A geochemical investigation of the Sara Sara volcano (Peru): a Pleistocene edifice of the northern termination of the Andean Central Volcanic Zone

Chaptal et al., 2025. Lithos 518. doi:10.1016/j.lithos.2025.108282

• Sara Sara is the northernmost volcano in the peruvian CVZ.
• The Sara Sara main edifice is surrounded by some monogenic volcanoes.
• Sara Sara samples are dacitic and rhyolitic and monogenetic volcanoes are andesitic.
• Trace elements and isotope ratios indicate upper crustal AFC in a Mesozoic basement.
• Andesitic compositions imply deep crustal partial melting with residual garnet/rutile.
