Chiastolite Crystal section

Ref: Chiastolite

Chiastolite is a variety of Andalusite (An Aluminium Silicate). This (average 20-25mm) specimen, from Zimbabwe, exhibits the characteristic 'cruciform' pattern in cross-section due to carbonaceous inclusions.
Andalusite has an orthorhombic prismatic crystal form resulting in an almost square cross-section. It is associated with sillimanite and kyanite and occurs in slates and pelitic schists. Also found in Australia, Brazil and the USA.
