Further to Helena Jaeschke's recommendation of a paper by Caitlin
O'Grady on manganese dioxide (MnO2) accretions (see Conservation
DistList Instance: 20:31 Saturday, December 9, 2006), you might also
find it helpful to consult the literature review by O'Grady in
Reviews in Conservation 6 (2005): "The occurrence of rock varnish on
stone and ceramic artifacts". She addresses authentication and
reviews relevant research. See:

    O'Grady, C.,
    "The occurrence of rock varnish on stone and ceramic artifacts"
     Reviews in Conservation 6-2005-31-38.
