Description

In October 2010 a new mineral was published by M. S. RUMSEY , S. J. MILLS AND J. SPRATT in the Mineralogical Magacine Vol 74(5) with the name NATROPHARMACOALUMITE.

I found the type specimen some time ago in a largeFe-rich silicified boulder in the western area ofthe dumps.

The here offered specimen came from the same boulder and is co-type material and one of the best specimen I ever found.

Hundreds of lustrous and gemmy white microcrystals on matrix.
