From: Thermal evolution of Andean iron oxide–apatite (IOA) deposits as revealed by magnetite thermometry

Calculated temperatures and median concentrations of selected trace elements in magnetite from IOA deposits of the Chilean Iron Belt. (a) Temperatures calculated using the TMg-mag thermometer43. Uncertainties (error bars) are at ± 50 °C. (b) Titanium, V and Ga median concentrations determined by LA-ICP-MS, except for Los Colorados in which EMPA (Ti, V) and LA-ICP-MS (Ga) data were used.
