Exposure on a cliff face would be caused by erosion, uplift, or faulting of the crust in an area that was at one time under water.
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.
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)
Limestone is primarily composed of the mineral calcite and may be very fine-grained, oolitic, or fossiliferous.
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.
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
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.
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.
They're made of limestone (chalk).
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.
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.
No, limestone made from precipitated calcite is not considered clastic. Clastic rocks are formed from fragments of pre-existing rocks, while limestone is formed through the accumulation of calcite deposits from the precipitation of calcium carbonate.
Limestones are sedimentary rocks made of skeletal remains. Limestones are recognizable because they react with Acid. Crystalline limestone are micro skeletons with large visible crystals. Micritic limestone is lithographic limestone and it is basically fine grained mud with micro-skeletons. Fossiliferous limestone is made with whole fossils in my experience mostly shells. Coquina is parts of skeletons pressed together. The difference between coquina and fossiliferous is that coquina doesn't have whole fossils. Lastly there is chalk. This is a lot of microorganisms remains pressed together.
