This report is the result of an extensive literature search to determine the state-of-the-knowledge regarding environmental impacts from quarrying carbonate rocks in karst formations to better use of karst resources in sustainable ways.
Estimates of known and undiscovered copper resources total nearly 60 million metric tons of copper. Iron resources in known deposits total 2200 million metric tons of ore. Twenty mineralized areas meriting further study were identified.
Links to Spectroscopy Lab projects to identify and map materials through spectroscopic remote sensing (imaging spectroscopy, hyperspectral imaging, imaging spectrometry, ultraspectral imaging, etc) on the Earth and in space.
Links to mineral statistics from annual Mineral Yearbooks for each state in the United States and Puerto Rico, with contacts for further information, and means to apply for e-mail subscription service for regular updates.
Shows where important mineral resources are located in Afghanistan, the type of deposits there, the commodities that are present, and describes the data available to support further exploration and exploitation of these resources.
Describes organizational process and field study used to estimate production capacity (mostly by artisanal miners) in the parts of the country likely to contain diamonds. We estimate a production capacity of 600,000 carats per year.
Presentation describing uses of rare earth elements, why they are important, where they occur and are produced, and aspects of the economics of production and consumption with emphasis on sites that might be developed for production.
