Stibiomicrolite (of Groat et al.)

This page is currently not sponsored. Click here to sponsor this page.



Colour:Light green to whiteHardness:4
Name:The name reflects its antimony (Latin "stibium") content and similarity to microlite.


The type sample for stibiomicrolite (Groat et al. 1987) and also the sample of Novák & Černý (1998) are now to be classified as oxystibiomicrolite.

Two compositions by Černý et al. (2004) are oxycalciomicrolite, and one is a calciomicrolite. The stibiomicrolite of Beurlen et al. (2005) is a zero valent dominant member of the microlite group.
