摘要
Carbon and oxygen isotopic values provide criteria for the evaluation of depositional environment. Sixteen siderite samples from the Dajing ore deposit, Inner Mongolia, China, were analyzed in order to determine depositional environments. Together with tectonic setting, deposit geology, and rare-earth element composition, the hydrothermal systems are recognized in a lacustrine setting in the early mineralization, which is important not only for a better understanding and interpretation of the genesis of the Dajing deposit but also for exploration of hydrothermal events in the lacustrine environment.
