Abstract
The gold-bearing Chaarat deposit is located in the Chatkal district of the Jalal-Abad region, Kyrgyz Republic. The Chaarat area is part of the folded area of the Middle Tien Shan and represents the central part of the Altaid Orogenic Collage. Fluid inclusion microthermometric analysis was performed for fluid inclusions in quartz in quartz vein from drill core at 80-250 m depth interval.Ten doubly polished sections samples approximately 200 μm thick, were prepared for this study. Samples were taken from from Adit , main vein from the contact zone and surface drill core. In terms of the number and the volumetric proportions of phases present in the fluid inclusions at room temperature, three major types of inclusions can be recognized at Chaarat Deposit. They are designated as vapor-rich (type I), liquid-vapor (type II) and aqueous liquid small shape (type III) inclusions. Fluid inclusion studies reveal homogenization temperatures of Th-350°C to 450° C, with mainly liquid and as much as 5% vapor. Two temperature peaks of Th-225°C to 320° C and 80° to 180° C occur in many samples.
