摘    要:同位素地质年代学为地球与行星科学研究提供时间坐标,厘定深时地质过程发生和持续的时间,从而为不同地质作用的因果联系和协同演化提供定量制约。新世纪以来,在以EARTHTIME为代表的地质年代学共同体努力下,同位素地质年代学在高精度、高空间分辨率和高效率等维度取得长足进步,与其他学科的结合也更加紧密深入。结合正在兴起的相对定年技术和年代学大数据等,我们得以从更精细、更全面的视角来理解地质作用的全过程。展望未来,持续发展与革新的同位素地质年代学将继续为地球与行星科学研究提供关键支撑,服务于深地、深海、深空和地球系统科学等国家战略、国民经济主战场和科学前沿。

关 键 词:深时  高精度  高效率  高空间分辨率  相对定年

Abstract:Radiometric geochronology is an essential component of Earth and Planetary Sciences, which provides time- coordinates to establish timelines and timescales of geological events, and ultimately facilitates a robust understanding on causality and co- evolution of these events. Accelerated by community driven initiatives such as EARTHTIME, significant advances were achieved in geochronology in the last two decades, as represented by improvements in precision, spatial resolution and efficiency. Along with breakthroughs in relative dating techniques and big data, innovations in geochronology enable a more comprehensive understanding on a variety of geological processes when state- of- the- art geochronology is integrated with robust geological frameworks. In the upcoming future, we are confident that geochronology will continually serve Earth and Planetary Sciences and beyond.
Keywords:deep time  high precision  high efficiency  high spatial resolution  relative dating
