| Almus agates which are forms of nodules like egg-shaped are located in the Eocene aged Almus volcanics in Tokat (Turkey). These nodules are surprise eggs in spherical or oval form ranging from a few cm to 25-30 cm. It is thought that the most effective reason for the formation of the magnificent texture and color combinations of the agates in the region is the iron element. In thin section studies, agate formations are composed of length-slow zebraic chalcedony and quart zine. In addition, curved fossil like structures composed of iron oxide minerals offer visual richness.The host rock in which the Almus agates are located is trachyte, which consists of sanidine, pla-gioclase microlites and small opaque minerals, in which microlithic porphyritic and flow (trachytic) texture are observed. As a result of the multipoint eds (field emission scanning electron microscope), it was determined that the quartz is composed of Si, O … |
