Orthorhombic Crystal System

Some common minerals like Baryte, Olivine, Andalusive, and Topaz belong to this type of crystal system. Crystallographic Axes: Crystals belonging to the orthorhombic system are referred to as three unequal, mutually perpendicular axes. The ‘a axis being shorter is called ”brachy axis” and the ‘b’ axis being longer is called ”macro axis”. Classes of Orthorhombic …

Tetragonal Crystal System

In our previous post, we discussed in detail the classes and forms of Cubic/ Isometric Crystal System, which is a very common type of crystal and includes hundreds of minerals in this system. This post is about the ”tetragonal crystal system”. The tetragonal crystal system is another important system. Zircon, Cassiterite, and Rutile are the …
