Reddish-Brown Banded Rock Specimen - Geological Sample for Study #3905220 (License: Personal Use)

This irregularly shaped rock displays prominent banding of reddish-brown and gray minerals, suggesting possible foliation from metamorphism or crystallization layering in an igneous setting. Its rough, unpolished surface reveals visible grain boundaries and minor fractures, indicating minimal weathering and likely recent collection or preparation. The texture appears medium- to coarse-grained, consistent with rocks like gneiss or granite.
