1. In p. 242 the ‘Methods’ section. ‘Field investigation was carried out during September and October, 2002’ was not right. This sentence should be changed as ‘Field investigation was carried out during September and October, 1999’. 2. In p. 243 the ‘Methods’ section. ‘All inorganic and stable isotope analyses were carried out at the activation lab in Lanzhou, China’ should changed as ‘All inorganic and stable isotope analyses were carried out at geochemical and hydrogeology laboratory of the British Geological Survey in Wallingford, UK’. 3. In p. 243 the ‘Methods’ section. ‘Two augur profiles were drilled by hand at Beitu’ should changed as ‘Two augur profiles were drilled by hand in the Baddan Taran desert’. 4.

Foundation of China (No.04AJL007)’ should changed as ‘The research receipt of a NERC award (1141.1005) for analysis of radiocarbon. The research is supported by the National Science Foundation of China (No. 40302031) and the Royal Society through its link scheme (PEK/0992/306)’. In p.249 the ‘Recharge to the aquifer’ section. ‘the regional effective annual rainfall (Reff) is 110 mm’ should to be changed as ‘the regional effective annual rainfall (Reff) is 89 mm’. In p.249 the ‘Recharge to the aquifer’ section. Table 3 should be changed as In p.249 the ‘Recharge to the aquifer’ section. ‘The estimation rate of recharge range from 1.55 to 1.64, with a mean value of 1.6 mm yr 1. This value represents about 1.5% of rainfall.’ should be changed as ‘The estimation rate of recharge range from 1.26 to 1.33, with a mean value of 1.3 mm yr 1. This value represents about 1.5% of rainfall’. In p.250 the ‘Conclusions’ section. ‘In our study, the estimation rate of recharge range from 1.55 to 1.64, with a mean value of 1.6 mm yr 1.’ should be changed as ‘In our study, the estimation rate of recharge range from 1.26 to 1.33, with a mean value of 1.3 mm yr 1.’
