What type of cleavage does feldspar have?
Plagioclase feldspar is a non-metallic mineral. It has 2 cleavages at nearly right angles. It is also differentiated from potassium feldspar because it contains striations. Potassium feldspar has 2 cleavages at nearly right angles.
What is the fracture of feldspar?
Feldspar's fracture is brittle
Skin cuts parallel gape less?
cleavage lines
What is a Minerals ability to split easily along a flat surface?
Cleavage .
What is the shape of a mineral that has three directions of cleavage that intersect at 90 degrees?
cube
Is a cleavage a property of a mineral?
feldspar
What common mineral breaks with cleavage?
Feldspar.
Which mineral has a hardness of 6 and has cleavage?
Orthoclase Feldspar.
What is Feldspars cleavage?
2 at 90 degreesHere is a discussion on feldspar.It says it has uneven fracture and cleavage in 2 directions.http://www.theimage.com/mineral/feldspar/index.htm

What mineral properties would you use to tell the difference between quartz and feldspar?
Cleavage and Fracture
Examines a mineral's ability to break into even pieces?
Cleavage is a minerals ability to break into even pieces useful for identification. Cleavage in two directions equals Feldspar for example.
Step like cleavage is a property of what mineral?
Step-like cleavage is a property of the mineral mica. Mica minerals exhibit a planar arrangement of atoms that allow them to easily separate along flat surfaces, giving them a distinctive step-like appearance when broken or cleaved.
How many directions of cleavage do the feldspar minerals have?
Feldspar minerals typically exhibit two directions of cleavage at nearly 90 degrees to each other. This cleavage produces flat surfaces that intersect at right angles.
Do Orthoclase and plagioclase feldspars have quite different forms of cleavage?
Orthoclase feldspar typically exhibits two cleavage planes at right angles to each other, forming blocky or prismatic shapes. Plagioclase feldspar, on the other hand, shows two cleavages at nearly 90 degrees but often also has a third cleavage at a slightly different angle, resulting in more varied forms.
How does the cleavage of feldspar differ from the cleavage of mica?
Feldspar typically displays two cleavage planes at nearly right angles, forming a rectangular shape, due to its two prominent cleavage directions. In contrast, mica exhibits a single perfect cleavage plane which allows the mineral to be easily split into thin, flexible sheets.
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.
