How to Hunt for Geodes Geodes are typically agates. Agates are very common stones, and usually do not fetch a high price, but they are gorgeous to look at. Geodes in particular can be quite incredible, because they are like little miniature caves. On the outside, they look like plain, rough stones.

What in the World is a Geode? A geode is a type of rock formation that occurs when a pocket of air or gas is trapped and forms a cavity in sedimentary or igneous rock. A hard crust forms around the outside of the cavity.Groundwater, which often carries dissolved minerals in solution, seeps through the rock over a long period of time.lear quartz, smoky quartz, amethyst, calcite, celestite, and chalcedony are examples of some minerals you may find inside a geode. Geodes from the same location often have the same type of mineral crystals. Some geodes are filled in with beautiful layers of mineral crystals.

Geode State Park, IA Geode State Park has been a traditional favorite for locals as well as out-of-state visitors. The park is named after the state rock which is frequently found in the area. Geodes bring rock hounds to the local area in search of this elusive prize. A display of geodes, with mysterious crystal formations in their hollow cavities, can be seen at the park office.

Geodes The term geode is derived from the Greek word Geoides which means earthlike.. A geode is a round rock which contains a hollow cavity lined with crystals. Rocks which are completely filled with small compact crystal formations such as agate, jasper or chalcedony are called nodules. The only difference between a geode and a nodule is that a geode has a hollow cavity, and a nodule is solid.

Where do geodes come from? But where do geodes actually come from? It turns out that what looks like a solid entity on the outside begins with an absence of material. A geode typically begins when a cavity forms in a rock, which can happen several ways. Cavities are most common in igneous rock created by cooling lava or magma.

Geodes Volcanic ash beds, or regions containing limestone, are common geode locations. There are many easily accessible geode collecting sites in the western United States, including in California, Arizona, Utah and Nevada. The state of Iowa also has geodes, in fact, the geode is their state rock.Hauser Geode Beds.he most famous of these sites is called the Hauser Geode Beds, which are located at Wiley Well in the northern region of Imperial Valley, CA. In the same area there are also the North Black Hills Geode Beds and the Cinnamon Geode Beds.

Where do geodes come from? Which minerals end up as crystals in a geode varies by location and conditions such as temperature, acidity, and the type of rock the geode forms from. For instance, quartz crystals are most common in igneous geodes.eodes can also form in sedimentary rocks such as limestone or sandstone. The cavity in these rocks is usually formed from a solid core. A mass of minerals, or nodule, in the sediment may begin to dissolve and leave space behind.

- Geodes (Greek γεώδης - ge-ōdēs, earthlike) are commonly independent spherical masses of resistant mineral matter that are usually hollow. The extreme filling of a geode so that it is solid is also common.Some people refer to completely in-filled geodes as nodules, but the two names are not always consistently used.eodes (Greek γεώδης - ge-ōdēs, earthlike) are commonly independent spherical masses of resistant mineral matter that are usually hollow.

What Is a Geode? The only way to discover the beauty inside of a geode is to crack it open with a rock hammer or cut it open with a rock saw. Geodes will vary widely in terms of their size, crystal formation, and colors. Some of the most prized geodes are those that feature rare black calcite or amethyst crystals.

Where do geodes come from? Geodes can also form in sedimentary rocks such as limestone or sandstone. The cavity in these rocks is usually formed from a solid core. A mass of minerals, or nodule, in the sediment may begin to dissolve and leave space behind.In other cases, organic matter such as coral, a fossil, or a piece of wood buried in the sediment weathers out over time.avities are most common in igneous rock created by cooling lava or magma. Usually this happens when a bubble of carbon dioxide and water vapor forms in flows of lava, “much like bubbles in carbonated beverages,” says George Harlow, an expert in minerals and crystals at the American Museum of Natural History.

What is a geode? What minerals are rare? Large geodes for sedimentary geodes would be any geode over the size of 6 to 8 inches. Volcanic geodes are considered large after 4 to 5 inches. The hollowness of a geode also contributes to the value. The more hollow the geode the bigger the crystals and more minerals that can be found inside.arge geodes for sedimentary geodes would be any geode over the size of 6 to 8 inches.
