Investigations of base metal and gold biogeochemical anomalies in the Mabel Lake area, southern British Columbia (NTS 82L09 and 10), Geological Survey Canada Open File, 6147, CD-ROM. 

Biogeochemical analysis of leaves of trees over the Pollard oil field, Alabama, indicates anomalous concentrations of Mn. Correlation analysis reveals a statistically significant relationship between biogeochemical Mn anomalies and producing wells. 

The identification of biogeochemical consequences of carbon, nitrogen, sulfnr, oxygen and other biophilic elements incorporation into biomass is recognized as an isotope fractionation or anomaly. When an element exists as a mixture of stable isotopes, as in the case of C, H, S, N, and 0, biochemical and chemical transformations... 

This section describes and discusses lanthanide distributions in the oceans and the biogeochemical and physical processes responsible for these distributions. Three interrelated subjects will be developed. These are (a) profiles of lanthanide concentrations in the water column and their variations within and between ocean basins, (b) the redox geochemistry of Ce as revealed by vertical and horizontal variations in the Ce anomaly and (c) the inter-oceanic mass fractionation of the strictly trivalent lanthanides.
