Inference of manganese nodule coverage from Sea Beam ...

Normal incidence reflectivity from a manganese nodule field was measured with a 12 kHz Sea Beam multibeam echo‐sounding system, aboard the R/V Thomas Washington and used to infer nodule coverage. A reflectivity map of the area was produced using the intensity of the specular return from each ping. The patchiness of the nodule coverage is evidenced by definite highs …

CARBONATITE DEPOSITS (MODEL 10; Singer, 1986a)

The geophysical signature of carbonatite complexes is variable (Hoover, 1992). In many complexes, concentrations of magnetic minerals produce positive magnetic anomalies. Similarly, concentrations of radioactive minerals cause pronounced radiometric anomalies associated with many carbonatite complexes. References

Manganese commonly is concentrated in soil, to form supergene deposits, by secondary manganese mineral growth. High manganese-iron ratios are characteristic of soil associated with these deposits. Abundances of other elements, except those of aluminum and potassium (in lithiophorite), are depleted by these processes.
