Agates are commonly found as nodules formed within cavities of volcanic rocks. These cavities are formed by the gases trapped within the liquid volcanic material hardens. These cavities are then, over time, filled in with silica-rich fluids. Layers are deposited on the walls of the cavity slowly filling it in. Variations in the composition or in the conditions of the deposit result in variation in the successive layers as the cavity fills in. These layers result in bands of chalcedony, often alternating with layers of crystalline quartz forming the bands that are often associated with agates.
