What are the parallel lines seen on crystal faces or cleavage planes?
These are called striations.
What is a minerals cleavage?
Cleavage is the tendency of a mineral to break along smooth planes parallel to zones of weak bonding.
Is shale fracture or cleavage?
the cleavage is Poor
What are crystal form and cleavage?
Crystals come in different shapes, determined by how the molecules of compounds from which they are made can be packed together. For instance a quarts crystal is hexagonal in shape, while galena and pyrites crystals are cubic. There are six different crystal shapes or forms determined by the axes and degree of symmetry of the crystal and the angles at which the axes intersect. Subordinate to the overall crystal shapes, many crystalline substances have within them planes of weakness along which the crystal may break these lines are related to the crystals symmetry and caused by how the molecules are aligned within the crystal. This is cleavage.
Does mica have clear cleavage?
As Mica splits perfectly parallel to its base, it is considered to have perfect basal cleavage. No other cleavage planes are present in Mica so the flaking occurs readily along this single plane. A good analogy would be a stack of A4 paper. The layers are easily peelable in one direction [parallel to the base] as opposed to the other axis [refer to the miller indices].
What are the parallel lines seen on crystal faces or cleavage planes?
These are called striations.
What is mineral's cleavage?
Cleavage is the tendency of a mineral to break along smooth planes parallel to zones of weak bonding.
What is a minerals cleavage?
Cleavage is the tendency of a mineral to break along smooth planes parallel to zones of weak bonding.
Can rocks have cleavage?
Yes. Cleavage (referring to rocks) is the tendency to break along its crystal planes, thus reflecting it's mineralogy. Not all rocks have cleavage.
What is the difference between crystal form and cleavage?
Crystal form refers to the geometric shape the mineral acquires upon solidification. Cleavage is a mineral property that describes the tendency of a crystal to break along planes of weakness.
What are the observations of marble?
it has no cleavage planes, and fractures in tiny crystal sizes so its ideal for sculpting with
Why does cleavage occur?
Cleavage means to Split.Cleavage is most often used with the following 3 meanings:MITOSIS: a phase during Mitosis when cells split and multiplyGEOLOGY: The splitting of a complex crystal/mineral formation into a simpler oneINFORMAL USE: The viewable split between a woman's breasts
What is salt's cleavage?
The rocks tend to spilt along parallel planes defined by distribution and parallel arrangment of platy mineral crystals.
When a mineral breaks along a weekly bonds plane it is called?
cleavage.
Can you have skew planes?
No, they are either parallel, or they intersect
Tendency to break along smooth flat surfaces?
Many minerals have "cleavage" that causes them to split on flat cleavage planes. Such minerals include micas (muscovite, biotite. phlogopite), calcite, gypsum, and feldspars. Cleavage is the result of the minerals' crystal structure that has weaker chemical bonds aligned in planes.
What is cleaveges?
In case of sodium chloride crystal we have sodium positive ions and chloride negative ions have been arranged in a perfect order. As we break the crystal then it gets broken only at some definite planes containing these ions. Hence these planes have been named as cleavage planes. The other name for these planes is lattice planes.
