Monoclinic

Member of:

Hastingsite Root Name Group > Calcium Amphibole Subgroup > w(OH, F, Cl)-dominant Amphibole Group > Amphibole Supergroup

Name:

Named in 2009 by Marian V. Lupulescu, John Rakovan, M. Darby Dyer, George W. Robinson, and John M. Hughes for its chemical relationship to hastingsite.

Type Locality:

ⓘ Greenwood mine (Patterson mine), Town of Tuxedo, Orange County, New York, USA

The name fluoro-potassichastingsite has also been used for this mineral. The 2012 amphibole nomenclature follow the principle that the various prefixes to the root name are listed in order it occurs in the formula. The approved name for this mineral is consequently potassic-fluoro-hastingsite.

The hastingsite-group minerals are defined with 0.5 < ^A(Na+K+2Ca)<1.5 where Na or K is dominant and with the C position occupied by Mg or Fe²⁺ as dominant divalent ions and 0.5 < ^C(Al+Fe³⁺ +Cr+2Ti) < 1.5 where Fe³⁺ is dominant. W may contain (OH),F or Cl.

Fluoro-potassichastingsite is defined with:

A position: K dominant
C position: Fe dominant divalent ion
W position: F dominant
