- •
We present a set of lava compositions spanning the 2012–13 Tolbachik fissure eruption.
- •
We document a major compositional change after the first three days of eruption.
- •
From the mid December until the end of eruption lava compositions remained constant.
- •
High alumina basaltic trachyandesites with high alkalis and Ti content were erupted.
- •
Petrological modeling shows that high-Al 1975–6 and new lavas are genetically related.
