The parent rock (protolith) is the rock type that existed before a rock is altered into metamorphic rock. For instance, shale (sedimentary rock) is the parent rock of slate (metamorphic rock).
These are rocks that are the source of, say, gravels or road metal.
Or they may be the source of or associated with the presence of, say, Kimberlite.
soil is in weathered parent rock
Limestone is the parent of rock of non foliated metamorphic. This is a very old type of rock.
It means the rock that a small piece broke off from. Outside our local library is a boulder quite different from our local sandstone. It is labelled as 'an erratic block of andesitic agglomerate' which broke off 'from the parent rock in Cumbria some millions of years ago'. It was carried about 120 miles by a glacier.
Parent rock. (apexvs)
the parent rock of obsidian is magma, because it is made from quickly-cooling magma after a volcanic eruption.
Nothing, Chert has a parent rock and is made of mostly fossils and silica. It is not a parent rock. It has a parent rock.
Limestone does not have a parent rock.
soil is in weathered parent rock
Phyllite is a foliated metamorphic rock whose parent rock is slate.
Limestone doesn't normally have a parent rock. One exception to this may be a detrital limestone, whose parent rock would however also be limestone!
Yes. Limestone is the parent rock, or protolith, of marble.
the parent rock helps protect soil
Soil comes from parent rock. Due to weathering the action of plant roots etc the parent rock is broken up and over many years gets incorporated into the soil. So the composition of the parent rock will affect the soil that develops over it. The soil could be lacking in certain minerals due to the parent rock. The soil could be acidic or basic due to the parent rock. But there is more to soil composition than just the parent rock.
Conglomerate Rock.
Marble!
rock called basalt
The reason why my parent rock in science because the teacher rock science before.
