Production of this book has depended on generous financial support from sponsors of the Key Centre for Ore Deposit and Exploration Studies, in particular, the Tasmanian Department of «Mines, Aberfoyle Resources, ВНР Exploration, CRA Exploration, Geopeko, Pancontinental, Pasminco, RGC Exploration and Western Mining Corporation.

Although the material presented comes principally from the collections of J.McP and RLA. we made use of some thin-sections, hand specimens and photographs contributed by colleagues: Stephen Abborr, Guillermo Alvarado. David Cooke. Keith Corbea, Bruce Gemmell. Bruce Houghton, John Waters, Matthew While and Colin Wilson. We are further indebted tо Aberfoyle Resources and Pasminco for usc of many sample from drillcore stores at Hellyer and Rosebery.

The first draft was substantially revised after reviews by Stuart Bull and Ross Large (CODES); Fergus Fitzgerald (Pasminco Exploration), Malcolm Howells (British Geological Survey/, Noel White (ВНР) and Hiromitsu Yamagishi (Geological Survey of Hokkaido).

The production team included June Pongratz (design and desktop publishing), Jcancttc I lankin and Kirst)' Whalcy (typing!- Debbie Flardmg (draughting).

Volcanic activity can have a profound effect on the Earth's atmosphere and environment across many spatial and temporal scales. From being the source of most gases in the atmosphere over geologic time scales, to producing climate change, to threatening aviation, volcanic eruptions as well as non-eruptive volcanic gas and particle emissions provide a strong link between the lithosphere and the impact of the atmosphere on human activities.
