Labradorite crystals were reacted with a 0.01 N HC1--H 2 16 O solution to produce an 1000 Angstrom-thick leached layer on the mineral surface. These crystals were then placed in a similar acid solution (0.01 N HC1) containing H 2 18 O for varying periods of time. After this reaction we observe that 18 O infiltrates the leached layer to depths of 1000 Angstroms in 3 days, and cannot be removed by heating of the mineral to 120°C, or by subjecting the sample to vacuum for several hours. This evidence suggests that most of the exchange was at silanol and siloxane groups in the leached layer, and not as loosely sorbed molecular water.
