Calcite has excellent cleavage in 3 directions, although they are not at 90 degrees. It can form prisms, rhombohedrons, or scalenohedrons that break into rhombohedrons.

What is the cleavage of talc?
talc's cleavage is perfect in one direction, basal.
What cleavage is talc?
Perfect in one direction but often does not show.
What is cleavage in anatomy?
Cleavage is a mineral's tendency to break along flat, parallel surfaces (cleavage planes). Excellent cleavage direction reflects light in one direction, it is considered basal, or book cleavage. Biotite and muscovite have excellent cleavage. Good cleavage reflects light in one direction from a set of many small flat surfaces, augite and gypsum are examples. Poor cleavage directions reflect light form surfaces that are hard to detect, and this is true for sulfur.
What is Fluorite Or what is Fluorite used for?
its is a rock
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.
Which mineral has perfect cleavage in six direction diamond fluorite sodalite and sphalerite?
Sphalerite
Does fluorite have cleavage?
Yes; Fluorite has cleavage; it breaks along flat surfaces in three directions.
What is the cleavage of fluorite?
Perfect in three directions.
Does fluorite have cleavage or fracture?
It has both: uneven fracture, and perfect cleavage in three directions.
What is the Breakage of fluorite?
I think that the breakage of fluorite would be cleavage because it is cut in a direct way.
What minerals have only one direction of cleavage?
Mica minerals have only one direction of cleavage. Examples are Muscovite and Biotite.
What is the cleavage of talc?
talc's cleavage is perfect in one direction, basal.
What has cleavage in One Direction?
haha ummmm a ROCK
What Is the tendency of mineral to break into irregular pieces?
This is termed fracture, eg. the conchoidal fracture of obsidian. Breaking into pieces with straight lines and flat faces is called cleavage; minerals like calcite and fluorite exhibit excellent cleavage.
Mica has one direction of what so it breaks into sheets?
Cleavage
Mica has one direction of so it breaks into sheets?
cleavage
Why do some minerals break by fracturing?
Minerals can have a cleavage plane, multiple cleavage planes, or no cleavage plane. A cleavage plane is an area of weakness in the crystalline structure where the mineral is prone to splitting.
