I would have to go back to the thinnies to check, but as I remember it, the
lawsonite was isolated in side the feldspar. Of course always in the 3rd
dimension there could be a connection to quartz but I doubt it. So if this
was so, you could accept a contribution fom the strain energy resulting fom
the dislocation density. What did you think of Wintsch's attempts to
quantify it for coesite? I am sure Bob will not mind if you speak freely. I
always thought he was onto something there and so I am prejudiced in his
favour. Nothing seems to have come of it over the intervening years though.
Cheers
