Note: Rock characterized by, consisting of, or producing concretions; concretions are hard, compact aggregates of mineral matter, subspherical or irregular in shape, formed by precipitation from water solution around a nucleus, such as a shell or bone, in a sedimentary or pyroclastic rock. Concretions are generally different from the rock in which they occur, and represent a concentration of some minor constituent of that rock. Concretionary stones include flint, chert, and nodules of impure limestone which sometimes occur in clay.

Additional Notes: |
|
| Chinese (traditional) ..... 以凝結物為特色的岩石，內含凝結物或用來製造凝結物。其凝結物質硬且緊密聚集礦物物質，幾近球形或不規則狀。凝結物由沈積岩或火成碎屑岩內核心（如殼或骨頭）周圍的水溶解沉澱物而成，通常不同於岩石，反而呈現岩石中某些次要成分之聚合。凝結石包括燧石、黑矽石及有時見於黏土內之不純石灰岩結節。 |
| Dutch ..... Gesteente dat zich kenmerkt door of bestaat uit concreties, of concreties voortbrengt. Concreties zijn harde, compacte aggregaten van minerale materie. Ze zijn subsferisch of onregelmatig van vorm en ontstaan door neerslag van in water opgeloste stoffen rond een kern, zoals een schelp of bot, in afzettingsgesteente of pyroklastisch gesteente. Concreties verschillen doorgaans van het gesteente waarin ze voorkomen. Ze vormen concentraties van een bestanddeel dat in kleine hoeveelheden voorkomt in dat gesteente. Soorten concreties zijn onder andere vuursteen, hoornkiezel en klompen onzuivere kalksteen die soms in klei voorkomen. |
| Spanish ..... Roca caracterizada por, consistente en o que produce concreciones. Las concreciones son agregados duros y compactos de materias minerales, de forma subesférica o irregular, formadas por precipitación de sustancias disueltas en agua en torno a un núcleo, tal como una concha o hueso, en una roca sedimentaria o piroclástica. Las concreciones son en general muy diferentes a la roca en la cual se presentan, y representan una concentración de un constituyente menor de esa roca. Las piedras con concreciones incluyen el pedernal, cuarzo y nódulos de caliza impura que a veces se encuentran en la arcilla.
