Melanosome (geology)

In geology, a melanosome is a dark,[1] mafic mineral band formed in migmatite which is melting into a eutaxitic texture ; often, this leads to the formation of granite. The melanosomes form bands with leucosomes, and in that context may be described as schlieren or migmatitic.

For the biological organelle involved in skin pigmentation, see melanosome.
