Volcanic rocks are igneous rocks that form from the solidification of molten magma erupted from volcanoes. These rocks are typically formed at high temperatures and pressures, either at the Earth's surface in the form of lava flows or as pyroclastic material during explosive volcanic eruptions. Volcanic rocks are characterized by their fine-grained texture and often contain minerals such as quartz, feldspar, and mica. Studying volcanic rocks can provide valuable insights into the Earth's geological history, as well as help us understand processes such as plate tectonics, volcanic eruptions, and the formation of mineral deposits. Researchers often analyze the composition, texture, and age of volcanic rocks to better understand the dynamics of volcanic systems and the evolution of volcanic provinces.
