Chesterton Soil Concretions: Ilmenite and Not Iron-Manganese Cementing Matrix

KENNETH L. WHITE 1

Dark reddish-brown spherules are common in soils of the Chesterton soil series of a high marine terrace in southern California. The spherules are concretionary in structure and are bound by ilmenite rather than by an iron-manganese complex. The spherules have been mislabeled both with respect to structure and mineralogy.
