Metamorphic processes, involving the transformation of existing rocks under high temperature and pressure, are the primary mechanism for mineral formation.

Limestone is a sedimentary rock, not a magmatic rock.

Crystallization is the process by which minerals form from a magma as it cools and solidifies.

Gold is a common mineral formed through hydrothermal processes, where hot water solutions deposit minerals in fractures and veins.

Sedimentary rocks are formed through the accumulation and compaction of sediments, which are derived from the weathering and erosion of existing rocks.

Limestone is a sedimentary rock formed through the chemical precipitation of calcium carbonate from seawater or groundwater.

Metamorphism is the process by which existing rocks are transformed into new rocks under the influence of high temperature and pressure.

Garnet is a common mineral formed through metamorphic processes, where high temperature and pressure cause the recrystallization of existing minerals.

Crystallization is the process by which minerals form from a magma as it cools and solidifies.

All of the above factors can influence the formation of minerals.

Evaporation is the process by which minerals form from the evaporation of water from a solution.

Sulfur is a mineral that can form through sublimation, where it crystallizes from a gas directly into a solid.

Crystallization is the process by which minerals form from a lava as it cools and solidifies.

Calcite is a common mineral formed through sedimentary processes, where it precipitates from seawater or groundwater.

Hydrothermal alteration is the process by which existing minerals are altered by hot water solutions, often resulting in the formation of new minerals.
