Analysis of trajectories and developmental prospects of research on carlin-type gold deposits on the basis of big data community detection algorithms
Bibliographic record
Abstract
• Pioneering Methodology: Applies graph-based community detection (CiteSpace) to map the 56-year knowledge trajectory and developmental prospects of Carlin-type gold deposit research, overcoming limitations of traditional reviews. • Theoretical Advancement: Proposes the universally applicable “multi-source fluids – tectonic activation – nano-scale occurrence” system and the spiral cognitive model (phenomenon → mechanism → system → prediction), extending relevance beyond Carlin-type deposits. • Actionable Pathways: Provides technology-driven solutions (multiscale characterization, AI-enhanced prospecting, eco-extraction) and global collaboration frameworks to address challenges in reserve expansion, sustainable extraction, and theory refinement. The rise of big data analytics and knowledge graph technology has introduced a new paradigm for research on mineral deposits. This study employs CiteSpace, a graph-based community detection tool, to analyze the Web of Science Core Collection literature (1969–2025) on Carlin-type gold deposits, with the aim of identifying global research trajectories, collaboration networks, key themes, frontiers, and future directions. The evolution of research encompasses five distinct phases: the Foundational Period (1969–1990), Domain-expanding Period (1991–2000), Refinement Period (2001–2010), Integration Period (2011–2020), and the ongoing Transformative Leap Period (2021–2025). Geographically, studies have expanded from their origin in Nevada, U.S., to a global scale. Methodologically, advancements have progressed from macro-geological mapping to atomic-scale characterization, accompanied by a theoretical shift towards an integrated “multi-source fluids – tectonic activation – nano-scale occurrence” system. This progression follows a spiral cognitive model: phenomenon description → mechanism analysis → system modeling → predictive application. The international collaboration network has evolved into a “dual-core leadership with multi-tier synergy” framework, where core nations (China and the U.S.) drive cutting-edge theoretical exploration by leveraging their giant ore clusters, while secondary nodes (e.g., Canada, Iran, Australia) enhance research scope and depth through critical regional analogues and cross-deposit-type expertise. Emerging participants (e.g., Malaysia) inject new dynamism and alternative genetic perspectives. Research leadership has transitioned from early dominance by U.S. institutions (e.g., USGS) to prominence of Chinese entities (e.g., Chinese Academy of Sciences, China University of Geosciences) post-2010. Core research themes include: (1) ore formation-regional tectonic coupling, (2) ore-forming fluid dynamics, (3) microscopic gold occurrence and mineralization processes, (4) resource utilization challenges, and (5) integration of multi-technique methodologies and intelligent exploration. Current research frontiers focus on: metallogenic chronology and geodynamic settings, multi-source fluid evolution and tectonic-lithologic coupling, invisible gold occurrence mechanisms, exploration technology innovation and deep targeting, and integrated studies across diverse deposit types. Future priorities center on two pillars: (1) Technological innovation: integrating techniques such as APT, NanoSIMS, and in situ isotopic methods for “atom-mineral-deposit-region” multiscale modeling; applying machine learning to overcome deep-prediction bottlenecks for intelligent “geology-geochemistry-geophysics-remote sensing” prospecting; and developing eco-leaching/microbial oxidation processes for the efficient extraction of gold and associated critical elements (As, Sb, Hg, Fe, S) from refractory ores. (2) International collaboration: establishing unified deposit testing standards; creating a global data-sharing platform; and deepening strategic partnerships through core-core, core-secondary, and core-emerging nation collaborations. These coordinated advancements are poised to drive breakthroughs in reserve expansion, extraction efficiency, sustainable resource development, and the refinement of metallogenic theory

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
