THOMSONITE
* fine crystals (size 4-5mm) on matrix *
* nice specimen from very uncommon locality *
size: 61 X 49 X 36mm
weight: 95g
3D4
origin: Jezerní Mt, Klášterec nad Ohří, Krušné Hory Mts (Erzgebirge), Ústí Region, Bohemia, Czech Republic Thomsonite is one of the rarer zeolites. It forms tight acicular radiating clusters and sphericules as well as some blockier crystals that are found in the vesicles or bubbles of volcanic rock as are m...ost other zeolites. Natrolite, another zeolite, is usually square in cross section but is otherwise difficult to distinguish from thomsonite. The color is usually colorless or white, but a few specimens have shown a lovely yellow color. Thomsonite is a rare mineral and is sought after by collectors of rare zeolite minerals. Zeolites are known to have an openness about their structure that allows large ions and molecules to reside and actually move around inside the overall framework. The structure actually contains open channels that allow water and large ions to travel into and out of the crystal structure. The size of these channels controls the size of the molecules or ions and therefore a zeolite can act as a chemical sieve, allowing some ions to pass through while blocking others.
