Knowledge graph analysis of mineralization laws research of lithium ore

As a global strategic metallic mineral resource, the scientific research, exploration, and development and utilization of lithium ore resources are important foundations for ensuring the needs of national economy and people’s livelihood. With the increasingly prominent role of lithium in national economic life, China’s investment in lithium ore investigation and research has gradually increased in recent years, accumulating a large amount of scientific research achievements in lithium ores. The study of mineralization laws is a fundamental work for evaluating the potential of mineral resources. Finding scientific methods to analyze and summarize the research results of lithium mineralization laws in recent years, sorting out the research context and hotspots, is of great significance for future lithium scientific research work deployment and mineral resource planning. This paper uses the world’s largest Chinese database CNKI as the data source, extracts and selects 196 literature materials with high relevance to the research topic in the past 30 years （1993-2022） as the research object. Using scientific knowledge graph analysis technology, knowledge graphs such as research author cooperation graph, institutional cooperation graph, keyword co-occurrence network graph and clustering graph, and theme evolution graph are drawn. Author and institution analysis, keyword co-occurrence analysis, and theme evolution analysis are carried out to scientifically summarize the current status, research hotspots, and research progress of lithium ore mineralization laws. The research results indicate that the overall trend of research on the mineralization patterns of lithium deposits is gradually increasing, and can be preliminarily divided into the exploratory development stage （1993-2015） and the rapid development stage （2016-2022）. A large amount of research work has been carried out in key areas of lithium deposit research, such as Dahongliutan, Methylka, Xinjiang, Hunan, Kerin, Northwest Jiangxi, Altai, East Qinling, and Jiulong. The research content includes the study of mineralization laws based on important elements such as mineralization indicators, mineralization models, mineralization conditions, mineralization characteristics, and mineralization epochs, as well as mineral investigation, potential evaluation, and exploration direction. The analysis method proposed in this paper is fast and effective in summarizing the research results of lithium ores, and can play a role in strategic mineral resource research.
