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
What term is used to describe the shape of a mineral that has three directions of cleavage that intersect at 90 angles?
The term used to describe the shape of a mineral that has three directions of cleavage intersecting at 90-degree angles is "cubic" or "isometric." Minerals that exhibit this type of cleavage typically form cubic crystal systems, such as halite or pyrite. This characteristic cleavage results in the mineral breaking along smooth, flat surfaces that create cube-shaped fragments.

What is feldspar used for in everyday life?
Feldspar is commonly used in the production of ceramics and glass, contributing to their strength and durability. It's also utilized as a filler in paints, plastics, and rubber to improve texture and enhance properties. Additionally, feldspar plays a role in the manufacturing of tiles and sanitary ware, making it an essential material in construction and home decor.
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 the cleavege of feldspar?
Feldspar exhibits two directions of perfect cleavage that intersect at approximately 90 degrees. This characteristic allows feldspar crystals to break along these planes, resulting in smooth surfaces. The cleavages are typically observed in two forms: one that is more prominent and can be seen in plagioclase feldspar, and another that is more subtle in potassium feldspar. This cleavage is a key diagnostic feature in identifying feldspar minerals.
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 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 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.
