Igneous rocks, their classification, composition, formation, texture & uses 1) coarse grained or phaneritic if the average grains or crystals of the minerals are more than 5mm in diameter, the rock is said to be coarser grained igneous rocks.
In a simplified classification, igneous rock types are separated on the basis of the type of feldspar present, the presence or absence of quartz, and in rocks with no feldspar or quartz, the type of iron or magnesium minerals present rocks containing quartz (silica in composition) are silica-oversaturated.

Crystal systems: atoms in a crystal bond into specific shapes and patterns know as systems the four types of crystals may appear as one of seven structural/system types: cubic, hexagonal, tetragonal, orthorhombic, trigonal, monoclinic and triclinic.
The classification and formation of crystals introduction purpose my purpose of this experiment is to find out how crystals are formed and how they are classified. Rock candy, the crystalline form of table sugar or sucrose, is an example of a molecular crystal as with the lattice classification system, this system isn't completely cut-and-dried sometimes it's hard to categorize crystals as belonging to one class as opposed to another see pictures of different types of crystals what chemicals grow.
