Hello all, I believe the subject of desert varnish came up last week. Coincidently, I just received my copy of Geotimes which contains an article on the subject. The link to the article follows: http://www.geotimes.org/current/NN_rocks.html?sid=8be9de0117ecc48d30ec6a4053 5fcfd0
The bottom line, from their article, is: "... when he and his colleagues analyzed the black, desert varnish from rocks in the Mojave Desert, they discovered three different kinds of D-amino acids that suggest the varnish is of biological origin.
