Abstract

A thin, dark brown rock varnish is described from ice-smoothed bedrock on the forefield of a glacier in North Norway. Glacier retreat rates indicate that the varnish has remained exposed subaerially at the surface for about twenty years, and its restricted occurrence suggests that it is not of biological origin but rather is essentially authigenic. Possible subglacial origins for associated iron and silica precipitates are also suggested
