Re: Preferred orientation and clay minerals

Hi Armel,
I am sure you will not be satisfied by this answer, but my solution to
this problem is : USE transmission geometry. We have been doing it for
years getting nice results for kaolinites, micas, vermiculites and
smectites, not to
speak of some organic plates. No need to add -osils (what's that, BTW).

P.S. I am not adding the type of diffractometer, but if you wish I can
scan a sample for you ....
