Jadarite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
LiNaSiB3O7(OH)
System:
Monoclinic
Colour:
White
Hardness:
4 - 5
Name:
After the type locality, the Jadar Basin, Serbia, where it was discovered during mineral explorations.
It has been widely reported in the media that this mineral has a similar composition to the mythical "Kryptonite" of Superman fame. That claims to be a "sodium lithium boron silicate hydroxide with fluorine", and Jadarite is similar (except it does not contain fluorine).

So far the effects of Jadarite on superheroes have not been noted by researchers.

Classification of Jadarite

Approved 2006
9.AJ.40

9 : SILICATES (Germanates)
A : Nesosilicates
J : Nesosilicates with BO3 triangles and/or B[4], Be[4] tetrahedra, cornersharing with SiO4
