Topic 1: Mechanism of Vertical Element Migration and Establishment of a Geochemical Block Three-Dimensional Model

Research Objective: Through migration experiments, in-situ observations of migration processes, and quantitative simulations, combined with research findings from various mining areas, establish three-dimensional geochemical block models for gold, copper, and uranium deposits. This will provide theoretical support for the study of deep penetrative geochemical technologies.

Assessment Indicators and Evaluation Methods:

Establish three geochemical block three-dimensional models for gold, copper, and uranium deposits.  Publish 8 papers, with no fewer than 3 SCI papers.  Apply for 4 patents.  Train 5 graduate students.
