It is a sedimentary rock made almost entirely of bones and shells.
No.
Rock can be changed into metamorphic rock by heat and pressure.
the
Heat and pressure transform rock to metamorphic rock.
Any type of rock can become metamorphic.
No, coquina is not foliated. Coquina is a sedimentary rock composed of loosely cemented fragments of shells and coral. Foliation typically occurs in metamorphic rocks, where minerals are aligned in layers or bands.
where is coquina rock found
If a coquina rock is exposed to high temperatures and pressure, it would undergo a process called metamorphism. The minerals within the rock would recrystallize and reorganize, resulting in a new rock type known as a metamorphic rock. In the case of coquina, which is primarily composed of fragmented shell and coral pieces, these materials would likely recrystallize into new minerals such as calcite or dolomite. The original sedimentary structures of the coquina would be obliterated, and the rock would exhibit new textures and possibly foliation due to the pressure.
where is coquina rock found
Though coquina rock is relatively low density and soft, it does not float. Smaller pieces are often broken and washed around by waves.
A rock made entirely of seashell fragments is known as a coquina. Coquina rocks are formed from the accumulation and compression of broken seashells, creating a unique and porous sedimentary rock that is often found along coastal regions.
A metamorphic rock.
A sedimentary rock called coquina.
in a metamorphic rock you find rock.
No.
Chert is NOT a metamorphic rock.
Metamorphic rock displaying banding is referred to as foliated metamorphic rock.
