MetamorphismThe process where rocks are transformed into new types of rocks due to changes in temperature, pressure, or chemical environment. This transformation occurs while the rock remains mostly solid (not melting).Agents of Metamorphism:Temperature:Elevated temperatures, typically above 150°C, are a primary driver for metamorphic reactions, causing minerals to recrystallize or new minerals to form. Pressure:Pressure can be either confining (equal in all directions) or directed (differential stress), which can cause the alignment of minerals or the development of foliation (layered structure). Fluids:Fluids, often hot water with dissolved ions, can facilitate chemical reactions and mineral transformations. Physical Changes in Rocks•Recrystallization: Formation of new mineral grains.•Foliation: Layered or banded appearance due to pressure.•Increased density: Rocks become more compact.•Deformation: Bending or folding of minerals.Chemical Changes in Rocks•New minerals form (e.g., clay minerals turning into mica).•Elements may migrate due to fluids.•Original minerals become unstable and transform.Example: Shale → Slate → Schist → Gneiss (progressive mineral change)translate to Tagalog
