What are organic sedimentary rocks?
Organic sedimentary rocks like coal and some limestones, are composed of particles created by life processes. In the case of coal it is plant remains. With limestones, it is the shells and secretions of small marine organisms.
What materials are found in sedimentary rock?
Oil and gas were formed after layers of organic matter were covered by sedimentary deposits, so are found in or below sedimentary rocks today
What sedimentary rocks have plant fossils?
Although any sedimentary rock can contain plant fossils, the fossils themselves are likely to be coal. Coal itself is a sedimentary rock, and this is entirely composed of plant fossil, but for the physical evidence of the existence of a plant, you would be lucky to find an intact sample, as after the death of the plant it crumples and wilts, and then sedimentary processes crush it. It is estimated that for every metre of coal measure, there was 20 metres of plant material. Any rock can contain a plant fossil, but it is rare to find a plant fossil outside of a coal measure. An example of a plant fossil outside of a coal measure would be a bed of shale with a root-like structure in it. This could be in-filled with any soluble mineral. The history would be that the shale was uncovered by natural processes, it had a crack in it, a seed fell into the crack and the tree grew inside the crack, spreading its roots. Later, after the tree died and rotted away, the impression was in-filled and thus preserved.
Do people have animal cells or plant cells?
Humans are composed of animal cells. Plants are composed of plant cells
Is Kaibab an organic sedimentary rock?
Kaibab Limestone is not an organic sedimentary rock, but classified only as a sedimentary rock. Organic sedimentary rocks form from the remains of carbon rich plant life normally.
What is the class that includes sedimentary rocks which are deposited from a solution made by organic processes?
Sedimentary rocks are broken into two classes: clasticand chemical. Clastic sedimentary rocks are composed of rock particles, and chemical sedimentary rocks are composed of precipitation of minerals in solution.
A sedimentary rock composed of combustible matter derived from the partial decompostion of plant material?
apatite
Are conglomerates chemical or organic?
organic sedimentary rocks such as coal and some limestones which form from the accumulation of plant or animal debris.

What Can be found in sedimentary?
Fossils, sand grains, rocks, pebbles, boulders, clay particles, calcite, ancient plant debris--all depending on the rock's formation.
First step of coal formation is what?
The first stage in coal formation is the deposition of material composed of twigs, leaves, branches, and other plant debris..
What are sedimentary rocks made of?
Sedimentary rocks can be made from any kind of material, from other rocks to shells to plant material. Basically, any rock, from metamorphic to igneous and even to sedimentary, can be weathered and eroded. These particles and grains can be carried great distances by wind, water, ice, etc. before they are deposited and lithified (cemented) back together to form sedimentary rocks.

What is the first stage of coal formation?
The first stage in coal formation is the deposition of material composed of twigs, leaves, branches, and other plant debris, containing about 75% to 90% water.
What materials are found in sedimentary rock?
Oil and gas were formed after layers of organic matter were covered by sedimentary deposits, so are found in or below sedimentary rocks today
Why is coal a sedimentary rock?
Coal is a sedimentary rock because it is formed from plant debri or the remains
Oil and coal are?
Oil is a concentrated by-product from the decay of ancient plant and animal remains on the ocean floor and is considered a natural resource but not a mineral. Coal deposits are composed of the remains of mostly plant life that has undergone sedimentation and lithification. It is not considered a mineral, but a sedimentary rock.
