resembling or containing or formed by the accumulation of sediment; "sedimentary deposits
Pertaining to sediment Solid fragmental material transported and deposited by wind, water or ice, chemically precipitated from solution, or secreted by organisms, and that forms in layers in loose unconsolidated form
- a rock that is formed by the deposition of sediments, fragment size is not implied nor is composition; examples, limestone, sandstone, siltstone, conglomerate
rock rock formed by the accumulation and cementing together of deposits laid down by water, wind, or ice - for example, limestone, shale, and sandstone Sedimentary rocks cover more than two-thirds of the Earth's surface
A type of rock formed when rock or mineral fragments are compressed into solid layers
(a) Pertaining to or containing sediment (b) Formed by the deposition of sediment, or pertaining to the process of sedimentation (c) A sedimentary rock
rock formed of sediment, (conglomerate, sandstone, and shales formed of fragments of other rock transported from their sources and deposited in water) or by precipitation ( rock salt and gypsum), or organisms ( limestone)
A rock formed through the accumulation of sediment The sediment may be weathered materials from other sedimentary, igneous or metamorphic rocks transported by wind or water and deposited on land, by rivers or in the sea One sedimentary rock, limestone may be formed by the accumulation of shells or shell debris, or rarely by direct chemical precipitation from the sea-water The sediment may be cemented to varying degrees
rocks formed from material derived from pre-existing rocks by processes of denudation, together with material of organic origin, relating to rocks formed by the deposition of sediment - BACK>>
rocks formed by cemented particles or chemical reactions in or near water SHALE sedimentary rock that splits easily into layers SOFT not hard or firm
Type of rock, commonly formed in layers by the deposition of silty materials onto the sea bed
Rocks formed by the accumulation of sediments (sandstone, shale) or the remains of products of animals or plants (limestone, coal)
Sedimentary rocks are formed from sediment left by water, ice, or wind. made of the solid substances that settle at the bottom of the sea, rivers, lakes etc
Descriptive term for rock formed of sediment; clastic rocks, conglomerate, sandstone, shales, rocks formed by precipitation from solution as salt, gypsum, or from secretions of organisms as are most limestones
rock formed of fragments of other rocks that have been moved from its source and deposited in water, such as: shale, sandstone, or limestone Sedimentary rock often has a layered appearance
Descriptive term for rocks formed of sediment This includes clastic rocks such as conglomerate, sandstone, and shale formed from fragments of other rocks transported by the action of wind or water from their source The term also includes rocks formed by inorganic precipitation from solution such as gypsum and limestone, or from secretions from living organisms as in the case of some limestone
Of or pertaining to sediment; formed by sediment; containing matter that has subsided
One of the three types of rock It is a rock that is formed from minerals that are cemented together because of pressure More info -
Of or relating to rocks formed from sediment (fine solids that settle to the bottom of a liquid) or from fragments of other rocks deposited in water
One of the three basic categories into which rocks can be classified, of which the other two are igneous and metamorphic Sedimentary rocks are formed by the compaction and cementation of sediment or by the precipitation of dissolved minerals from salt or fresh water
one of the major groups of rock that makes up the crust of the Earth; formed by the deposition of either the weathered remains of other rocks, the results of biological activity, or precipitation from solution
Different, but contemporaneous and juxtaposed, sedimentary rocks. Terrigenous facies are accumulations of particles eroded from older rocks and transported to the depositional site. Biogenic facies are accumulations of whole or fragmented shells and other hard parts of animals. Chemical facies result from precipitation of inorganic material from solution. The shapes and characteristics of facies may change as conditions change over time
rock formed of sediment, and specifically: (1) sandstone and shale, formed of fragments of other rock transported from their sources and deposited in water; and (2) rocks formed by or from secretions of organisms, such as most limestone Many sedimentary rocks show distinct layering, which is the result of different types of sediment being deposited in succession
Rock formed at or near the Earth's surface by the accumulation and lithification of fragments of preexisting rocks or by precipitation from solution at normal surface temperatures. Sedimentary rocks can be formed only where sediments are deposited long enough to become compacted and cemented into hard beds or strata. They are the most common rocks exposed on the Earth's surface but are only a minor constituent of the entire crust. Their defining characteristic is that they are formed in layers. Each layer has features that reflect the conditions during deposition, the nature of the source material (and, often, the organisms present), and the means of transport. See also sedimentary facies
Rocks in beds composed of particles of other rocks, organic matter, or materials deposited from solution in water Examples: limestone, sandstone, shale; most fossils are found in sedimentary rock
A rock resulting from the consolidation of loose sediment that has accumulated in layers Some forms of sedimentary rock are formed as chemical precipitates, such as salt and some forms of limestone
Sedimentary rock played a primary role in the formation of the Adirondacks, and is one of the three great rock classes that encompass all rocks Sedimentary rocks are formed at or near the earth's surface by the accumulation of particles in size varying from submicroscopic to boulder size Sediments accumulate, often to a thickness measured in miles The weight of the upper beds exerts enormous pressure on the lower beds causing heating, compaction, and cementing of the beds into rock layers Over time and in this manner, mud becomes mudstone and then shale, sand is consolidated into sandstone, etc Sedimentary rocks are easy to recognize due to their layered structure
Rock formed from the weathered products of preexisting rocks that have been transported by water, wind, or glaciers Sandstone is a type of sedimentary rock
A rock that formed from particles that were eroded from a previous rock, transported, deposited, and lithified Also includes rock that accumulated as chemical precipitates
rock formed from particles generally weathered and eroded from pre-existing rock material but also from the deposition of shells and other organic detritus (e g , carbonate rocks) or the precipitation of salts from solution
Rock made up of particles deposited from suspension in water The chief kinds of sedimentary rock are conglomerate, formed from gravel; sandstone, formed from sand; shale, formed from clay; and limestone, formed from soft masses of calcium carbonate There are many intermediate types Some wind-deposited sand is consolidated into sandstone
Rocks formed by the deposition, alteration and/or compression, and lithification of weathered rock debris, chemical precipitates, or organic sediments Also see clastic vs non-clastic sedimentary rocks
Rocks formed from material derived generally by erosion of other rocks and laid down by a chemical or mechanical process i e , limestone, shale and sandstone
Formed from the lithification (cementation) of sediment Sedimentary rocks may be composed of mineral or rock particles (clasts) to form sandstones, claystones or sediments of biological origin to form limestone and peat, or of chemical precipitation to form evaporites
a rock formed of fragments transported from their source, usually by water The sediments are usually laid down in layers Sandstone and limestone, the two major rocks found at Mammoth Cave, are both sedimentary
