WEBCoal balls often form in acidic peats, or when seawater permeates the compressed plant matter. The carbonate forms a hardened ball that resists compression throughout burial, thereby preserving the plant remains in exceptional detail; even cellular details can be retained. Such structures can be studied using a range of techniques.
