| Abstract: | This paper briefly introduces the theoretical basis and obtained representative results inthis study field, and the application of Sr-Nd isotope evolution tracing techniques in investigating the metallogenic capability of regional basement and ore-bearing formations, as wellas the nature of water-rock exchange and depositional environment, in expounding the degree of water intervention and bedrock participation, characteristics of water and rock soucesand balance condition of isotope exchange. It provides evidence for the study on metallogenicenvironment and leaching condition of ore deposit. |
