文摘
- •
Clinopyroxene–melt partition coefficients (Di) are measured for trachy-phonolitic magmas.
- •
REE and Y incorporations are controlled by charge-balance mechanisms.
- •
Trace element systematics can be described by the lattice strain theory.
- •
An improved model for the prediction of DREE and DY has been developed.
- •
The model has been tested using compositions from the Campanian Ignimbrite eruption.
