Exempel på hur man kan använda SEDIMENTARY i en mening

• Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.
• It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks.
• Kyanite is a typically blue aluminosilicate mineral, found in aluminium-rich metamorphic pegmatites and sedimentary rock.
• Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock.
• Conventional reserves of petroleum are primarily recovered by drilling, which is done after a study of the relevant structural geology, analysis of the sedimentary basin, and characterization of the petroleum reservoir.
• Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone.
• Slate is a fine-grained, foliated, homogeneous, metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade, regional metamorphism.
• Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced.
• Bryce is distinctive due to geological structures called hoodoos, formed by frost weathering and stream erosion of the river and lake bed sedimentary rock.
• It occurs as a common accessory mineral in igneous rocks (as primary crystallization products), in metamorphic rocks and as detrital grains in sedimentary rocks.
• A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, fault or tectonic breccia, igneous breccia, impact breccia, and hydrothermal breccia.
• Methane clathrates are common constituents of the shallow marine geosphere and they occur in deep sedimentary structures and form outcrops on the ocean floor.
• Situated within the Central Queensland Sandstone Belt, and straddling the Great Dividing Range, Carnarvon National Park preserves and presents significant elements of Queensland's geological history including two sedimentary basins, the Bowen and the Surat, and the Buckland Volcanic Province.
• Banded iron formations (BIFs; also called banded ironstone formations) are distinctive units of sedimentary rock consisting of alternating layers of iron oxides and iron-poor chert.
• It is mostly found in sedimentary rocks, often associated with the minerals gypsum, anhydrite, and halite.
• For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification.
• This community lives in or near marine or freshwater sedimentary environments, from tidal pools along the foreshore, out to the continental shelf, and then down to the abyssal depths.
• Galena Group, a sedimentary sequence of Ordovician limestone that was deposited atop the Decorah Shale.
• Covering most of the island, the coastal sedimentary plateau is a succession of highly eroded sedimentary peaks which are part of the Franklinian Shield with an extension of the Canadian Shield (Precambrian igneous and metamorphic rocks) in the island's southeastern corner.
• Weathering is a crucial part of the rock cycle; sedimentary rock, the product of weathered rock, covers 66% of the Earth's continents and much of the ocean floor.
