Anorthitic - English Definition & Meaning

Definition

Anorthitic describes a type of plagioclase feldspar, which is a rock-forming mineral. This mineral is rich in calcium and is an endmember of the plagioclase series. Picture it as the calcium-heavy sibling in a mineral family. Anorthitic feldspar is typically found in igneous rocks, especially those formed in volcanic environments. It's important in geology for understanding the composition and origin of rocks. Its presence can tell geologists about the conditions under which the rock was formed.

Etymology

The name 'anorthite' comes from the Greek word 'anorthos,' meaning 'oblique.' This refers to the mineral's triclinic crystal system, which means its crystal axes are of unequal lengths and none are at right angles. The suffix '-itic' is added to denote that it is a rock or mineral. The name highlights a key characteristic of the mineral's structure.
