  abstract = {{T}he breakup of supercontinents is accompanied by the emplacement of continental flood basalts and dike swarms, the origin of which is often attributed to mantle plumes. {H}owever, convection modeling has showed that the formation of supercontinents result in the warming of the sub-continental asthenospheric mantle ({SCAM}), which could also explain syn-breakup volcanism. {T}emperature variations during the formation then breakup of supercontinents are therefore fundamental to understand volcanism related to supercontinent cycles. {M}agmatic minerals record the thermal state of their magmatic sources. {H}ere we present a data mining analysis on the first global compilation of chemical information on magmatic rocks and minerals formed over the past 600 million years: a time period spanning the aggregation and breakup of {P}angea, the last supercontinent. {W}e show that following a period of increasingly hotter {M}grich magmatism with dominant tholeiitic affinity during the aggregation of {P}angea, lower-temperature minerals crystallized within {M}g-poorer magma with a dominant calc-alkaline affinity during {P}angea disassembly. {T}hese trends reflect temporal changes in global mantle climate and global plate tectonics in response to continental masses assembly and dispersal. {W}e also show that the final amalgamation of {P}angea at similar to 300 {M}yr led to a long period of lithospheric collapse and cooling until the major step of {P}angea disassembly started at similar to 125 {M}yr. {T}he geological control on the geosphere magma budget has implications on the oxidation state and temperature of the {E}arth's outer envelopes in the {P}hanerozoic and may have exerted indirect influence on the evolution of climate and life on {E}arth.},
