I refer especially to the chapters on mercury and helium. Both these elements have tantalised exploration geochemists for more than a generation as having all the attributes to detect deeply-buried mineralisation. The comprehensive reviews in this volume suggest that, in fact, neither has much VI Editor's foreword demonstrated use in mineral exploration. This type of negative data is just as useful as strongly positive information.

Notwithstanding the long gestation period of this volume, I am confident that it will nevertheless be not only a valuable guide for exploration geologists, but also the definitive source book on remotely-sensed exploration geochemical techniques for many years. Growth in demand for metals and fossil fuels prompted prospecting and exploration on a scale that has ensured that the endowment of such near- surface deposits has been discovered and evaluated in all but the most inaccessible places on Earth. The principle of using subtler non-visible clues in prospecting and exploration was taking shape in the early decades of the 20 th century.
Its practical value was demonstrated with the introduction of new instrumental techniques especially in chemical analysis that were able to furnish the appropriate data. This marks the origins of what we now call mineral exploration geochemistry.
It had gained widespread acceptance by mid-century and went on to account for countless new discoveries in a period of unprecedented growth in metal demand. Once again, however, we face the problem of exploration-technique exhaustion. Most deposits amenable to discovery by drainage geochemistry and soil geochemistry may well have been discovered. Innovations in analytical chemistry and geographic information systems improve data quality and data interpretability, but these represent refinements of an established technique rather than a new technique.
As early as the opening decades of the 20 th century the petroleum industry was searching for subsurface resources that had no conventional expression at surface. The minerals industry found itself in a similar position in the closing decades. So far, for prospecting, both industries have relied mainly on well-constructed geological models and remote sensing of the subsurface of target areas by geophysical techniques, most obviously seismic surveys in petroleum exploration, conductivity and gravity surveys in mineral exploration.

Alongside these, however, are thoroughly-researched and field- tested techniques for detecting, near the surface, geochemical expressions of subsurface petroleum reservoirs and mineral deposits. Gases play an important role in this geochemical remote sensing of the subsurface. Some are indicators of major or trace components of the subsurface resource: light hydrocarbons leak from petroleum reservoirs; sulphur gases are generated by sulphide mineral oxidation; and volatile mercury is released by sulphide oxidation.
