Sedimentary Rock

Dolomite is a carbonate mineral, and is generally used for a variety of purposes. This includes its use in the production of magnesium, as a concrete aggregate, and for ornamental purposes too.

Coquina shells are not living creatures and do not dig. They are made up of fragments of shells and coral that are cemented together to form a sedimentary rock. They are typically found near shorelines and can be buried at varying depths depending on local sedimentation processes.

• Limestone has greater strength and better bonding capacity.
• Limestome is crushed in to fine particles in the preparation of cement
• Limestone is the major constituent in cement of about 60-67%.
  

No, sedimentary rocks are classified based on their grain size, composition, and texture, not by whether they are foliated or nonfoliated. Foliation is a feature typically found in metamorphic rocks, not sedimentary rocks.

Erosion, transportation of the eroded material, deposition of this material then lithification.

The Old Man of Hoy, (formed of Old Red Sandstone) is a 449-foot sea stack on the island of Hoy. The island of Hoy is part of the Orkney archipelago and is off the north coast of Scotland.

By the same process used to make any other sedimentary rock. The original rock will break down through weathering into small particles, erode to a place of deposition, undergo compaction and cementation, creating a new sedimentary rock.

Limestone is made out of Calcium Carbonate CaCO3 .

Calcium carbonate is the active ingredient in agricultural lime and it is from this that the rock it was mine from gets its name.

A laccolith is an igneous formation between two sedimentary layers

Delicate Arch, at Arches National Park in Utah, is composed of sandstone.

The two major processes involved in the formation of sedimentary rock include deposition (in which sedimentary material is deposited in an area) and cementation (in which that material becomes glued together overtime).

Bedding planes in sedimentary rocks indicate the separate layers or strata in which the sediment has been deposited over time. These planes can provide important information about the environment in which the rock was formed, including factors like sedimentation rate, depositional environment, and past geological events.

the most common minerals in clastic sedimentary rocks are likely

Yes as petroleum id derived from oil and oil only forms in very specific geological requirements. E.g. the length of the carbon chains in the petroleum depends on what carbons and other compounds formed the oil.

what is the texture of all inorganic land derived sedimentary rocks

Usually not, but it depends on the types of materials in it (if they are magnetic then it will be).

No. Limestone and shale are sedimentary rocks the form by different processes. Limestone is a biological sedimentary rock that forms from the carbonate shells of organisms. Shale is a clastic sedimentary rock the forms from the settling of fine-grained particles of mostly silicate minerals.

Normally, sedimentary chalk and limestone would be white (or whitish or greyish). The colour of slate can range widely, even creating green, or blue slate. Conglomerate is often coloured by the clay that surrounds the stones embedded in the clay. Even white chalk could appear reddish if contaminated enough by iron sulphates, etc.

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.

The pressure is from the weight of rock and sediment layered on top of the rock in question.

The elastic modulus of shale is between 1-70 GPa

Yes, mostly gravel from a landslide, and organic rocks

No. It is an igneous rock, meaning it cooled from molten rock. Specifically, obsidian is volcanic.
