Hi again...
Hope you don;t all get fed up with my Allende queries (you can see I got a
new one today... I'm like a small kid with a new toy!)
On examination under my binocular scope, I noticed a small patch of very
finely crystalline purplish coloured crystals, like a crust. now I am
presuming this is terrestrial in origin and possibly the start of the
equivalent of a desert varnish? As I understand it, manganese compounds
figure in the creation of desert varnishes and if my chemistry is not too
flawed manganese does have purplish salts.
I only wish I had a 'scope I could take pics thru then I could stop the
waffling and just point you all to a picture!
I suspect I have not described this as well as I could... if so can someone
please explain what I maybe seeing and what the process is?

thanks!
