Exempel på hur man kan använda ALUMINOUS i en mening

• The upper mantle is dominantly peridotite, composed primarily of variable proportions of the minerals olivine, clinopyroxene, orthopyroxene, and an aluminous phase.
• It occurs in association with crandallite and variscite in fractures in aluminous metamorphic rock, in hydrothermal regions and in phosphate rock deposits.
• The town is endowed with rich mineral resources like aluminous laterite ore, chromite, gold, niceliferous laterite, sand and gravel, guano, rock phosphate, limestone, and siliceous sand.
• It has been discovered that the volcanic ash that Romans employed in the mix for construction of harbor piers and sea walls contained phillipsite, and that an interaction with sea water actually causes crystalline aluminous tobermorite structures in the mortar to expand and strengthen, making the material substantially more durable than modern concrete.
• There are some cements such as the aluminous, derived from aluminous and lime materials, that are black (melanocratic).
• Containing compounds of silicon calculated as silica to the extent of more than 3% by weight of dry material, other than natural sand, zirconium silicate, calcined china clay, calcined aluminous fireclay, sillimanite, calcined or fused alumina, olivine; or.
• The formation of the hydrate from this mineral and from monocalcium aluminate represents the first stage of strength development in aluminous cements.
• As seawater percolated within the tiny cracks in the Roman concrete, it reacted with phillipsite naturally found in the volcanic rock and created aluminous tobermorite crystals.
• Hotsonite was discovered while investigating for aluminous metamorphic rocks in an abandoned sillimanite quarry in 1982.
• To the north, the southern peneplain straddles the Inini synclinorium, mainly composed of the Paramaca series, which corresponds to a series of micaschists, aluminous paragneisses and black quartzites whose total thickness is about 1 km.
• It shows most of the important reactions that govern the development of aluminous mineral assemblages from the prehnite-pumpellyite facies to the granulite facies, as well as the blueschist facies and eclogite facies at higher pressures and the contact hornfels facies at lower pressures.
• He also described the U-Th-Pb, Sm-Nd, and Rb-Sr isotopic systematics of mafic and ultramafic xenolithic rocks and associated megacrystic inclusions of aluminous augite and garnet, that occur in three alkalic volcanic suites: Kuandian in eastern Liaoning Province, Hanluoba in Hebei Province, and Minxi in western Fujian Province, China.
