>
> Dear Members of the list
>
> I have just had a vacation in the Chamonix Mt Blanc area of France where I
> saw some fantastic strained Xenoliths.
> They were seen in the area around the Couvercle refuge and are notable for
> a
> number of reasons.
>
> All seen showed the following:
> - Approximate 1:10 aspect ratio.
> - Consistent orientation.
> - The long axis is aligned parallel to the really nicely developed S
> fabric
> - Little or no alteration halo.
>
> In the region there are unstrained xenoliths which show a relatively
> consistent sizes and ranges of emplacement orientations.
>
> Does anyone know of any calculations of the strain implied by these
> xenoliths.

> Thanks
