How does the cleavage of feldspar differ from the cleavage of mica?
Biotite (black mica) and muscovite (white mica) are both minerals that have perfect basal cleavage--one direction. It cleaves into thin sheets. Feldspars (albite, oligoclase, andesine, labradorite, bytownite, anorthite) have good cleavage in two directions at nearly right angles, poor in a third direction.
Mica has one direction of what so it breaks into sheets?
Cleavage
Mica has one direction of so it breaks into sheets?
cleavage
What mineral has cubic cleavage?
An example of rhombic cleavage would be siderite and rhodochrosite. Remember that this is basically a "partically squashed box." Essentially, the direction of deformation in a rhombohedron occurs in one of the three diagonals that run from one corner of the cube to the other. Calcite is not a particularly fabulous example of a rhombohedron, because it is considered to be cubed.
Is cleavage sexy?
In one sense, cleavage is the hollow space between a woman's breasts revealed by a low neckline. Most women develop the appearance of cleavage although less endowed women can create and enhance cleavage with a variety of underwired and padded undergarments designed to push up and push together their breasts. The word "cleavage" in geology is used only to describe the morphology of fractures in minerals. Minerals have a cleavage, if they form flat, planal fractures along certain planes in their crystal lattice.
Compare and contrast a mineral fragment that has one cleavege direction with one that has only fracture?
One that has only one cleavage direction will only fracture in one direction/angle to the matrix of the rock. One that only has fracture would fracture in no specific direction and is probably something like obsidian, which fractures conchoidally, like glass.
Does serpentine have Cleavage or fracture?
Serpentine is a general name for 5 different minerals. These are antigorite, clinochrysotile, lizardite, orthochrysotile, and parachrysotile. Antigorite and lizardite have cleavage in one direction. The others have fracture.

What is a minerals cleavage?
Cleavage is the tendency of a mineral to break along smooth planes parallel to zones of weak bonding.
What is a pearl's cleavage?
Cleavage is a plane of atomic weakness in an inorganic mineral. Since pearls are an organic gem, they cannot have cleavage. The fracture surface of a pearl can be described as conchoidal.
What has cleavage in One Direction?
haha ummmm a ROCK
What cleavage is talc?
Perfect in one direction but often does not show.

What s the difference between a mineral that has cleavage and one that has fracture?
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.
What is the cleavage of talc?
talc's cleavage is perfect in one direction, basal.
Cleavage of a mineral is related to what?
Cleavage is a smooth and easy break in a mineral. Minerals are always solid because it is one of their classification requirements.
