Rhyolitic volcanoes and their products

A nine-day professional training course on rhyolitic volcanoes and their products for the exploration geology team (six geologists) of a company exploring in a poorly understood subaerial rhyolite-dominated volcanic succession.

Participants varied widely in experience and had no prior volcanology training. Two days of lectures covered:

(1) how eruptions of rhyolitic volcanoes work and what they produce

(2) the size, scale and architecture of rhyolitic volcanoes

(3) how to name and interpret common kinds of rhyolitic volcanic facies.

Practical training followed in the context of seven days fieldwork involving all the major exploration projects. Company geologists received detailed feedback and coaching on project areas they had mapped.
