Manganese (Inventory)/Dendrite
From LagWiki
The Dendite field of the Manganese section should be used to record any appearance of manganese dendrites.
Manganese dendrites appear most often as tiny, scattered, black or dark purple dots on calcite or bedrock, and especially on calcite coatings over bedrock. When fully formed, they can form dark, fractal, fern-like shapes. The size can vary greatly from tiny specks to larger organized areas. Examine exposed bedrock and calcite, especially coatings on bedrock for the tell-tale dark dots which indicate manganese dendrites.
