Abstract

The three sites studied have had different histories of salt accumulation and display variable influence of groundwater, which is interpreted to have been forced to the surface during earthquakes. The clear accumulation of salts associated with fractures at the Spence deposit, and shifts in the isotopic composition of carbonate and sulfate in the fractures despite clear evidence of relatively recent removal of salts indicates that transfer from groundwater is an ongoing process. The interpretation that groundwaters can influence the isotopic composition of pedogenic calcrete and gypsum has important implications for previous studies that have not considered this mechanism.

Agradecimiento
We thank Richard Alcock of CAMIRO, and 26 company sponsors for their support throughout the project. The sponsors included Noranda Ltd., who generously provided the data from their geochemical surveys and drilling at the Tamarugal anomaly. We particularly wish to thank Garth Graves of Noranda, whose assistance and generosity made this study possible. Analyses of these soils were provided by John Gravel of Acme Laboratories (aqua regia) and Eric Hoffman of Actlabs (Enzyme Leach (TM)). Daniel Salinas is thanked for assistance in soil and groundwater sampling and Alexis Ramirez is thanked for his assistance with the groundwater sampling at Tamarugal. The samples from the Spence salar were collected with Neil O'Brien of Cominco Ltd., who also kindly provided the analyses. Wendy Abdi (University of Ottawa) is thanked for overseeing the stable isotope analyses. We thank two anonymous reviewers and Associate Editor Berry Lyons for their comments that improved the manuscript.
