Research progress and exploration application of tectono-geochemistry in the recent decade
在深部找矿需求的大背景下,构造地球化学相较于土壤、岩石地球化学在隐伏矿预测上具有天然优势,引起国内外学者研究兴趣.本文通过对构造地球化学概念、理论研究进展和勘查应用成效进行归纳总结,获得以下认识:①构造地球化学是探求构造动力与地球化学物质间内在联系的新兴交叉学科,研究物质组分在构造作用过程中的行为和结果;②构造作用控制着地质空间中物质活化的物理化学性质,驱动着构造流体中物质的迁移,最终导致元素的分异与富集;③围绕"构造驱动地球化学作用"、"地球化学诱发构造变形"、"地球化学动力学过程模拟"方面的构造地球化学研究进展明显,但"动力学机制"仍需进一步加强探索研究;④构造地球化学勘查应用的工作流程包括构造解析、构造采样、元素组合统计学分析、异常解译、成矿模型构建以及靶区圈定;⑤构造地球化学在矿床勘查方面的应用成效显著,包括Cu、Au、Pb、Zn、Ag、Mo、Sb、Sn等多金属矿床,国外学者倾向于成矿机制和成矿模型研究,而国内学者聚焦于矿体的深部预测与靶区圈定.此外,丰富深部、三维及多介质取样手段,在数据分析上借助大数据和机器学习方法,短波红外印证矿体空间分布等,均属构造地球化学勘查未来的发展趋向,研究潜力巨大,应用前景广阔.
In the context of the growing demand for deep mineral exploration,tectono-geochemistry offers distinct advantages over soil and rock geochemistry in predicting concealed orebodies,a capability that has aroused considerable research interest within the global research community.This article summarizes research progress in the concepts,theories,and exploration applications of tectono-geochemistry,yielding the following insights:① Tectono-geochemistry is an emerging interdisciplinary field that aims to explore the intrinsic relationships between tectonic dynamics and geochemistry,and to study the behavior and evolution of material components during tectonic processes.② Tectonic activity governs the physicochemical conditions for element mobilization in geological space,drives substance migration via tectonic fluids,and ultimately leads to elemental differentiation and enrichment.③ Significant research progress has been made in"tectonically driven geochemical processes,""geochemically induced tectonic deformation,"and"geochemical dynamic process simulation."However,the underlying"dynamic mechanisms"still require further exploration.④ The workflow for tectono-geochemical exploration includes tectonic analysis,structural sampling,statistical analysis of element associations,anomaly interpretation,metallogenic model construction,and target delineation.⑤ The application of tectono-geochemistry in mineral exploration has achieved remarkable results for various polymetallic deposits(e.g.,Cu,Au,Pb,Zn,Ag,Mo,Sb,and Sn).International scholars tend to study metallogenic mechanisms and models,while Chinese scholars focus on deep prediction and target delineation of orebodies.In addition,comprehensive,deep,three-dimensional,and multi-media sampling;the application of big data and machine learning methods in data analysis;and the verification of orebody spatial distribution via short-wave infrared spectroscopy are all future development trends of tectono-geochemical exploration,offering great research potential and broad application prospects.
