Chubuk Thundereggs
from few agate sites around Chubuk (north of Ankara), Turkey
 .
    Turkey is getting to be renowned for having one of few sites around the world where high percentage of agate have been found with pseudomorphs after aragonite/calcite and sagenite inclusions.  The agates are actually the forms of thunderegg cores which the shells have mostly been eroded away as a result of exposure to weathering for millennia and it is rare to find any agate cores with thunderegg shells still attached to them.. The cores were dug from the several meters of clay layers that has been decomposed from the pertile(rhyolitic) lava beds.
     The zeolites possibly laumonite sometimes encrusted with calcite have grown in the thunderegg cavities before being replaced and preserved by the gentle growth of agate and the colors tend to come in a range from white to to brown, sometimes black. Occasionally, the agates with reddish to yellowish colors have been found.  Some thundereggs contain highly contrasting white and black "waterline" layers.
