What Are Geodes?

Geodes are hollow, usually rounded cavities in a rock that are lined with crystals and other minerals. They are typically formed in igneous (volcanic) rock, though they can also be present in sedimentary rocks.

How Do Geodes Form?

Geodes typically start out as hollow gas bubbles in volcanic rock. Over time, hydrothermal fluids or groundwater deposit minerals within these gas bubbles, forming a crystal lining. Read more...

What Minerals/Crystals Are Found In Geodes?

By far the most abundant mineral found within geodes is macrocrystalline quartz (including amethyst), but calcite, pyrite, barite, celestite, & chalcedony (agate) are also frequently found. Geodes found at the same locality typically have similar minerals deposited inside.

What’S The Difference Between A Geode, Nodule & Vug?

Geodes are hollow cavities within the rock, while nodules are completely filled in with minerals. Vugs are irregularly shaped pockets typically along of vein or breccia while geodes are rounded or oblong in shape.

Where Are Geodes Found?

Geodes have been found in volcanic rock world wide, but some of the most prolific deposits include:

  • The Dugway geode beds in Western Utah.
  • The Warsaw Formation in the Keokuk region near the area where Missouri, Iowa, and Illinois.
  • The volcanic rock deposits in Southern Brazil and Uruguay which produce gorgeous and sometimes very large amethyst geodes.
  • The area near Chihuahua, Mexico produce abundant geodes called Coconut Geodes mined from about 100 feet below the surface.
  • What Is The Largest Geode Ever Found?

    Petrified Wood is a type of a fossil as it consists of fossil wood where all the organic materials have been replaced with minerals while retaining the original structure of the wood. These minerals are most often Silicates such as Quartz. Other minerals, Manganese, Iron and Copper, in the water or mud during the petrification process gives Petrified Wood a variety of color ranges: black - Carbon; green/blue - Copper; red/brown/yellow - Iron. Petrified Wood can preserve the original structure of the wood in all its detail all the way down to the microscopic level. Structures such as tree rings and the various tissues are often observed features. Although Petrified Wood can be found worldwide, it is rather rare in larger quantities and at times can be difficult to obtain by the average collector.

    Aragonite is a Carbonate mineral that can occur in conjunction with Calcium Carbonates. Aragonite differs from Calcite in the formation of the Crystal shapes which can be in lattice, crystal, columnar or fibrous in many different designs, shapes and sizes. Aragonite will form in mollusk shells, oceans and salt water caves as inorganic precipitates called marine cements and speleotherms. Ammolite is a form of Aragonite with impurities that make it iridescent and valuable as a gemstone.

    Geodes are geological rock formations which occur in sedimentary and certain volcanic rocks. They are essentially rock cavities or vugs with internal Crystal formations or concentric banding. The exterior is generally Limestone while the interior contains Quartz Crystals and/or Chalcedony deposits. If the Geode is completely filled with Crystal, being solid all the way through, it is then called a nodule.

    Quartz is the second most common mineral in the Earth's continental crust. It is mainly composed of Silica or Silica based minerals. Although Quartz is known by a variety of names, the most important distinction between types of Quartz is that of macro-crystalline, individual crystals visible to the unaided eye, and micro-crystalline, where aggregates of crystals are only visible under high magnification. There are many forms of Quartz including Chalcedony, Amethyst, Citrine, and Carnelian which are results of mineral impurities or heat treatments.
