Lithogeochemistry should be considered as part of a loop which starts with sound lithological, mineralogical, and structural observations, followed by petrography and geochemistry to provide a quantitative link to the field observations, with results that can be plotted on a map or drill log. Once the connection is made between field-petrographic observations and geochemical data, the confidence level is increased with respect to understanding the geological and mineralogical relationships in the field.
