Metamorphic rocksare formed when existing rocks (igneous, sedimentary, or even older metamorphic rocks) are subjected to heat, pressure, and chemically active fluids, causing them to change (metamorphose) withou
Limestone, a sedimentary rock, will change into the metamorphic rock marble if the right conditions are met. What is the most common igneous rock? Granite: the most common igneous plutonic rock. Contains essential quartz, plagioclase and alkali feldspar, usually with hornblende and/or biotite and...
The protolith is subjected to heat and pressure causing profound physical and chemical change. The protolith may be sedimentary rock, igneous rock, or another (older) metamorphic rock. Metamorphic rock may be formed when magma is injected into the surrounding solid rock, as shown in Fig. 3.1b....

How does sedimentary rock change into igneous rock? Where do igneous rocks form? What are extrusive igneous rocks used for? How does sedimentary rock form into metamorphic rock? How are igneous rocks formed from a subduction zone? What general characteristics are used to identify igneous rocks?
The rocks are thus divided into three main groups: igneous, metamorphic, and sedimentary. Igneous rocks are formed from the solidification of molten material, metamorphic from a previously existing rock by some process of change such as temperature and pressure variations, and sedimentary from the ...
