Characteristics of manganese oxide SEM image showed that the quartz sand had a relatively uniform and smooth surface (Fig. 1). The coated sand surfaces were apparently occupied by nascent manganese oxides formed during the coating process. The amount of manganese on the surface of MOCS was ca. 5.46 mg Mn/g sand.

Manganese can be found in toxic concentrations in landfill leachate, besides being one of the main contaminants from acid mine drainage. Column tests were performed in two groups of compacted soil samples to determine the manganese retardation factor. The sample groups presented slightly different soil compaction degrees and water contents.

Another media that converts soluble forms of iron and manganese to insoluble forms that can then be filtered is manganese greensand. Manganese greensand has been used for several decades and is formed from processed glauconite sand. The glauconite is synthetically coated with a thin layer of manganese dioxide, which gives the dark sand a ...

Manganese oxides (there are several manganese-bearing minerals that grow this way) precipitate out of hydrous solutions in veins separating rocks. This (or sometimes also branchingly grown inclusions within other crystals) is what the term "dendrite" means in geology.

The purple sand at Pfeiffer Beach is the result of manganese garnet deposits washing down onto the beach from neighboring hills. The streaks of purple are much more visible if you visit just after it has rained, which generally happens in winter and early spring in California. But you may find pockets of purple sand at other times as well.
