Member of:

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

Name:

The name katophorite was first used by W.C.Brøgger (1894) for an amphibole mineral that were found and described by him from three different localities in the Permian Oslo Region, Norway a) from a grorudite at Grussletten, Grorud, Oslo; b) from sølvbergite along the Kjose-Oklungen Railway, Vestfold and from a sølvbergite boulder found in Lågendalen, Vestfold.

The name is derived from the greek κατώφορος for moving down, in allusion to the alteration of the position of the optic Z-axis relative to the c-axis with a chemical variation toward arfvedsonite.

Katophorite was defined as the katophorite group mineral with Fe and Al as the dominant elements in the C position in the 1978 and 1997 amphibole nomenclature. The katophorite group was redefined in the 2012 amphibole nomenclature, renaming the Fe²⁺ and Al dominant member of the group ferro-katophorite.

The name katophorite is now used for the Mg and Al dominant member of the group, which was named magnesiokatophorite in the 1978 and 1997 amphibole nomenclature.
It was redefined according to the new nomenclature by Oberti et al. 2014 (IMA2013-140) based on a specimen from Jade Mine Tract, Kachin Province, Myanmar.

Type Locality:

ⓘ Hpakant-Tawmaw Jade Tract, Hpakant Township (Hpakan; Phakant; Phakan), Mohnyin District, Kachin State, Myanmar

NOTE: All localities and photos listed here under "katophorite" should be checked if they are to be assigned to katophorite according to the redefinition.
NOTE 2: The mineral originally designated by Brøgger (1894) as "katophorite" is now classified as ferro-katophorite according to the new amphibole classification.
