Welcome! The MAGMA website at Caltech is an online resource for the study of mantle melting and magma evolution. Look here for:

• MELTS, pMELTS and pHMELTS Users forum
  
• AlphaMELTS software download and information site
• Geodynamics: integration of melt formation and migration into mantle flow models
• Movies of phase diagrams for adiabatic decompression melting of peridotite and pyroxenite sources
• Applet for visualization of binary phase diagrams, tutorial and downloadable software for ternary version

• Source code, scripts and examples (currently only alphaMELTS and Adiabat_1ph related files are available but more will be added)
• ... plus a customized search page and links to other useful igneous petrology, geochmemisty, thermodynamics and computing sites (more coming soon).

New on this site: Adiabat_1ph 3 has been renamed alphaMELTS! Version 1.2 of alphaMELTS (equivalent to Adiabat_1ph 3.2) has been posted to the new alphaMELTS download site; older versions of Adiabat_1ph (up to and including 3.2) are available at the modified Adiabat_1ph site. Rhyolite-MELTS is available for Mac and Linux from the OFM website. Also, check out the new MELTS Facebook page.

Parts of this website are under construction and services may occasionally be interrupted during the next few weeks. We apologise for any inconvenience caused. As many of the pages have moved recently, please let us know if you find any errors or broken links. The Movies server is a beta and, as yet, has no documentation.

The MAGMA website, and the software & tools featured within are maintained by Paula Antoshechkina (e-mail username: psmith) and Paul Asimow (e-mail username: asimow). Please address any questions, comments or bug reports to them (e-mail domain: gps.caltech.edu). The site is hosted by the GPS Division at Caltech. The generation of this website, and the development, release, and maintenance of the Adiabat_1ph software is supported by the National Science Foundation through grant EAR-0838244. This ARRA-funded project is a collaboration between Caltech and OFM Research, to extend and improve the thermodynamic solution models (specifically garnet and pyroxenes) used by the MELTS family of algorithms. See xMELTS for more information.
