A septarian concretion is a unique rock formation characterized by its striking cracked or geometric pattern. These formations are composed of a combination of minerals, such as #calcite, #aragonite, #barite, and sometimes #pyrite, encased in a hard outer layer of #limestone or #mudstone.

Do you miss the beach? I do too, so I brought a bit back with me.
