Triclinic Crystal System

Crystallographic Axes: Some minerals like axinite, albite, anorthite, microcline, and kyanite crystallize in the triclinic system. The crystal forms of the triclinic system are referred to as three unequal axes that make oblique angles with each other. The angles between the positive ends of ‘b’ and ‘c’, the ‘c’ and ‘a’, and the ‘a’ and …

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 …
