because they are mostly made up of the miilion years
The cementing material could be calcite, clay minerals, iron minerals, or quartz in a clastic sedimentary rock.
Sedimentary rock
sedimentary rock
Sedimentary rock is a type or classification of rock so designated by its method of formation. Minerals are inorganic naturally occurring solids, with a definite chemical composition and a crystalline structure.
Sandstone is a sedimentary rock.
Sandstone is the sedimentary rock formed from weathered rock.
The rock described would be a clastic sedimentary rock.
No it is not. Sedimentary rocks are made of minerals.
These minerals are called evaporites.
The color of sedimentary rock changes during metamorphism due to minerals. New minerals introduced can change the color of the rock.
When sedimentary rock is buried, it is subjected to increased pressure and temperature. This leads to compaction, where the rock grains are tightly packed together, and often leads to the recrystallization of minerals. Over time, these changes can transform the sedimentary rock into metamorphic rock.
The cementing material could be calcite, clay minerals, iron minerals, or quartz in a clastic sedimentary rock.
It is said to be a clastic sedimentary rock.

They all contain minerals.
The sedimentary rock formed from minerals precipitating from a solution is called chemical sedimentary rock. It is formed through processes such as evaporation or chemical reactions, without the involvement of organic material or clastic particles.
