Formula:

K1.5-x(Ca,Y,REE)5(Si6O15)(Si2O7)(OH,F)2 · yH2O

Colour:

Pink, red-brown, raspberry-red

Specific Gravity:

2.84 - 2.93

Name:

Named by Waldemar T. Schaller in honor of Dr. Hugh Dinsmore Miser [December 18, 1884 Pea Ridge, Arkansas, USA - August 1, 1969 Washington, DC, USA], geologist with the U.S. Geological Survey. This was a renaming of the inappropriately named natroxonotlite.

Structure was determined on Kipawa specimen.
