The rock was initially melted, which suggests an igneous origin. However, after it erupted, it would have cooled and solidified at the surface, making it an extrusive igneous rock. As it undergoes erosion, it would have broken down into sediment and eventually deposited, becoming a sedimentary rock. Finally, lithification would transform the sedimentary rock into a new sedimentary rock. Therefore, the entire sequence involves both igneous and sedimentary rocks.
