Fig. 2: Compositional data of Antuco samples.
From: Long-term volcano evolution controlled by lateral collapse at Antuco volcano, southern Andes, Chile
Total alkali versus silica plot for bulk rock (a) and glass (b) showing compositions varying from basalt to dacite and trachyandesite. Letters represent basalt (B), basaltic andesite (BA), basaltic trachyandesite (BTA), andesite (A), trachyandesite (TA), trachyte (T) and dacite (D). c Time series of major oxide variations for bulk lava and pyroclast samples. Samples ANT-31B, C, and those from Late Antuco (LA) are from ref. 32.
