NaSr2Al5Si5O20·(6-7)H2O
Orthorhombic heart IMA approved

Thomsonite-Sr is a hydrated sodium strontium aluminosilicate mineral with the chemical formula NaSr2Al5Si5O20·(6-7)H2O. It belongs to the inosilicate class and is part of the thomsonite group. The mineral crystallizes in the orthorhombic system and is typically found in fibrous or prismatic forms. It exhibits a vitreous to pearly luster and is usually white, gray, or pale green in color. With a hardness of approximately 5.5 to 6 on the Mohs scale and a moderate density, thomsonite-Sr is a relatively soft and lightweight mineral. It is commonly associated with other zeolite minerals in low-temperature environments.

Overview

Thomsonite-Sr is a hydrated sodium strontium aluminosilicate mineral with the chemical formula NaSr2Al5Si5O20·(6-7)H2O. It belongs to the inosilicate class and is part of the thomsonite group.

Etymology

Thomsonite-Sr is named after the mineral thomsonite, which in turn was named in honor of Sir William Thomson (Lord Kelvin). The -Sr suffix indicates the presence of strontium in its composition. No specific discovery year is provided in the facts.

How to recognize it

Thomsonite-Sr can be identified by its moderate hardness of 5.5 to 6 on the Mohs scale, its vitreous to pearly luster, and its pale coloration, which is often white, gray, or pale green. It may be distinguished from other zeolites by its specific gravity and the presence of strontium in its chemical composition. It can sometimes be confused with similar fibrous or prismatic zeolites, but its chemical analysis is key to accurate identification.

Trivia

Thomsonite-Sr is notable for its unique chemical composition, which includes strontium, a relatively rare element in zeolite minerals. It belongs to the orthorhombic crystal system, which is less common among zeolites. The mineral is part of the thomsonite group, a family of hydrated aluminosilicates with complex structures.
