摘　　要：碳酸盐晶格硫(CAS)是古环境恢复的重要手段之一,它系指在碳酸盐成岩过程中微量的硫酸盐离子取代碳酸盐离子并保存在晶格中的硫酸盐。CAS对矿物沉淀发生时的海水硫酸根的氧、硫同位素组成、硫酸盐浓度和当时古环境的氧化还原状态都有很好的保存和记录作用,因此引发了对其持续关注,并开展了一系列卓有成效的研究。本文综述了CAS当前的研究进展,主要从前处理方法、影响因素、同位素组成和古环境恢复等重点问题来探讨CAS的成因和CAS对不同沉积环境的恢复应用,并展望了需要进一步研究的几点研究方向,希望借此能引起广大研究者的兴趣和重视。Carbonate associated sulfate,or CAS in brief,is one of the important indicators for paleoenvironmental restoration.Trace sulfate may enter carbonate lattice and replaces the carbonate during diagenesis.The CAS has the capability to preserve the isotopic composition of seawater sulfate and to record the sulfate concentration of seawater,as well as the changes in the paleoenvironment.In recent years,CAS has attracted great interest and attention from the geological society.In this paper,attempt has been made to address CAS with emphases on its pre-treatment methods,influencing factors,isotopic composition and its significance in paleoenvironmental reconstruction.The application of CAS to the restoration of different sedimentary environments is discussed,in addition to the future research directions.We hope that the introduction may raise interests and attentions from researchers.
