New Zealand Geological Survey, Lower Hutt, New Zealand.

Summary: Sepiolite found as a minor constituent of dolomitie marble bordering tremolite rock from the southern contact zone of the Quérigut granite is briefly described and optical data are presented. A possible paragenesis, following on break-down of the tremolite under the action of carbon dioxide, is suggested.
