(1) Subtidal lithologies contain peloids, ostracodes, bivalves, gastropods and oncoids (with less common benthic foraminifera and calcareous algae).(2) The unit consists of limestone or calcareous mudstone and was deposited in a fully marine environment.(3) Zone 5 is characterized by deep-shelf, pro-deltaic, and shelf edge settings below storm wave base and generally lacking benthic calcareous algae.(4) This species grows poorly on calcareous soils, but when some of its roots are exposed to distilled water containing Al, its growth is improved.(5) Bivalves are characterized by a pair of calcareous shells, or valves, held together with an elastic hinge ligament.(6) Fritted iron can be used on acid soils, but it isn't suitable for use on alkaline or calcareous soils (with calcium carbonate).(7) As coccolith content increases the calcareous mudstone passes transitionally to a coccolith limestone.(8) It consists of phyllites, calcareous sandstones and limestone conglomerates that are boudinaged and folded.(9) The fungus can thrive in calcareous clay loam soils with a pH range of 7.0 to 8.5.(10) The ecology of different Ca physiotypes is thought to reflect their ability to utilize Ca as an osmoticum in primarily xerophytic, calcareous environments.(11) Granite rock is pretty much pH balanced, but most limestone or calcareous rocks will cause the water pH to go up or sour.(12) Kidney stones are broadly categorised into calcareous (calcium containing) stones, which are radio-opaque, and non-calcareous stones.(13) It forms a mosaic of various habitats from woodland and ponds, to herb-rich calcareous grassland, resulting in a rich bio-reservoir of flora and fauna.(14) These prairies, like the Black Belt, have rich soils derived from calcareous bedrock.(15) Because of their ability to secrete calcium carbonate, calcareous red algae have a better Phanerozoic fossil record than many other groups of algal protists.(16) Within the valley, the upland soils have been formed almost exclusively from limestone and calcareous shales.
