A low-charge corrensite, i.e., a regular 1:1 interstratified smectite/chlorite was found in veins and fissures of an extensively fractured dolomite south of Perth, Ontario, Canada. Total chemical analysis indicated that the mineral was trioctahedral, having a structural formula corresponding to:

(Ca0.17)(Mg7.36Al0.90Fe3+ 0.45Fe2+ 0.42)VI(Si6.06Al1.94)IVO20(OH)10.

The coefficient of variation (CV) of the d(00l) spacings calculated for the mineral from X-ray powder diffraction data was 0.42, well below the maximum recommended value for corrensite, 0.75. The corrensite coexists with phlogopite, which is present as small (~0.5 mm) crystals throughout the rock and locally as large (~5 cm) crystals in pegmatitic veins. Microscopic observatiofls of large phlogopite crystals partially altered to corrensite suggest that corrensite formed at the expense of phlogopite by hydrothermal alteration.

Résumé

Résumé

Une corrensite, minéral interstratifié régulier 1:1 smectite/chlorite, a été trouvée dans les veines et les fissures d'un affleurement dolomitique très fortement fragmenté au sud de Perth, Ontario, Canada. L'analyse chimique totale a montré que le minéral était trioctaédrique avec une formule structurale correspondant à:

(Ca0.17)(Mg7.36Al0.90Fe3+ 0.45Fe2+ 0.42)VI(Si6.06Al1.94)IVO20(OH)10.

Le coefficient de variation (CV) des espacements d(00l) calculé pour le minéral à partir des données de RX était de 0,42, soit bien en deça de la limite recommandée, 0,7 5. La corrensite coexiste avec la phlogopite qui est présente sous forme de petits cristaux (~0,5 mm) dans tout l'affleurement et aussi sous forme de grands cristaux (~5 cm) dans des veines de pegmatite. Un examen microscopique de plusieurs grands cristaux de phlogopite partiellement altérés en corrensite a suggéré que celle-ci est formée aux dépens de la phlogopite par altération hydrothermale.
