Clastic rocks are sedimentary rocks formed from pre-existing fragments of minerals. Fossiliferous rocks are formed in the same way, except that they contain fossils.

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 are three different origins for limestone?
Three different origins for limestone are Organic, Chemical and Bio-clastic Origins.
What is sedimentary rock formed by shells?
Limestone can be formed partly or mostly by visible shell fragments. .
What is the most common non-clastic sedimentary rock?
Type your answer here... Limestone
Did shale come from limestone?
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.
Is a limestone made from precipitated calcite clastic?
No. Granite is igneous, formed from slow-cooling felsic magma.
Is chalk clastic or non clastic?
Limestone is chemical; though in certain cases, limestone may be organic, when it is composed of the dead remains of organisms (fossils). That's called fossiliferous limestone, or fossil-rich limestone, but regular limestone is just chemical.

Is limestone from shells chemical organic or clastic?
Limestone made from shells would be an organic sedimentary rock.

Limestone can be formed partly or mostly by visible shell fragments. .
What three steps are involved in clastic rock formation?
Deposition, compaction, and cementation are the three steps needed to create a clastic rock formation. Clastic rock is made out fragments of other rocks.
Is limestone metamorphic?
No limestone is sedimentary. It can be either an organic sedimentary rock, or a clastic sedimentary rock.
A limestone that contains fossils would be classified as what type of sedimentary rock?
clastic

What is the sequence of the lithification of a clastic rock?
Weathering and erosion from an existing rock, transportation and deposition, compaction and cementation.
