Can rocks have cleavage?
Yes, rocks can have cleavage. Cleavage is the tendency of a mineral to break along smooth, parallel planes. It is a property commonly observed in minerals like mica and feldspar, which can be found in certain types of rocks such as schist and granite.
One way to test a mineral is to break it and see how many directions of what it has?

What is the cleavage of dolomite?
Dolomite typically exhibits three cleavage planes that intersect at approximately 90 degrees, resulting in rhombohedral cleavage.
Does granite have layers?
As granite is an igneous material, it would have to undergo a melt, taking away any form it has, such as cleavage. However, in a granite dike, the outer layer of the granite will be a chilled margin, giving it a glassy outer layer.
Does galena have a cleavage or a fracture?
It has both. It's cleavage is perfect, and it's fracture is sub-conchoidal.
What is the cleavage of granite?
Granite has no cleavage, it breaks off in crystals.
What is a granites cleavage?
Granite does not exhibit cleavage in the same way that some other minerals do, as it is an igneous rock composed mainly of quartz, feldspar, and mica. Instead, it has a granular texture and breaks in an irregular manner, typically showing a rough fracture. The mineral components within granite can have their own cleavage properties, but the rock itself lacks a distinct cleavage plane.
What are two minerals with cleavage?
Halite and Calcite. Halite has what is known as cubiccleavage, where there is cleavage in three directions at 90 degree angles. Calcite has what is known as rhombohedral cleavage, where there is cleavage in three directions but at 120 and 60 degree angles.
Can rocks have cleavage?
Yes, rocks can have cleavage. Cleavage is the tendency of a mineral to break along smooth, parallel planes. It is a property commonly observed in minerals like mica and feldspar, which can be found in certain types of rocks such as schist and granite.
What is the Flaky dark mineral found in granite?
The flaky dark mineral commonly found in granite is biotite. Biotite is a mica mineral that typically appears as black or dark brown flakes and is characterized by its perfect cleavage, allowing it to be easily split into thin sheets. It contributes to the overall texture and mineral composition of granite, alongside quartz and feldspar.
How are mineral fracture and mineral cleavage different?
Cleavage in minerals is the tendency of the mineral to break across a definite plane, creating a smooth surface. Two minerals with cleavage are granite and shale.
What is sulfurs cleavage cleavage?
Sulfur's cleavage is imperfect.
