MANY PEOPLE CONFUSE GEODES WITH NODULES. GEODES ARE CIRCULAR ROCKS THAT CONTAIN BEAUTIFUL CRYSTALS INSIDE. NODULES ARE ROCKS THAT ARE COMPLETELY FILLED WITH SMALL CRYSTALS SUCH AS JASPER AND RUBY. THE DIFFERENCE IS THAT A NODULE IS SOLID AND A GEODE CONTAINS ITS CRYSTALS IN A HOLLOW CAVITY. GEODES CAN CONTAIN MANY MINERALS, IN MANY DIFFERENT FORMS SUCH AS CALCITE, PYRITE, KAOLINITE, SPHALERITE, MILLERITE, BARITE, CELESTITE, DOLOMITE, LIMONITE, SMITHSONITE, OPAL, AND QUARTZ. GEODES ARE MOST COMMONLY FOUND IN BASALTIC LAVAS AND LIMESTONES. FOR MORE INFORMATION GO TO THE GEODE GALLERY.com. THIS IS MIA PALMER FROM DOOLEN MIDDLE SCHOOL FOR BEAR ESSENTIAL NEWS.
