Crystal Chemistry Points to an Eruption Trigger

In this lesson: Link the chemical signature with a modelled process and a next test.

Name: __________________________ Date: __________________

Read the story

Researchers found similar chemical signatures in small plagioclase crystals from Andean volcanoes, the University of Queensland reported on November 9.

Their modelling linked the pattern to hot magma entering a shallow reservoir. The team now wants to test whether it also appears in volcanoes in other settings.

Read and practise

1. Which process did the modelling link to the pattern?

   1. Hot magma entering a shallow reservoir
   2. Rain entering surface cracks
   3. The reservoir cooling without new magma

2. Why test volcanoes in other settings?

   1. To check whether the pattern appears beyond the Andean examples
   2. To assume the pattern applies everywhere without testing
   3. To restrict the interpretation permanently to one setting

Your turn

Describe the modelled process and the team’s planned comparison.
