About EckermanniteHide

Harry von Eckermann

Formula:

NaNa₂(Mg₄Al}Si₈O₂₂(OH)₂

The eckermannite group minerals are sodium amphiboles defined with ^A(Na+K+2Ca)> 0.5 apfu and 0.5 apfu < ^C(Al+Fe³⁺+2Ti) < 1.5 apfu with Al as the dominant element

Eckermannite is defined with

A position: Na dominant
C²⁺ position: Mg dominant
C³⁺ position: Al dominant
W position: (OH) dominant

Lustre:

Vitreous

Hardness:

5 - 6

Specific Gravity:

3.02 (Calculated)

Crystal System:

Monoclinic

Member of:

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

Name:

For (Claes Walter) Harry von Eckermann (5 November 1886, Stockholm, Sweden - 20 May 1969, Rönö, Sweden), industrialist, mineralogist and petrologist.

Type Locality:

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

Name first introduced for an amphibole from Norra Kärr, Sweden by Adamson (1942).
Redefined IMA in 2014 (IMA2013-136), according to the new IMA-approved nomenclature of amphiboles published in 2012 (Hawthorne et al., 2012).

NOTE: In the characterization of the holotype of eckermannite from Norra Kärr (Adamson, 1942), Li was not recognized (cf. Sundius 1945). Re-examination of the holotype material and of the original sample analyzed by Törnebohm (1906) confirmed that they both are actually fluoro-leakeite (Oberti et al. 2015). A new holotype for eckermannite, from the Jade Mine Tract, Myanmar, was designated by Oberti et al. (2015).

NOTE: All localities listed here under "eckermannite" should be checked if they are to be assigned to eckermannite according to the redefinition.

Eckermannite is to be expected in metabasites in the post-glaucophane high-P regime (Howe et al., 2018).
