Limestone - A crucial and versatile industrial mineral commodity [ More info] Uses and availability of limestone and related commodities such as lime and portland cement. Hazards of limestone terranes due to erosion and sinkhole formation.
Microbial production of natural gas from coal and organic-rich shale [ More info] Explains how natural gas can be formed by microorganisms from geological materials, and how we plan to assess the potential value of this process for improving energy resources.
National Coal Resources Data System - US Coal Quality Database [ More info] Searchable database, the COALQUAL database, presented here and in the USGS Open-file Report 97-134, is a subset of samples contained in the NCRDS (National Coal Resources Data System) database, and contains coal quality data on each sample.
National Coal Resources Data System - US Coal Resource Database (USGCOAL) [ More info] Searchable database for locating information on coal resources by area, coalfield, coalbed, rank, quadrangle, source, years, or characteristics of thickness, overburden, and reliability.
Preliminary Assessment of Non-Fuel Mineral Resources of Afghanistan, 2007 [ More info] 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.
