Water availability controls crustal melting temperatures
Although the capacity for water to lower the solidus during crustal melting is well recognised,
a modern consensus is that most granitic magmas are generated under fluid-absent melting …

An extended calibration of the olivine–spinel aluminum exchange thermometer: Application to the melting conditions and mantle lithologies of large igneous provinces
The application of the olivine–spinel aluminum exchange thermometer to natural samples is
limited by the restricted experimental data set on which it was calibrated. Here, we present a …
