Abstract: Adopting network, database and VR technologies, this research develops a comprehensive database of typical deposits and three-dimensional dynamic simulation modules of typical deposits, which move typical geological model to network. The research, relying on the virtual simulation project of Jilin University, designs and develops a Web-based simulation system for virtual deposits. The main function of the simulation demonstration is to realize the dynamic show of the ideal metallogenic mode process, providing people more direct understanding of the geological meaning. Users can study the huge amount of data of typical deposits from the network. The system has changed the traditional way of information visibility and geological information management of ore deposits.
