kâsolidalls

Kâsolidalls is a term used to describe a rare variation of calcite crystals, a mineral form of calcium carbonate. These unique crystals are characterized by their distinctive swirling pattern, resembling the x-shaped marks of an Icelandic horse. This feature is due to the asymmetrical arrangement of calcite fibres within the crystal structure.

Kâsolidalls are typically found in countries with significant volcanic activity, particularly Iceland and other parts of the North Atlantic. The crystals form in areas where limestone meets volcanic rock, allowing for the exchange of ions and the creation of the distinctive x-shaped pattern.

The name "kâsolidalls" is derived from the Icelandic word 'kást,' meaning cup or calce, likely a reference to the scalene shape of the crystals. The term was first introduced by a geologist studying the unique crystals in the Westfjords region of Iceland.

Kâsolidall crystals are valued by collectors and rockhounds for their unique patterns and rarity. They are often found in conjunction with other minerals, such as staurolite, a mineral also known for its characteristic twinned crystals.

Research into the properties and formation of kâsolidalls is ongoing. Their study offers insights into the geological processes that shape the Earth's surface, particularly in regions of intense volcanic and tectonic activity.
