The significance of secondary iron and manganese oxides in geochemical exploration
Abstract
The significance of secondary iron and manganese oxides in geochemical exploration is suggested by their common occurrence as coatings or concretions and as discrete particles of colloidal dimensions in soils and stream sediments and by their strong scavenging of important ore metals from the weathering zone. Chemical fractionation techniques are available to partition secondary oxides and their associated metals into different mineral phases and chemical forms by partial selective extraction. A knowledge of the distribution of metals in various chemical combinations is valuable to geochemical exploration in providing a proper selection of sample medium and extraction procedure and in helping evaluate the significance of metal anomalies. Studies of secondary Fe and Mn oxides and their relationships to the geochemistry of heavy metals should be further strengthened.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
