The agates from Cubuk (region North Ankara) are usually found in the rhyolites lava beds and andesite and are coming from the volcanic Miocene age of about 16 – 18 million years ago. The agates in rhyolite were deposited as open space fillings, in crevice- and fissure-vein cavities. These agates included high concentric sagenitic banded and have bright colours. These agates are most of the time irregular. You can find some regular like thundereggs. The agates are often pseudomorph crystal (group of zeolotic, mostly laumontite, perlialite, natrolite) included with sagenite. These agates contains the following minerals: Al, Cu, Fe, K, Mn, Na, sb, Zn, Zr,. Some agate are encrusted with calcite rhombohedral, aragonite, common opal, cinnibar. Some unknown minerals have grown in the agate cavities before being replaced and preserved by the gentle growth of agate. The colours tend to come in a range from white to brown, black, blue, red, yellow, green, grey, white and lavender. Until now it is unknown how sagenite banded came in the Cubuk agates. My theory is that Cubuk agates contains often organic oil. Because of the chemical process (+/- 200 °C ) the sagenite banded developed.
Actually you can find agates everywhere within Turkey, but the most beautiful agates come from North of Ankara, Cubuk. Within an area of 30 kilometers of Cubuk you can find agates. It is a volcanic place at 2000 meter high. In Turkey you can also find agates in Yozgat, Tokat, Amasya, Sinop, Kastamonu, Eskisehir, Izmir, Canakkale, Kütahya, Denizli, Mugla, Van, Agri, Ararat, Erzincan, Hatay, Kars, Sivas and Hakkari. In Kizilcihamam Camlidere (also in North Ankara) also very nice agates are found, but the Turkish Government made a geologic park, which is not public anymore. Also a 10 kilometers area in Cubuk, Ankara is forbidden for people/companies to dig agates because there are also perlite mines (MTA Turkish Government) in this area. Also there is a gold mine but this one is already closed.
