英文摘要	Modern atmospheric deposition along a west-east transect in the Atacama Desert, Chile, was collected to constrain the meteoric Cl-36/Cl ratio and Cl-36 deposition flux. The Cl-36 deposition flux had a threefold change, from 3.62(+/- 0.18) to 11.6(+/- 0.2) atoms m(-2) s(-1), going from the coast to the high Andes. The Cl-36 deposition was mainly as dry deposition, and the magnitude and differences between sites were attributed to stratosphere-troposphere transport and chloride deficits by acid displacement, respectively. The meteoric Cl-36/Cl ratios varied greatly from 31.5(+/- 1.1) x 10(-15) to 247(+/- 10) x 10(-15), which was attributed to local inputs of oceanic chloride near the coast or chloride minerals entrained from nearby salt playas. This study presented refined estimates of the Cl-36 deposition flux and meteoric Cl-36/Cl ratio in a desert region in southern tropical zone. The data set will provide a baseline for using natural Cl-36 abundances to date salt accumulation in the Atacama.
