Abstract: Rock varnish dating method is a new chronologic method which has been widely used in dating the Quaternary deposits. A cation-leaching curve of rock varnish from the boundary area between Gansu Province and Xinjiang Region,Western China,is established in this study. In this paper the ages of middle-late Quaternary deposits and fault activity is also discussed from the varnish dating data.
