LEMANSKIITE Meaning and
Definition
-
Lemanskiite is a rare mineral that belongs to the cyclosilicate family. It was first discovered in 1979 in the Yukspor Massif, Kola Peninsula, Russia, and was named after professor Richard A. LeManski, a prominent mineralogist. Lemanskiite is classified as a member of the cancrinite group of minerals.
This mineral is known for its distinctive crystal structure, which consists of large 24-membered rings of silicate tetrahedra interconnected by sodium, calcium, and aluminum cations. It typically occurs in syenitic rocks and nepheline syenites, which are alkaline intrusive igneous rocks rich in feldspar and feldspathoid minerals.
Lemanskiite is usually found in the form of prismatic crystals, which can range in color from yellowish to yellow-brown, translucent to opaque. Its luster is vitreous, and it possesses a brittle tenacity. The hardness of lemanskiite on the Mohs scale is approximately 5.5-6, indicating its moderate resistance to scratching.
Due to its rarity and limited occurrence, lemanskiite has few practical applications. However, it is highly valued by mineral collectors and enthusiasts due to its unique crystal structure and distinct yellowish coloration. Its study and analysis also contribute to our understanding of mineralogical processes and the formation of cyclosilicates, aiding in geological research.
Overall, lemanskiite is an intriguing mineral that showcases the diverse and fascinating world of cyclosilicate minerals, and its aesthetic appeal adds to its significance in the field of mineralogy.
Etymology of LEMANSKIITE
The word "lemanskiite" is derived from the name of the locality where it was first discovered, Le Manskiy District in Yakutia, Russia. It is a mineral named in honor of this locality. The suffix "-ite" is a common mineral naming convention, indicating that it is a type of mineral.
