Geochemical data for the Pacheco stage tephra-fall deposits from Misti volcano, Arequipa, Peru
February 4, 2024
These data are derived from pumice and scoria from Pacheco stage (as defined by Harpel et al., 2021) tephra-fall deposits (TFD) emplaced between

To mix or not to mix: Details of magma storage, recharge, and remobilization during the Pacheco stage at Misti Volcano, Peru (≤21–2 ka) To mix or not to mix: Details of magma storage, recharge, and remobilization during the Pacheco stage at Misti Volcano, Peru (≤21–2 ka)
We investigate ten of the most recent tephra-fall deposits emplaced between ≤21–2 ka from the Pacheco stage of Misti volcano, Peru, to elucidate magma dynamics and explosive eruption triggers related to magma storage, recharge, and remobilization. Whole-rock, glass, and mineral textures and compositions indicate the presence of broadly felsic, intermediate, and mafic magmas in a...
