Frottage connection as the first stage of a new painting

This frottage taken at Mungo consists of graphite and red chalk is the first layer for a painting. In this underpainting the red chalk is similar to part of the geology known as the Gol gol formation above which the clay and sand of the dune formed. The red oxide-like pigment of the soil blown onto the dune by Westerlies gives the dune its pink colour as it gradually seeped into the porous sand.

I try to mimic aspects of the way the landscape formed by incorporating dry pigment and stained and frottage traces on paper into layers of paint.
