花岗岩系统科学的兴起:21世纪技术革命驱动的理论重构与学科拓展OA

Entering the 21st century,propelled by technological advances and growing societal demands,granite research is undergoing a significant transition—from traditional,static petrology to a new paradigm of"Granite System Science",centered on precess analysis,system coupling,and trend forecasting.Withn this framework,granitic magma system is viewed as a complex system that spans the entire crust and coevolves through multiphase,multiscale,and multiphysical-chemical processes.It not only preserves the spatiotemporal record of deep crustal evolution but also plays a key regulatory role in the transfer and redistribution of energy and matter.Technological progress has reshaped the boundaries of granite research.Multi-scale observations enabled by micro-analytical techniques and high-resolution geophysical imaging,combined with the deep integration of high-P-T experiments,numerical simulations,machine learning,and geo-big-data analytics,have driven the discipline beyond"reconstructing the past"toward"simulating processes"and"predicting the future,"making granite systems increasingly visualizable,computable,and predictable.Theoretically,the dynamic mush system has emerged as the central concept for reconstructing granite-forming processes.When magma enters a crystal-dominated mush regime,melt and volatiles undergo efficient differentiation through reactive flow,compaction-induced extraction,and channelized migration,establishing a multi-scale coupled dynamics of melt-crystal-fluid(volatile)interactions.This model demonstrates that:(1)large granitoid batholiths are assembled incrementally over millions of years through multiple magma pulses;(2)most plutons consist of cumulate residues left after the extraction of high-silica interstitial melts from long-lived mush systems,mixed with materials delivered by late-stage replenishing magmas;(3)extreme enrichment of rare metals results from late-stage melt-fluid immiscibility and volatile concentration;(4)volcanic eruptions are modulated by the development of critical melt-rich zones and volatile accumulation within mush bodies;and(5)deep mush systems,together with trans-crustal magma plumbing and volcanic edifices,form an integrated mass-and-energy transport network that shapes carbon cycling,silicate weathering,and subduction processes,and may ultimately drive climatic perturbations and biological evolutionary events.In practical applications,Granite System Science is becoming an essential geoscientific foundation for energy transition,resource security,and climate-change mitigation.Its concepts and methodologies support exploration of critical minerals,geothermal energy development,geological CO2 storage,enhanced weathering for carbon removal strategies,nuclear waste isolation,and deep underground space utilization.It also provides a new comparative perspective for understanding planetary crustal evolution and resource potential on other celestial bodies.Overall,the rise of Granite System Science reflects a paradigm-shift trajectory driven by societal needs,technological innovation,theoretical reconstruction,and disciplinary expansion.It signals the entry of Earth sciences into a quantitative era grounded in system integration and process simulation,with enhanced capacity for predicting the unknown and exploring future scenarios.This emerging framework offers new theoretical platforms and research pathways for advancing our understanding of mantle-crust material cycling,crustal evolution,the carbon cycle,and the Earth's climate system.
