文摘 古海洋微量元素地球化学循环、沉积环境和生物发育之间发生着复杂的相互作用,对重要地质事件具有指示意义.为加深对这一领域的认识,本文综述了微量元素在古环境重建及在关键地质事件的地球化学应用研究进展.以我国华南地区震旦系-下寒武统为例,阐述了关键地质事件时期古海洋中微量元素变化、沉积环境演变和生物演化之间的协同机制.指出今后值得进一步从微量元素同位素以及不同盆地乃至全球尺度上对比探讨震旦系-早寒武世沉积地层中微量元素分布特征及其在寒武纪生物大爆发中的响应.
其他语种文摘 The complicated interactions among the geochemical recycling of trace elements,sedimentary environment,and biological development of paleo-oceans are of indicative significance to key geological events. In order to deepen the understanding of this topic,the research progress about the geochemical applications of trace elements for reconstructing paleoenvironment and for studying key geological events has been reviewed in this paper. Taking the Sinian-Lower Cambrian strata in South China as objectives of a case study,we have deeply discussed the co-evolution mechanisms among the trace elements distribution patterns,variation of sedimentary environments,and the biological development. The comparative study on distribution characteristics of trace elements and isotopes of the Sinian-Early Cambrian strata and their possible implications for studying the Cambrian Biomass Explosion from perspectives at a basin or even a global scale are worth to be further comprehensively undertaken in near future.
