Summary

edit
Description
English: This visually-intriguing rock is composed of multiple small to medium-sized, subspherical ironstone nodules (= iron oxide rock). They have become cemented together by a crust of the same iron oxide material. This material could also be called mammillary ironstone. Provenance: modern fluvial gravel bar in Ohio; mammillary ironstone like this supposedly occurs at the Mississippian-Pennsylvanian unconformity in parts of Ohio
