Dykes are geological formations characterized by vertical or near-vertical walls of rock that cut across existing strata. They are typically formed from molten magma that intrudes into cracks in the surrounding rock and solidifies. Dykes can vary in composition, size, and orientation, and they often exhibit features such as a fine-grained texture due to rapid cooling. Additionally, they can serve as indicators of tectonic activity and are commonly associated with volcanic regions.
