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 type of rocks are an accumulation of particles (either clastic or chemical rocks)?
Sedimentary rocks are formed from the accumulation of particles, which can be either clastic or chemical in nature. Clastic sedimentary rocks are composed of fragments of other rocks and minerals, while chemical sedimentary rocks form from the precipitation of minerals from solution. Both types result from processes like erosion, deposition, and lithification. Examples include sandstone (clastic) and limestone (chemical).
What are three different origins for limestone?
Three different origins for limestone are Organic, Chemical and Bio-clastic Origins.
What is the most common non-clastic sedimentary rock?
The most common non-clastic sedimentary rock is limestone, which is primarily composed of calcium carbonate. It forms from the accumulation of organic remains such as shells and coral, or through chemical processes like precipitation from seawater. Limestone is widespread and found in many different environments around the world.
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, 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.

Is chalk clastic or non clastic?
Chalk is non-clastic, as it is primarily composed of the mineral calcite (calcium carbonate) formed from the remains of microscopic marine organisms such as plankton. These organisms contribute to the fine-grained texture of chalk through chemical precipitation rather than mechanical weathering or erosion.

Is limestone from shells chemical organic or clastic?
Limestone made from shells would be an organic sedimentary rock.
Is coal clastic or non-clastic?
Coal is considered a non-clastic sedimentary rock because it forms from the compressed remains of plant material rather than from the deposition of rock fragments or grains.
What is the most common non-clastic sedimentary rock?
The most common non-clastic sedimentary rock is limestone, which is primarily composed of calcium carbonate. It forms from the accumulation of organic remains such as shells and coral, or through chemical processes like precipitation from seawater. Limestone is widespread and found in many different environments around the world.
Is a loess a result of deposition or erosion?
Loess is a result of deposition. It is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust.
Is marble a clastic rock?
No, marble is not a clastic rock. It is a metamorphic rock that forms from the recrystallization of limestone. Clastic rocks are composed of fragments of pre-existing rocks or minerals that have been cemented together.
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.
How are non clastic rocks formed?
Non-clastic rocks are formed through chemical and organic processes. Chemical rocks like limestone are formed when minerals in water precipitate out and accumulate. Organic rocks like coal are formed from the remains of plants and animals that are buried and compacted over time. These processes occur without the transportation and deposition of sediments like in clastic rocks.
