Fluid inclusions in quartz of gold ore veins of deposit Sekuschiy (Chukotka)

Investigation of quartz fluid inclusions from gold occurrence Sekuscheye were studied. It was established that the homogenization temperature of most inclusions is about 340-350 °C. Carbon dioxide is the main component of the gas phase of inclusions; nitrogen and methane are present in smaller amounts. It is suggested that there are different types of fluid solutions that are involved in mineral formation.
