It is virtually impossible to discuss the geochemistry of lake sediments as a subject completely divorced from lake waters. Therefore, lake waters will be. Abstract. A regional lake sediment and lake water sampling program was completed for eastern Cape Breton Island in by the Geological Survey of Canada and Nova Scotia Department of Mines and Energy Joint Project under the Canada - Nova Scotia Co.
tion of regional lake sediment geochemistry to mineral exploration by Coker et al. () and Hornbrook (). Fresh insights on this topic from studies of geochemical stratigraphy in lake sediment cores are sum-marised, and some examples of recent applications of lake sediment geochemistry in mineral exploration for gold and base metals are.
REGIONAL GEOCHEMICAL DATA COMPILATION AND MAP PREPARATION, LABRADOR, CANADA 99 The approach we have taken is to only correct the Zn data for LOI using an empirical function that falls from a value of at 1% LOI, through at 4% LOI to at 12% by: A geochemical database of 21 lake-sediment samples, analysed for 53 elements by ICP-MS after aqua-regia digestion, has been created.
Statistical tests and plots of the combined data (in some cases, after the application of levelling functions) show that the disharmony that existed previously – between analyses that employed digestions of differing strengths – can be largely Author: Stephen Amor, Martin McCurdy, Robert Garrett.
