Geodes can form in any cavity, but the term is usually reserved for more or less rounded formations in igneous and sedimentary rocks. They can form in gas bubbles in igneous rocks, such as vesicles in basaltic lava; or, as in the American Midwest, in rounded cavities in sedimentary formations. After rock around the cavity hardens, dissolved silicates and/or carbonates are deposited on the inside surface. Over time, this slow feed of mineral constituents from grou… WebSedimentary rocks form on or near Earth’s surface. Eroded particles of rock are transported by wind, water, and ice and deposited on dry land, on the beds of rivers and lakes, or in the seas.
