| Resumo |
Ferromanganese concretions from Grand Lake and Ship Harbour Lake in Nova Scotia and Mosque Lake in Ontario are most common in water 0.5 to 2 m deep. X-ray diffraction studies show the ferromanganese portions of the concretions to he amorphous. Petrographic and electron probe studies of the ferromanganese material reveal chemical banding of iron and manganese. Bulk chemical analyses indicate that the Fe:Mn ratios of concretions from different sites within a single lake are similar, whereas concretions from different lakes have characteristic Fe:Mn ratios. Trace element concs are different in different lakes and are generally several orders of magnitude less than those of oceanic nodules. |

Illustrations 3 and 4 are upper and lower surfaces of a larger concretion from the same lake (URI: hdl:10013/epic.46364.d001) Fig1b. Specimen 5 displays the upper surface of an unusual form of Grand Lake precipitate. Illustrations 6 and 7 exhibit the upper and lower surfaces of typical Grand Lake concretion (URI: hdl:10013/epic.46364.d002) Fig1c. Illustrations 8 and 9 show the upper and lower sides of a typical nodule from Mosque lake, Ontario (URI: hdl:10013/epic.46364.d003) Warnken, Robin R; Virden, William T; Moore, Carla J (1992): The NOAA and MMS Marine Minerals Bibliography.
