Hexagonal & Triclinic System

Hexagonal system
The hexagonal crystal system and this is one of the seven pattern point groups. It has the same symmetry as a right prism with a hexagonal base. There is only one hexagonal bravais lattice, which has six atoms per unit cell. Graphite is an example of a crystal that crystallizes in the hexagonal crystal system. Hexagonal arrangements have also been seen in systems of amphiphiles and make up one of the kinds of lipid polymorphism. The orthorhombic system consists of crystals that have three axes that are at right angles but all of them have a different length. The monoclinic system has three axes that all have diverse lengths. Two of these come together at right angles whereas the third has an oblique angle to the other ones.

Triclinic system
The triclinic system is made up of three axes that are diverse in length and all cross at slanted angles. Along with the systems that crystals are recognized with, these also form into diverse, precise shapes that are identified as habits. A few of the most recognized ones are tabular, cubic and column. Nonetheless it is not as definite a categorizing characteristic as it might seem. Habits can modify because of temperature, pressure, composition of the solutions from which the minerals crystallize, dissimilarities in composition of minerals and adulterations in the mineral etc. for example, fluorite crystals, that are a member of the isometric system, might be in the cubic habit if they were formed in lower temperatures but in many cases they show up in the octahedral form if they were created in more elevated temperatures. Crystals that are looked at with the naked eye, or those that are looked at under a magnifying glass, in most cases typically identify a mineral, on the other hand a mineral will in many occasions challenge categorization this way mostly because of the alterations that it has had due to erosion or fracturing, such as in how little the crystal is, or the chemical action that the metallic crystal had and so forth. For a good number of years now, geologists and experts have come up with a basic system of testing so as to make out the physical properties of minerals in the field in order for these to be recognized with only uncomplicated technical equipment and this is done through a method of elimination.
