Arc Basalt Simulator (ABS) is a petrologic and geochemical simulation program for basalt to high-Mg andesite genesis in and above a subduction zone. ABS consists of three different calculation modules: (a) slab dehydration and melting along an appropriate subduction zone P-T path, (b) reaction of mantle peridotite with slab-derived melt or hydrous fluid migrating through the mantle wedge, and (c) melting of mantle wedge peridotite due to fluxing by this liquid. ABS is intended to be easy to use, requiring only a PC or Mac that can run Microsoft Excel. The download includes two files, the macro-enabled spreadsheet (.xlsm) and the tutorial (.pdf).
