Handbook of Exploration Geochemistry ; Volume 5
Content:
Geochemists, geologists, chemists, mathematicians, technicians and amateur prospectors alike will find this a practically oriented and comprehensive handbook for use in the field or office. It describes methodologies for assessing overburden in Arctic and temperate regions. Scientists can study the composition of bedrock by analyzing the overburden and ores found by the separation of the anomalies from the chemical background variation. This task is a very demanding one for previously glaciated terrain, where overburden consists totally of transported and mixed materials. It is possible to tra
