为深化对江南造山带金矿成矿规律的理解,进一步评估找矿潜力.本文以江南造山带及其邻区的金矿为研究对象,引入知识图谱技术,采用自上而下方法构建金矿领域知识模型,并综合利用深度学习与大语言模型构建金矿成矿‒勘查知识图谱;基于该知识图谱开展金矿社区聚类分析与Jaccard相似性评价,系统分析矿床聚集性特征.构建了含28类实体类型、10种语义关系类型的金矿领域知识模型,由此生成的知识图谱涵盖区域内60个代表性矿床,包含2 212条实体及5 497条语义关系.社区聚类分析成功提取了“蚀变‒矿物‒地层”等关键控矿要素组合及成矿规律;Jaccard系数分析显示,水口山、黄金洞金矿与世界大型‒超大型矿床具有高度相似性,揭示出两矿床具有巨大的深部及外围找矿潜力.
This study aims to deepen the understanding of metallogenic regularities and evaluate the prospecting potential of gold deposits in the Jiangnan Orogen. Focusing on the gold deposits within and adjacent to the Jiangnan Orogen, technologies related to the knowledge graph were introduced. A domain knowledge schema was developed using a top-down approach, and the metallogeny-exploration knowledge graph of gold deposits was constructed by integrating deep learning and Large Language Models (LLM). Community detection and Jaccard similarity evaluation were used to analyze the clustering characteristics of the gold deposits. The knowledge schema contains 28 geological entity types and 10 semantic relationship types. The resulting knowledge graph encompasses 60 representative gold deposits in the region, containing 2 212 geological entities and 5 497 semantic relationships. Community detection successfully extracted key ore-controlling factor combinations and metallogenic regularities, such as “alteration-mineral-strata”. Jaccard similarity analysis indicates that the Shuikoushan and Huangjindong gold deposits have high similarities to global large-to-giant deposits, revealing significant prospecting potential in their deep-seated zones and peripheral areas.
