👉 Rockelay is a type of rock in the geology of the Earth. It is composed primarily of silt and clay, which are also found on the surface of the Earth's crust. Rockelays are usually found near rivers or other bodies of water, where they can be disturbed by tectonic activity. They are typically found in areas with a high concentration of minerals like iron and nickel, as well as in regions where there is a large amount of sedimentary rock formation.
