摘要
X射线计算机断层成像(X-ray computed tomography,X-CT)技术以其无损、高效、高分辨率和多尺度三维成像等独特优势,在地质学研究中扮演着重要的角色。当前,X-CT技术在地质学研究领域应用的相关综述文献仍较为匮乏,且已有的综述文章在内容关联性和系统性方面尚存在改进空间,未能充分反映X-CT技术的日益发展及其在地质学研究中应用领域不断扩展的事实。为此,文章较全面地回顾并总结了国内外X-CT技术在地质学研究中的应用现状。首先,从内容连贯性和体系性的角度出发,对X-CT技术的发展史、基本原理、优劣势等做了基本的回顾;其次,从地球演化的宏观视角切入,聚焦于地球的形成、地球内部深处物质(如熔体、岩浆)和浅部物质(与风化、沉积、变质变形等过程相关的地质材料)的结构及其变化,详细探讨了X-CT技术在地质学各分支学科中的应用实例和最新进展;最后,对全文做出归纳,并对X-CT技术未来的发展趋势进行了预测。总体而言,随着X-CT技术在地质学研究中的深度应用,地质学家对于地球的起源、物质构成及演化历程等核心议题的认识正日益深化,这将有力推动地球科学研究的整体进步。
X-ray computed tomography(X-CT)technology stands out for its non-destructive,rapid,high-resolution,and multi-scale three-dimensional imaging capabilities,playing an important role in geological re-search.Presently,there is a scarcity of comprehensive review literature on the application of X-CT technology in geology,and existing review articles often lack adequate consideration for content relevance and systematic ar-rangement,failing to fully reflect the growing development of X-CT technology and its expanding scope of appli-cation in geological studies.To address this gap,this article provides an overview of the current status of X-CT technology utilization in geological research both domestically and internationally.To better ensure coherence and systematics of the content,the article begins by revisiting the historical development,fundamental principles,ad-vantages,and disadvantages of X-CT technology.Subsequently,starting from various levels of evolution of the Earth,including the formation of the Earth,the structure and changes of deep-seated materials(such as melts and magma),and the structure and alterations of shallow Earth materials(involving to processes like weathering,sedi-mentation,metamorphism and deformation),the paper discusses the status of X-CT technology applications in ge-ology.Finally,the paper concludes with a summary and an outlook on the future development of X-CT technolo-gy.Overall,as X-CT technology becomes increasingly involved,geologists will have multi-level understanding on the origin,composition,and evolutionary processes of the Earth,which contributing to the advancement of the entire field of Earth sciences.
