Towards a Geological Digital Twin: Integrating Multi-Dimensional Geological Models for Comprehensive Earth System Representation
Year: 2025
Type: article
Abstract: . Understanding and managing Earth's complex geological systems are crucial for sustainable development and disaster mitigation. This paper details the National Geological Data Center's (NGDC) foundational efforts in China towards a comprehensive Geological Digital Twin. Guided by principles of integrated planning, standardization, and technology-driven services, NGDC has built a robust data infrastructure and developed extensive multi-dimensional geological models. We highlight innovative practices in establishing a standardized "receive, manage, utilize" data management system, integrating vast multi-source, multi-scale geological data into cohesive database clusters, and deploying open service platforms, including an internationally recognized geological data publishing system. Key achievements include the construction of China's most extensive 1:50,000 regional geological map database, covering half of the landmass, a comprehensive mineral deposit database, and a widely utilized online geological map service. These integrated multi-dimensional models serve as a digital replica of the subsurface, enhancing understanding, analysis, and decision-making for Earth system representation. We discuss the significant contributions made, the challenges encountered, and future directions for AI-empowered modeling and real-time data assimilation in achieving a truly dynamic and comprehensive Geological Digital Twin.
