Samples constitute a crucial component of physical geological archives. China's implementation of regional geochemical survey projects has generated massive sample collections. Statistical data indicate that the country has accumulated 9.94 million Type I and II geochemical samples, preserved in national and provincial repositories. Secondary development and utilization of these samples could facilitate the discovery of new mineral exploration clues and support green low-carbon development. However, current sample service effectiveness remains suboptimal, primarily due to the absence of standardized information collection protocols, unified publication mechanisms, and an integrated information management platform.This paper proposes an information management and service system for physical geological sample archives, structured through four hierarchical components: infrastructure layer, data resource layer, functional layer, and user interface layer. The designed system enables sample information storage, updating, and service utilization for multi-tier user groups. Its implementation aims to enhance data sharing among repository institutions at various administrative levels, improve informational management of sample resources, and promote high-quality development of physical geological archives. This system is expected to provide substantial support for China's new round of strategic mineral exploration initiatives while contributing to the advancement of sustainable resource management practices.
