What are the 7 properties mineralogist use to identify ninerals?
Colour - however, this can be a very misleading property. Transparency - Is the crystal transparent, translucent or opaque Lustre - how shiney is the crystal is, there are various different types of lustre. Hardness - Expressed in a number between 0 and 10 on the Moh scale. Streak - the colour of the mineral in powdered form. Easily testable by scratching the mineral on a porcelain plate. Cleavage - Very characteristic to a mineral is what the preferred cleavage is. Mode of occurrence - Is it like needles, fibre, tabular, prismatic, etc.
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.
Which mineral is a perfect square?
No mineral can be a perfect square: which is a two dimensional figure.No mineral can be a perfect square: which is a two dimensional figure.No mineral can be a perfect square: which is a two dimensional figure.No mineral can be a perfect square: which is a two dimensional figure.
What is the natural shape of a mineral?
The natural shape of a mineral would be its crystalline structure.
What term is used to describe the shape of a mineral that has three directions of cleavage that intersect at 90?
The term used to describe the shape of a mineral with three directions of cleavage that intersect at 90 degrees is cubic or isometric cleavage. This means that the mineral can cleave in three directions at right angles to each other, resulting in cubic-shaped fragments.

One way to test a mineral is to break it and see how many directions of what it has?
cleavage....
How many directions of cleavage do the feldspar minerals have?
Two directions of cleavage, at 90 degrees to each other.
What is the ability of a mineral to break along preferred directions called?
The ability of a mineral to break along preferred directions is called cleavage. Cleavage is a result of the arrangement of atoms within the mineral structure, which causes it to break in certain directions more easily than others.
Which mineral has perfect cleavage in six direction diamond fluorite sodalite and sphalerite?
Diamond has perfect cleavage in four directions, fluorite has perfect cleavage in four directions, sodalite has perfect cleavage in three directions, and sphalerite has perfect cleavage in six directions.
One way to test a mineral is to break it and see how many directions of what it what?
...directions of cleavage...
A mineral that splits along a flat surface in 3 directions is?
Muscovite is a mineral that splits along a flat surface in 3 directions due to its perfect cleavage. This mineral belongs to the mica group and is commonly found in metamorphic rocks.
How can one identify cleavage in minerals?
Cleavage in minerals can be identified by observing how the mineral breaks along certain planes or directions, resulting in smooth, flat surfaces. This cleavage is a result of the internal atomic structure of the mineral. By examining the shape and pattern of the breakage, one can determine the cleavage of a mineral.
What mineral has a cleavage that goes in 90 degree angles in three directions?
Rock salt.
What does the presence of cleavage planes within a mineral tell you about the chemical bonds that hold a mineral together?
minerals with cleavage break along smooth, flat surfaces in one or more directions.
What examines a mineral's ability to break into even pieces?
Cleavage is the property that examines a mineral's ability to break into even pieces along specific planes or directions. Minerals with good cleavage will break cleanly and smoothly along these planes, while minerals with poor cleavage will break in irregular or jagged shapes. Cleavage is determined by the internal atomic structure of a mineral.
