[meteorite-list] Looking for desert varnish

[Laurence Garvie]

I am studying the mineralogy and chemistry of desert varnish from the  
southwestern USA. I am eager to study similar varnish from deserts  
world-wide. The varnish that I am interested in forms on rocks from  
desert pavements and is typically dark black, sometimes shiny. Note,  
I am not particularly interested in the red varnish, which has a  
different mineralogy and chemistry from the black varnish.


So, does anyone have any meteorwrongs from known locations from  
Africa, Middle East, Mongolia?, or Australia that they are willing to  
part with. I do not need large samples, small pebbles or cobbles are  
big enough. Important though is a known location for the sample.

If anyone has samples they are willing to part with, then please  
email me privately.

Thank you in advance.

Laurence
