Geode Rocks With Crystals Inside

The geode at the left and the one at the top of the page are both dugways from utah.

Geode rocks with crystals inside. Over time as mineral rich water seeps into the rock it beings to deposit tiny crystals on the sides the hollow cavity. These dugway geodes have bands of blue and pink. And depending on the minerals that make up the geode different geodes will contain different kinds of crystals such as amethyst agate and quartz. Simply speaking geodes are hollow rocks that contain an insanely beautiful array of crystal formations inside.

Geodes in sedimentary rocks are usually found in limestones dolomites and calcareous shale in these deposits a gas filled void can serve as the opening for geode formation. Geodes are rounded hollow voids in rocks filled with crystals and other minerals. They are typically formed when air bubbles inside of volcanic rock form hollow cavities. Shells tree branches roots and other organic materials often decay away to leave a void for the formation of mineral materials.

The crystals are formed by the filling of vesicles in volcanic and sub volcanic rocks by minerals deposited from hydrothermal. All geodes are not created equal the first one is quite hollow but for a nice layer of medium sized blue crystals. Geodes derived from the greek word γεώδης meaning earth like are geological secondary formations within sedimentary and volcanic rocks geodes are hollow vaguely spherical rocks in which masses of mineral matter which may include crystals are secluded.
