Moreover, a large number of codes have been developed [e.g., Wright and Doherty, 1970;Stormer and Nicholls, 1978;Woussen and Côté, 1987;Conrad, 1987;Holm, 1988Holm, , 1990Nielsen, 1988;Defant and Nielsen, 1990;Harnois, 1991;Benito and López-Ruiz, 1992;D'Orazio, 1993;Verma et al, 1998;Keskin, 2002;Spera and Bohrson, 2001] to help researchers in performing specific geochemical models. All these software allowed users to greatly speed up modeling of geochemical data, but some of them are designed for old MS-DOS operating systems and cause problems when loaded into modern MS Windows systems.…”
