湖泊年纹层研究进展与展望
Progress and Prospects of Lacustrine Varve Research
摘要
Abstract
[Significance]As a high-resolution geological record with seasonal to inter-annual time scales,the lacus-trine varves play an essential role in paleoclimatic and paleoenvironmental research.[Progress]In this review,we summarized the formation and preservation of lacustrine varves,their identification and classification,varve chronol-ogy,anf their implications for paleoclimatic and paleoenvironmental changes.Our findings reveal that(1)the forma-tion and preservation of lacustrine varves are influenced by seasonal paleoclimatic and paleoenvironmental changes and are mainly distributed in high-latitude areas of the Northern Hemisphere;(2)the geophysical,geochemical,and geobiological features,or cross-validation of other radiometric dating methods,are necessary to verify the annual nature of the varves;(3)lacustrine varves can be used to establish accurate or floating geochronologies;and(4)la-custrine varves have been used to reconstruct paleoclimatic and paleoenvironmental changes,but research on lacus-trine varves is unevenly distributed,with a temporal focus on the Quaternary and a spatial focus on Europe and Amer-icas.[Conclusions and Prospects]Based on current progresses and problems in lacustrine varve research,future at-tention should be paid to:(1)strengthen modern sediment monitoring and optimize the identification criteria;(2)systematically construct and improve the research system of lacustrine varves with multiple research approaches;and(3)dig deep into the deep-time lacustrine varves and focus on frontier scientific issues such as annual and inter-annual paleoclimate change.关键词
