Abstract
Metalliferous deposits are common worldwide. Some have been derived from activities following industrial revolutions in various countries, albeit at somewhat differing times. Others can trace their antiquity much further. This appraisal seeks to consider the associated activities of sample collection protocols and selected analytical procedures and considers results, in a broad-based manner, from diverse geographic areas of our planet which exhibit a clearly defined recent or ancient industrial heritage.
