All rock types can be formed from any other rock type.
Conglomerates form from clastic sediments which are products of weathering, so, conglomeratic materials could be formed from any other rock type. Conglomerate itself is an Example of Mechanically formed Sedimentary Rock.
A metamorphic rock.
Sedimentary rocks are formed when other rocks (igneous, metamorphic, or sedimentary) are weathered and eroded and their sediments are compacted and cemented together. Metamorphic rocks can be formed when heat and pressure is applied to any type of existing rock. Igneous rocks are formed when magma cools. The magma can be made up of melted rocks of any kind (sedimentary, igneous, or metamorphic). The cycle repeats itself all the time and all of the rocks can come from any other kind of rock.
A metamorphic rock.
rock is melted to form molten rock, then as the lava hardens, it forms any type of igneous rock
The lava can cool in to any type of rock it depends on how it cools. And the type is igneous rock.
Soil can be formed from the erosion and deposition of any kind of rock: igneous, sedimentary, or metamorphic.
Siltstone can be formed from the eroded and transported particles of any rock type.
technically, quartz is not a rock. it is a mineral. quartz can be found in any type of rock
It could be any type of rock (sedimentary, igneous, or metamorphic).
Any rock can become a metamorphic rock. To become a metamorphic rock the rock must undergo heat and/or pressure, but not so much that the rock melts. Should the rock melt it would become an igneous rock.
No. Tuff is a type of rock formed from volcanic ash. It does not have any gemlike qualities.
