Tväskivihoulderita

Tväskivihoulderita is a rare mineral discovered in the Tväskivi region of Finland. It belongs to the silicate group, characterized by its complex crystal structure containing silicon, oxygen, and various metal cations. The mineral typically appears as small, prismatic crystals, often found embedded within larger rock formations. Its color can range from pale green to a more intense emerald hue, depending on the presence and concentration of trace elements, particularly iron and magnesium.

The formation of tväskivihoulderita is believed to occur under high-pressure, high-temperature metamorphic conditions deep within the Earth's crust. Its geological context suggests it forms during the metamorphism of specific rock types, such as certain types of schists and gneisses. The mineral is not known to be of significant economic importance, and its primary value lies in its scientific interest for mineralogists and geologists studying metamorphic processes and rare mineral occurrences.

Analysis of tväskivihoulderita has revealed a unique chemical composition that distinguishes it from other known silicate minerals. The specific arrangement of atoms within its crystal lattice is a subject of ongoing research, aiming to understand the physical properties that arise from this structure. While deposits are limited to the Tväskivi area, isolated occurrences have been reported in other geologically similar regions, though these are exceptionally rare.
