All clastic rocks are made up by rock fragments of different size. Siliciclastic rocks (rocks composed chiefly of broken up silicate material) are classified depending on what the predominant grain size is, how wide the spread in grain size is, what the form of the grains are and what the contributing minerals are.
Very badly sorted clastic rocks with rounded fragments chiefly of gravel size is called conglomerate.
Well sorted silicate material, mainly of sizes between 0.1 to 0.2 mm diameter, is called sandstone (made up of fine sand).

What type of rock is clastic and non-clastic?
Clastic rocks are made up of broken fragments of pre-existing rocks, while non-clastic rocks are formed from chemical processes or organic matter. Sandstone is an example of a clastic rock, formed from the accumulation of sand grains, while limestone is a non-clastic rock formed from the accumulation of organic material or through chemical precipitation.
What clastic sedimentary rock is made from finest sediment?
Metamorphic rock
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 are Rocks made from fragments of minerals or other rocks called?
Clastic sedimentary rock.
Is quartz clastic?
No, quartz is not clastic. Clastic refers to sedimentary rocks made up of broken fragments of minerals and rock material. Quartz is a mineral composed of silicon and oxygen, and it can be found in various types of rocks, including igneous, metamorphic, and some sedimentary rocks.
