Manganoan berthierine, Meyers Pass, New Zealand: occurrence in the prehnite-pumpellyite facies

D. S. Coombs, G. Zhao, D. R. Peacor
Published: 01 December 2000
Mineralogical Magazine (2000) 64 (6): 1037–1046.
...D. S. Coombs; G. Zhao; D. R. Peacor Abstract Manganoan berthierine, sometimes only a few layers thick, is preserved interlayered with manganoan chlorite (chamosite) in small recrystallized patches in cherty metapelagites matamorphosed in the prehnite-pumpellyite facies at Meyers Pass, Torlesse...

Fields of berthierine and chlorite after Jiang et al. (1992, Fig. 11) showing tetrahedral site occupancies normalized to 20 total octahedral plus tetrahedral cations plotted against the ratio (Fe,Mn)/(Fe,Mn,Mg). Open circles A, D: EMP analyses of coarse-grained ‘chlorite’ in OU 62096, 62097, respectively. B, C: AEM analyses of chlorite-rich and berthierine-rich chlorite-berthierine packets in OU 62096. E, F: AEM analyses of chlorite and of berthierine-rich chlorite-berthierine packet in OU 62097. Dashed lines show extension of the berthierine field to accommodate the manganoan berthierine analyses.
