American Heritage® Dictionary of the English Language, Fourth Edition
- adj. Of, containing, resembling, or derived from sediment.
- adj. Geology Of or relating to rocks formed by the deposition of sediment.
Century Dictionary and Cyclopedia
- In geology, formed by deposition of materials previously held in suspension by water: nearly synonymous with aqueous. A rock is massive when it has no structure indicating an aqueous origin; it is sedimentary when its appearance indicates that it is made up of the detritus of other rocks, eroded and carried away by watery currents, to be deposited in another place. All sedimentary rocks are made up of the fragments of the original crust of the earth, of eruptive materials which have come up through this crust from below, or of other sedimentary beds which, having been deposited, have again in their turn been subjected to erosion and redeposition. It is in sedimentary rocks that organic remains are found; in the original crust of the earth, or in volcanic materials, traces of life could not be expected to occur.

- adj. Of or pertaining to sediment; formed by sediment; containing matter that has subsided.
- adj. produced by the action of water
- adj. resembling or containing or formed by the accumulation of sediment
- From Latin sedere, to sit. (Wiktionary)
“The column is deposited only in sedimentary environments, where conditions favor the accumulation of sediments.”
“Fossils preserved in sedimentary rocks will display that era's primary forms, reflective of that era's ecology and life's adaptations to best exploit it.”
“But today oil companies are capable of drilling only as deep as six miles, and this in sedimentary rock; in igneous and metamorphic rock, drill bits have so far penetrated only two miles.”
“However, since they were mounting the massive original fossils (essentially, the original bones cast in sedimentary rock) rather than the lightweight polyester and fiberglass castings they use nowadays, the completed skeleton was too heavy to be supported in it's correct horizontal stance by the relatively flimsy iron armature it was mounted on.”
“The research work is based on the study of samples obtained in sedimentary bowls from the south of Spain to Turkey.”
“The finding broadens the known geographic reach of archaea during this time period, adding proof that the ancient organisms existed both in sedimentary environments and in subsurface hydrothermal settings.”
“This suggests that the 62-million year cyclicity originates from long-term changes in sedimentary depositional and erosional regimes, and raises the strong possibility that it is not a biological signal but a sampling signal.”
“Alternatively, rifting, collisions between land masses, and other tectonic forces can free the mature oil and gas from deep within sedimentary basins and then trap these organic fluids in reservoirs before they escape to the earth’s surface.”
“The oil is trapped in minuscule cells of porous subsurface rocks in so-called sedimentary basins.”
“In the span of millions of years, the growing weight of sediments causes the deeper layers to compact and gradually turn into rocks, called sedimentary rocks.”
