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.
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.
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.
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.
