Summary: | The development of a comprehensive chemical model for exploration geochemistry requires a thorough understanding of oxide zone geochemistry. Furthermore, the same kinds of chemical considerations brought to bear are equally applicable to the dispersion of metallic pollutants from other sources in surface or near-surface environments. The aim here is not comprehensive coverage, although the main chemical aspects of oxide zone development and associated mineral formation have been addressed. The author develops certain topics of his own interest and highlights deficiencies in present knowledge. Annotation copyrighted by Book News, Inc., Portland, OR
