About AstrophylliteHide

Formula:

K₂NaFe²⁺₇Ti₂Si₈O₂₆(OH)₄F

Colour:

Bronze-yellow, golden yellow, brown to reddish brown

Lustre:

Greasy, Pearly, Sub-Metallic

Hardness:

3

Specific Gravity:

3.2 - 3.4

Crystal System:

Triclinic

Member of:

Astrophyllite Group > Astrophyllite Supergroup

Name:

From the Greek άστρον ("astron") for "star" and φύλλον ("phyllon") for "leaf", in allusion to its habit of starburst-like sprays and micaceous cleavage. It was named by the German chemist, geologist and mineralogist Carl Johan August Theodor Scheerer (1813-1875) in 1854.

Type Locality:

ⓘ Låven, Larvik, Vestfold, Norway

Astrophyllite Group.
The mineral was first found in 1844 by the Norwegian mineralogist Paul Christian Weibye (1819-1865) and later described by him, in 1848, as a brown, micaceous mineral ("brauner Glimmer") from Låven (formerly Lamöskjär), Langesundsfjorden, Norway (Weibye 1848). Later Scheerer (1854) described it under the name astrophyllite. Brøgger (1890) described in detail the crystallographic and optical properties as well as its chemistry.
