Crystal size is determined by several factors. However, it essentially boils down to rate of nucleation and rate of diffusion. A low nucleation rate with high diffusion rate will cause very large crystals to grow, whereas a high nucleation rate with low diffusion will cause very small crystals to grow.
Previously, it was commonly believed that cooling rate was a strong influence. The ideas was that if a melt took a long time to cool, crystals would have more time to grow. However, recent studies examining pegmatitic (very large crystals) rocks have shown that cooling of these bodies happens extremely quickly. One proposed explanation is that the amount of water present in the melt is much more important.

What factors causes the difference in the size of crystals formed?
factors include: saturation, rate of cooling, temperature, and the crystal itself...
What factors would cause a crystal to form?
weather and climate changes cause difference in size of crystals. or erosion
Is granite crystal or grain size?
granite's crystal size varies from 1 mm to 10 mm
What is the crystal size in a extrusive rock?
the size of crystals in extrusive roks

What determines the size of a mineral crystal formed from magma?
The rate at which magma cools determines the size of the mineral crystal.
Which crystal can help identify as igneous rock as intrusive or extrusive?
What is the effect of location on crystal size? Label the location of intrusive and extrusive igneous rocks on the diagram below. Then, illustrate the crystal size of the rock formed at that location in the appropriate callout circles.
What does mineral crystal size tell about how rock formed?
The size of the crystal relates to how long the crystals were forming. For example crystals that cooled slowly are larger than those cooling faster.
What affects th size of crystals formed from magma?
the slower the magma cools the bigger the crystal is
What is the difference between a crystal and a crystal system?
Crystal systems are the way in which unit cells are categorized according to their axial and dimensional symmetry while crystal structure refers to size, shape, and atomic arrangement within the lattice.
The shape of an ionic crystal depends on?
The mass of the ion, the charge on the ion and the ionic radius.
What is the difference between the virtual image formed by a convex lens and a concave lens?
The difference is that when virtual image is formed by the concave mirror...it is larger than its original size..but when it is formed by the convex mirror..it is smaller than the original size....
What is a crystal and what determines a crystals shape?
A crystal is a mineral where all of the atoms are in a row, this is what makes it kind of clear. What determines its shape is the amount of space it has to form in and will usually have triangular pyramidal edges.
What does crystal size indicate?
Crystal size in igneous rocks is generally a marker for how long magma or lava took to cool and solidify. Larger crystal size is indicative of slow cooling.
