About SchorlomiteHide

Formula:

Ca₃Ti₂(SiO₄)(Fe³⁺O₄)₂

Colour:

Grayish black, black, may be tarnished blue; deep reddish brown

Lustre:

Sub-Metallic

Hardness:

7 - 7½

Specific Gravity:

3.862

Crystal System:

Isometric

Member of:

Schorlomite Group > Garnet Supergroup

Name:

For its visual resemblance to schorl

Type Locality:

ⓘ Magnet Cove, Hot Spring County, Arkansas, USA

Garnet Group. Compare UM1982-16-SiO:AlCaFeTi and Morimotoite.

Much of the recent material labelled "schorlomite" is mislabeled and is, strictly speaking, Ti-bearing andradite/"melanite".
