| Transition of Tectonic and Dynamic Regime and Mineralization |
| In the process of mineralization, transition of tectonic and dynamic regime may play a fundamental role, controlling the critical transition and forms of mineralization parameters. Taking gold deposits in Jiaodong as an example, combined with related problems both in China and abroad,this paper illustrates multi-dimension transition of tectonic and dynamic regime and its induced accidental geological process and associated mineralization, describes in detail the critical transition phenomena in the shear-belt structure, and points emphatically out that the local transition under the overall structural setting (e.g. local extension under the overall compressional setting and local trap under the full-apart basin) is a common ore source-transportation-concentration structure. Driven by transition of tectonic and dynamic regime, the induced transition of multi-parameters serves as one of the mechanisms for forming large-size deposits. |
