Abstract: | Based on the results of previous studies and under the direction of the theory of “ore deposit genesis”, the authors made
use of high temperature and high pressure experimental facilities and conditions at the Tectono-geochemistry Research Room
under the State Key Laboratory of Ore Deposit Geochemistry, Institute of Geochemistry, Chinese Academy of Sciences, and put
the focus on the multi-source of tectonically controlling ore-forming materials, the characteristics of multi-stage and multi-episode
hydrothermal activities and mineralization and the characteristics of multi-genesis and multi-ore deposition so as to shed
light on the metallogenic mechanisms of super-large Cu and Au deposits. In addition simulating experiments were made on multi-stage
and multi-episode tectonic activities and rock and ore deformation, multi-stage and multi-episode tectonic activities and
mobilization and migration of ore-forming materials, and multi-stage and multi-episode tectonic activities and superimposition
and enrichment of ore-forming materials. The experimental results showed that under the action of multi-stage and multi-episode
tectonic stress the deformation and fragmentation of not only rocks and ores have been intensified, and but also the ore-forming
materials originally disbursed in the rocks and ores have been mobilized and migrated and superimposed and enriched. The experimental
results also provided the scientific experimental data and grounds for deep-going research on the rules of metallogenesis
and geneses of super-large ore deposits in the Dexing region, Jiangxi Province. |
