting in a smooth plane) is formed, whereas fracture is the "chipping" shape of a mineral. All minerals exhibit a fracture, even those that exhibit cleavage. If a mineral with cleavage is chipped a certain way, it will fracture rather than cleave.

Macroscopic Aspects of Fracture :: Total Materia Article

Fracture is an inhomogeneous form of deformation which can be viewed on different levels. On an atomistic level it occurs by the breaking of atomic bonds, either perpendicular to a plane (cleavage) or across a plane (shear). On a microscopic level cleavage occurs by the formation and propagation of microcracks and the separation of grains along ...

Odor: Mineral Properties - The Mineral and Gemstone Kingdom

ODOR. Several minerals give off a distinctive odor in certain conditions. Sulfur specimens, in normal room conditions, give off a mild odor resembling the smell of a lighting match. However if heated or struck, they will give off a powerful odor like rotten eggs. Many sulfides, such as Pyrite, also give off a rotten-egg odor if heated or struck.
