Septarian concretion.

Carbonate concretions in clastic rocks and their septarian fracture fills act as 'time capsules', capturing the signatures of chemical and biological processes during diagenesis. However, many aspects of the formation of concretions and septarian fractures remain poorly understood, for although concretions occur in clastic rocks throughout the geological record, they are rarely documented in ...This Metaphysical Crystals item is sold by Elbfae.

Concretion. Concretions are masses of mineral matter embedded within rock layers, including limestone, sandstone, and shale.
