About: Vanarsite

An Entity of Type: mineral, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Vanarsite, NaCa12(As3+V4+3.5V5+8.5As5+6O51)2・78H2O, is a mineral that forms as very dark blue blades that are flattened on {100} and elongated on [010]. The crystals form in sub-parallel intergrowths in aggregates up to 5 mm long and are part of the cubic crystal system. The mineral is found in the Packrat mine in Colorado, USA in association with three mineral of similar composition, packratite, Ca11(As3+V4+2V5+10As5+6O51)2・83H2O, morrisonite, Ca6(As3+V4+2V5+10As5+6O51)2・78H2O, and gatewayite, Ca11(As3+V4+3V5+9As5+6O51)・31H2O. Vanarsite has been determined to be part of the vanadate, arsenite, and arsenate groups. Analytical methods were used to determine its chemical composition, physical properties, and structure.
