Thornasite

Na12Th3(Si8O19)4·(H2O)12·6H2O
root IMA approved

Thornasite is a rare hydrated sodium thorium silicate mineral with the chemical formula Na12Th3(Si8O19)4·(H2O)12·6H2O. It belongs to the silicate class and is classified under the Strunz system as 9.GF.50. This mineral crystallizes in an unknown crystal system and is notable for its high thorium content, which is uncommon in silicate minerals. Thornasite is typically colorless or white and exhibits a vitreous to pearly luster. Its physical properties include a moderate to high density due to the presence of thorium, but its hardness and other specific properties are not well documented. It is considered a nesosilicate mineral.

Overview

Thornasite is a rare hydrated sodium thorium silicate mineral with the chemical formula Na12Th3(Si8O19)4·(H2O)12·6H2O. It belongs to the silicate class and is classified under the Strunz system as 9.GF.50. This mineral crystallizes in an unknown crystal system and is notable for its high thorium content, which is uncommon in silicate minerals. Thornasite is typically colorless or white and exhibits a vitreous to pearly luster. Its physical properties include a moderate to high density due to the presence of thorium, but its hardness and other specific properties are not well documented. It is considered a nesosilicate mineral.

Etymology

Thornasite is named after the element silicon, reflecting its chemical composition and the significance of silicon in its structure.

How to recognize it

Thornasite can be identified by its colorless to white color and vitreous to pearly luster. It is a relatively dense mineral due to its thorium content, though its exact hardness on the Mohs scale is not specified. It can be distinguished from other silicates by its unique chemical composition, particularly the presence of thorium. However, due to its rarity and lack of detailed physical properties, identification can be challenging without chemical analysis.

Trivia

Thornasite is notable for its high thorium content, which is rare in silicate minerals. It contains a significant amount of water in its structure, with a total of 18 water molecules per formula unit. Additionally, it is one of the few minerals named directly after an element, in this case, silicon, highlighting the importance of silicon in its composition.
