Results 1 - 7 of 7 listed alphabetically [list by similarity]
PDF A methodology for conducting national-scale alluvial diamond resource potential and production capacity assessments, with a focus on artisanal mining [More info]
Geologic evidence, combined with geographical data and analyized through a geographic information system allows us to compare production statistics with likely resource estimates.
PDF Biochar for soil fertility and natural carbon sequestration [More info]
Explains what biochar is and how it is formed, its potential use in both fertilizer and carbon sequestration, and some of the research questions remaining to be addressed before we can utilize it fully in practical ways.
Geochemical sediment analysis procedures [More info]
Manual of chemical sediment analysis using Coulometer and CHN Analyzers to measure carbon content, spectrometric analysis for biogenic silica, and radiochemistry to measure isotopes. Includes techniques,sample preparation, and safety procedures.
PDF 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.
PDF Selenium and stable isotopes of carbon and nitrogen in the benthic clam Corbula amurensis from Northern San Francisco Bay, California: May 1995-February 2010 [More info]
Monthly selenium concentration in this keystone species shows strong spatial and seasonal variation in a five-year series of analyses.
PDF The concept of geologic carbon sequestration [More info]
Explains securing carbon dioxide in deep geologic formations to prevent its release to the atmosphere and contribution to global warming as a greenhouse gas.
PDF Thermal Properties of Methane Gas Hydrates [More info]
This unusual form of hydrocarbons can alter the thermal properties of host sediments; the analysis presented here helps us understand how those sediments might behave under natural or human-induced changes in the environment.
