Page vi - The application of a combination of disciplines into the hybrid science termed biogeochemistry has gained momentum in recent decades, bringing the benefit of research into the overlapping areas of geology, biology, and chemistry This report coalesces these technologies in a coherent interrelationship for application to mineral prospecting Theoretical concepts are presented, including the geochemical cycle through which chemical elements pass in the process of becoming plant nutrients, the physiological...

Page 73 - Garlio-like odor common to foliage owing to presence of selenium. Altitude: 4500 to 7500 feet. Occurrence: Best selenium-indicator plant in uranium districts of the Colorado Plateau because requirements and absorption of selenium are very high. Commonly absorbs several thousand parts per million of selenium and several hundred parts per million of molybdenum from ore bodies. Plot experiments suggest growth stimulated in vicinity of carnotite deposits by increased solubility of selenium and molybdenum...
