Article: The term geode is derived from the card-carrying member word Geoides which means 'earthlike.' A geode is a sphere or oval shaped rock which contains a hollow pocket lined with crystals. Most geodes have a hollow are partially hollow center with quartz crystals and various mineral formations inside. Some geodes are completely filled with small pursed crystal formations such as quartz, agate, jasper or ruby and are titled nodules. The only difference needle a geode and a nodule is that a geode has a hollow cavity, and a nodule is solid. Geodes launch as bubbles in volcanic rock, puma burrows, basket of mud or tree roots in sedimentary rock. Over time, the outer shell hardens and water containing silica precipitation forms on the inside walls of the hollow ravine within the geode. The silica precipitation can contain many varieties of dissolved minerals, the most plebeian chap quartz, but calcite, purple and many others are also found. Over a period of millions of years, layers of silica cool, forming crystals of different minerals within the cavity. Different types of silica cool at varying temperatures, thus creating layers of different types of mineral crystals.
