KRISTIANSENITE Meaning and
Definition
-
Kristiansenite is a mineral that belongs to the silicate group and is classified as a nesosilicate. It was first discovered in 1974 by Norwegian geologist Roald~V.~Kristiansen, after whom it was named. This rare mineral is typically found in pegmatite veins, which are coarse-grained igneous rocks that form during the final stages of magma crystallization.
The chemical composition of kristiansenite consists mainly of sodium, calcium, and aluminum, with additional elements such as boron and oxygen present. Its crystal structure is monoclinic, which means the mineral's crystals have three unequal axes in which one axis is inclined to the others. This gives kristiansenite unique physical and chemical properties that differentiate it from other minerals in its class.
Kristiansenite is characterized by its pale yellow to brownish color and its vitreous to greasy luster. Its hardness ranges from 5 to 6 on the Mohs scale, indicating a medium hardness. It has a perfect cleavage on {001}, which means it can split perfectly along a specific plane.
Due to its rarity and limited occurrence, kristiansenite does not have any significant economic uses. However, it plays a crucial role in advancing the understanding of mineralogy and geology. Its distinct characteristics and composition make it an interesting subject of study for scientists and mineral collectors alike.
Etymology of KRISTIANSENITE
The word "kristiansenite" is derived from the name of the Danish mineralogist, scientist, and geologist, Victor Moritz Goldschmidt. Goldschmidt named the mineral after the Norwegian geologist and petrologist, Niels Joachim Kristiansen. Therefore, it combines Goldschmidt's surname with the suffix "-ite", commonly used in mineral names, to indicate a mineral species.
