PARGASITE Meaning and Definition

1. Pargasite is a complex mineral belonging to the amphibole group, named after its type locality in Pargas, Finland. It is a silicate mineral that typically occurs in metamorphic rocks, particularly in high-grade metamorphic environments. The mineral crystallizes in the monoclinic system and is commonly found as prismatic or fibrous crystals.

   Chemically, pargasite is characterized as a sodium-calcium-magnesium iron aluminum silicate hydroxide. It has a general formula of (NaCa)(Mg,Fe2+)(Mg,Fe2+,Al)5Al(Si6Al2)O22(OH)2. The variation in composition leads to different end-members and intermediate compositions within the pargasite group.

   Pargasite typically exhibits a glossy or vitreous luster and can appear in various colors, including green, yellow, brown, or black. Its color variations are attributed to impurities or trace elements present within the crystal lattice.

   The mineral has good cleavage in two directions, forming prismatic or bladed crystals. It is also commonly found in aggregates or fibrous forms. Pargasite is relatively hard, with a Mohs hardness ranging from 5 to 6, making it suitable for various industrial uses.

   In terms of its geological significance, pargasite is an excellent indicator of specific metamorphic conditions and can provide valuable information about the temperature and pressure history of the rocks in which it occurs. Its presence or absence can aid in understanding the geological processes involved in the formation of metamorphic terrains.

2. A term to designate those varieties of hornblende possessed of a high lustre.
