* [[Agglutinated foraminifera|agglutinated]] (cemented foreign particles/grains)
: - with organic cement
: - with calcareous cement
* [http://en.wikipedia.org/wiki/Calcareous calcareous] from secreted [http://en.wikipedia.org/wiki/Calcium_carbonate calcium carbonate]  ([http://www.webmineral.com/java/Calcite.shtml calcite] or [http://www.webmineral.com/java/Aragonite.shtml aragonite])
: - [[Microgranular foraminifera|microgranular]]
: - [[Porcellaneous foraminifera|porcellaneous]]
