BAKER RANCH THUNDEREGGS FOR SALE

Baker Egg agate (also known as Baker Ranch agate) is a type of agate that formed as thundereggs (Lithophysae) from a primarily rhyolite-perlite host rock. They are collected from an area southwest of Deming, New Mexico that was formerly known as Baker Ranch. These thundereggs are unique in that they exhibit vibrant coloration that is typically only found in agate nodules (amygdaloids). Thundereggs are rarely found in any other color than white, blue or grey-blue, yet Baker Egg Mine produces mixtures of red, yellow, black, white and in rare cases, green agate. This is due to the unique geologic history of the area where rhyolitic lava deposits (thunderegg producing) over millions of years, were disrupted by a mixture of geologic forces and the introduction of basaltic and andesitic lava flows. These additional lava flows are believed to have provided the minerals necessary for the variety of coloration found in Baker Egg agates (thundereggs).
