As shortages in the supply of mineral cotmnodities become more probable, there is an•increasing need for reliable and comparable reserve/resource data. It is therefore necessary to standardize the traditional classification procedure by quantifying the three basic criteria in resource evaluation: economic feasibility, geologic assurance, re…

This book is an attempt to provide a textbook in ore geology for second and third year undergraduates which, in these days of inflation, could be retailed at a reasonable price. The outline of the book follows fairly closly the undergraduate course in this subject at lecisester University which has evolved over the last twenty years. It assumes that…
Above--ground blomass and primary production values for 40 sites representing 22 virgin mire types which occur in the southern boreal vegetation zone in finland are presenterd. Eight ameliorated sites are included in the material. The biomass ranges between 360 - 20 270 g/m2 and is strongly correlated with stem volume on forested sites. Total annua…

India has finalized plans to begin a massive magnetite ore mining project which will use some of the most sophisticated mining and refining operations to date. The Kudremukh Iron Ore Project, a cooperative trade agreement between Iran and India, will allow India to tap her vast mineral reserves and export the end product to Iran. HE KUD…
