👉 Dynamogenous refers to a type of mineral that is found in the Earth's crust and can undergo significant changes during metamorphism or igneous activity. It occurs when magma, lava, or other fluids within the rock come into contact with the surrounding rocks, causing them to melt, cool, and solidify under the influence of heat and pressure. This process results in the formation of a new mineral, such as quartz, on top of the original rock.
