Petrology and mineralogy are important branches of Earth science, and related research can provide in-depth understanding of important scientific issues such as planetary formation and evolution, resource enrichment and environmental changes on habitable Earth. Journal of Petrology and Mineralogy is an important domestic journal in the field of petrology and mineralogy. In-depth exploration of the articles published in the journal helps to sort out research progress and provide background information for discipline practitioners to conduct further research. This can also provide reference for the journal’s future direction of publication. This paper conducts quantitative research on the literature published in the Journal of Petrology and Mineralogy from 1982 to 2022 using big data analysis, machine learning, and visualization technologies. The research found that petrology and mineralogy have always been the main focus of the journal, and “geochemistry, granite, zircon U-Pb dating, adsorption, and mineralogy” are hot Keywords. Among them, “geochemistry” has the highest co-occurrence intensity, closely related to Keywordssuch as granite, rock genesis, volcanic rocks, and petrology; followed by lattice parameters, with relevant Keywordssuch as optical properties, powder diffraction data, and new minerals. The specific research topics include four different themes, such as metamorphic mineral formation and new mineral discoveries, characteristics of mineral deposits and ore-forming mechanisms, volcanic rock genesis, surface processes, and rock genesis and tectonic background. Future publications encourage the development and application of new technologies and methods, interdisciplinary research, and new paradigm research driven by big data and machine learning.
