In Australia, the same tree is a rapid grower to double the California height. Fortunately, however, natural radiation is never as high as that encountered at Hiroshima in and levels normally encountered are therefore seldom sufficient to produce an obvious stimulatory effect on vegetation.

If recoverable gold occurs in the rape turnip, obviously the next step is to genetically modify it to absorb even more gold, sew the seeds all over California and do our prospectinng with a lawnmower. The theory behind such colour changes is interesting and may have bearing on mineral exploration.

Definition of geobotanical prospecting

As for the Northern Regions, names such as Coppermine in the Central Arctic and the Copper River in southwest Alaska are common-place, while the Canadian Shield is again recognized for both its variety and its mineral richness – not merely copper, but Gold, Silver, Tin, Lead and Zinc.

In the early nineteenth century, the Russian geologist, Karpinsky observed that different plants or plant communities could be indicators of rock formations and that the characteristics of the plants of an area could be used to decipher the geology of the area.

The origins of geobotanical prospecting in China go back to the preoccupation with the nature of different types of soil and their suitability for crops. It is perhaps not that well known just how pure some of the copper deposits from certain areas of North America were – so pure in fact that they could be directly hammered into sheets.
