| Yamadağ Volcanics which is one of the examples of the Late Miocene volcanism in Eastern Anatolia covers large areas within the boundaries of Arguvan county of Malatya. The gemstones, subject of this research range from a few centimeters to about 30-40 cm in size and are formed in the cavities of the basalts beonging to Yamadağ volcanics. These gemstones seem to have formed as veins extending in east-west direction and consist of opal (opal-CT) and chrysocolla. Opal formations have various colours such as white, brown, yellow and greenish, while chrysocolla formations are bluish-greenish in color. both opal and chrysocolla are of massive type and their fresh surfaces display waxy luster. Mineral paragenesis and formation conditions of gemstones and are determined by applying XRD, SEM, FT-IR techniques. ICP-MS technique is used for the determination of the geochemical compositions.
