Volcanoes and their products
A four-day professional training course on volcanoes and their products for the entire exploration geology team (25 geologists) of a company operating in diverse volcanic successions that host epithermal and porphyry deposits.
Participants varied widely in experience and most had no prior volcanology training.
Lectures covered eruption styles on land and under water, the characteristics of the products of eruptions, different kinds of volcanoes, the effects of hydrothermal alteration on volcanic rocks, and breccias in mineralised volcanic successions.
A third of the course was devoted to practical exercises conducted on natural exposures close to the venue. These exercises focussed on how to name, describe, record and interpret volcanic and other facies.
