How are clastic limestone and fossiliferous limestone deposition different?
Clastic limestone is made up of fragments of pre-existing limestone, while fossiliferous limestone contains fossil remains. Clastic limestone forms through mechanical processes like erosion and sedimentation, while fossiliferous limestone results from the accumulation of marine organisms' shells and skeletons.
What is the difference between fossiliferous limestone and oolitic limestone?
Fossiliferous limestone has larger fossils in the rock and is of biochemical composition where as the oolitic limestone doesn't have any fossils and has a chemical composition. The Oolitic limestone has spherical grains that resemble miniature pearls (they are called ooliths or ooids). Both do effervesce in diluted HCL(acid)
What kind of grains does limestone have in it?
Limestone is primarily composed of the mineral calcite and may be very fine-grained, oolitic, or fossiliferous.
How does fossiliferous limestone form?
Fossiliferous limestone forms when the remains of marine organisms, such as shells, corals, and algae, accumulate on the ocean floor. Over time, these remains become compressed and cemented together to form a solid rock known as fossiliferous limestone. This process typically occurs in shallow, warm marine environments.
What Organic sedimentary rock is formed from layers of bones and shells?
The organic sedimentary rock formed from layers of bones and shells is called limestone, specifically fossiliferous limestone. This type of limestone is composed mainly of calcite, which is derived from the calcium carbonate found in the shells and skeletons of marine organisms. Over time, the accumulation and compaction of these biological materials create the rock. Fossiliferous limestone often contains visible fossils, providing insights into past marine environments.
What is fossil rich limestone?
Fossil rich limestone is limestone with various sea creature fossils in it such as shells. It is organic and fine grained. It is sedimentary... Yea that's it :P
Where are Fossiliferous grosopod found?
Fossiliferous gastropods are found in a variety of locations around the world, including sedimentary rocks, marine deposits, and fossil beds. Some common sites where fossiliferous gastropods are found include limestone formations, shale layers, and ancient sea floors. These fossils offer valuable insights into the evolution and diversity of gastropods over millions of years.
What is a organic sedimentary rock formed form layers of bones and shells?
An organic sedimentary rock formed from layers of bones and shells is called limestone, specifically fossiliferous limestone. This type of rock is composed mainly of calcium carbonate derived from the accumulated remains of marine organisms, such as corals and mollusks. Over time, the accumulation of these biological materials, along with sediment, undergoes lithification, resulting in the formation of limestone. Fossiliferous limestone often contains visible fossils, providing insights into the ancient environments in which it formed.
Is a petoskey stone clastic?
A "petoskey" stone was originally an fossiliferous (with a coral fossil), organic (sedimentary) limestone. The original limestone has been glaciated and pieces of the fossiliferous limestone containing the corals have been plucked form their bedrock matrix and rounded into pebbles as they have been carried along by ice. When the ice melted these pebbles have been dropped into whatever was below them. This means a petroskey stone is a clast in a "new", modern clastic rock. However the stones themselves are not originally from a clastic rock, they are sedimentary in origin.
What rock is the white cliff of Dover made out of?
They're made of limestone (chalk).
What is a limestone scar?
A limestone scar is a natural geological feature formed by the erosion of limestone rock, typically in upland areas. It often results in a steep cliff or slope that is characterized by rocky outcrops and ledges. Limestone scars form over long periods of time due to the dissolution of the rock by chemical weathering processes.
What kind of limestone might be deposited in Mammouth Caves?
Mammoth Cave is typically associated with the Happy Hollow Member of the Girkin Limestone, which is a fossiliferous, marine limestone deposited in a shallow, tropical sea during the Mississippian Period. This limestone contains abundant fossilized shell fragments and marine organisms, reflecting the environment in which it was formed.
