What else can I help you with?
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 are the 5 properties?
the 5 properties are cleavage hardness luster color streak
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
How is a calcite or feldspar inditified?
Calcite can be identified by its rhombohedral cleavage and effervescence in acid. Feldspar can be identified by its two cleavage planes at nearly 90 degrees, and it often has a white to pink color. Both minerals can also be identified by their hardness using the Mohs scale.
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.
How many directions of cleavage do the feldspar minerals have?
Two directions of cleavage, at 90 degrees to each other.
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.
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?
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.
