Granite heated under pressure can form a type of metamorphic rock called gneiss. This process causes the minerals in the granite to recrystallize and align in distinct patterns, giving gneiss its characteristic banded appearance.
marble. Through the process of metamorphism, both granite and shale can be transformed into marble when subjected to heat and pressure. This process causes the minerals within the rock to recrystallize, giving marble its characteristic appearance and texture.
Granite is a widely occurring group of intrusive, igneous rocks that form at great depth and pressure under continents. The minerals in granite are primarily quartz, feldspar, and mica.
Sedimentary rocks such as sandstone and shale can form when materials are squeezed together due to pressure from overlying sediments and compaction. Igneous rocks can also form from intense pressure transforming existing rocks, such as with the formation of gneiss from granite under high pressure and temperature conditions.
Rocks such as gneiss and schist form under high temperature and pressure conditions found a few kilometers beneath the Earth's surface. These rocks are typically a result of metamorphic processes that alter existing rock types like granite or basalt.
Groundwater heated by magma can form geysers, where the pressure from steam and boiling water builds up underground until it forcefully ejects through the surface in a powerful spray. This process is what creates geothermal features like geysers and hot springs.
