Igneous rocks-after having the chance to cool down after a melt
(metamorphic rocks need pressure as well)
If the rock becomes hot enough to melt then this is an igneous rock. If however the rock does not melt, but the temperatures cause the rock to change then it is a metamorphic rock.
a metamorphic?
By the metamorphosis of limestone, marble is formed. By the thermal decomposition of limestone, quicklime is formed. Which process depends on the temperature and pressure.
gneiss
Quartzite, granite, and sandstone are all types of sedimentary or metamorphic rocks. They are related in the sense that they are formed from different processes involving the compression and transformation of sediments. Quartzite is derived from sandstone through intense heat and pressure, while granite is an igneous rock that forms from the cooling and solidification of molten magma. Sandstone, on the other hand, is formed from sand particles that are compacted and cemented together over time.
Sedimentary rocks
metamorphic rocks
As sandstone is a sedimentary rock formed from grains of sand over millions of years), applying heat and pressure is likely to pulverise the sandstone.
Sandstone can be metamorphosed into quartzite. Heat and pressure bake the sandstone and it becomes extremely hard.

Heat and Pressure
Sandstone that has experienced heat and high pressure can form a metamorphic rock called quartzite.

Both sandstone and siltstone are clastic sedimentary rocks formed by broken fragments of rock being deposited and then turned into solid rock by heat and pressure. The main difference is in grain size. Sandstone has larger grains than siltstone.
