Black sand in North Carolina primarily comes from the weathering and erosion of minerals such as magnetite and ilmenite found in the region's geology. These minerals are often concentrated in certain areas, particularly along the coast and in riverbeds, where they accumulate due to their higher density. The presence of black sand is also linked to historical volcanic activity and the breakdown of certain rock types over time. Additionally, human activities like mining can expose and concentrate these dark minerals in the environment.
