摘要

来自中欧的Eemian花粉记录描述了从早期Eemian的嗜热树木分类群到晚期Eemian北方树木分类群的转变,随后的草原上有森林开放。Eemian中后期转变的可用夏季温度重建显示,在这段时间内,温度值呈下降趋势。我们提出了一个来自德国南部的新的指压学记录,该记录涵盖了从伊米安中期到第一个维尔米安体育场(约125-105年 ka),以及早期Würmian冰川作用的晚期Rissian冰川作用和早期Brörup中间层的一部分。根据这一记录,我们描述了前Füramoos古湖的湖泊发育,并定量重建了所检查区间内7月的气温。晚里希阶沉积物主要由两个摇蚊分类群组成,即Sergentia coracina型和Microsectra radialis型,表明条件非常寒冷。在一个不确定的时间间隔之后,可能包括在晚里斯期/伊米安过渡期的间断,伊米安中期的沉积物含有玻璃质Tanytarsus型和门达克斯Tanytarsu型,这表明7月的气温相对较高。在Eemian晚期,典型的嗜热类群,如Tanytarsus glabrescens型消失,表明温度下降。Stadial A与pedellus型小卷须的增加有关,表明存在更多的寡营养条件。早期的Brörup沉积物含有Tanytarsus glabrescens型,表明7月份的气温略有上升。重建后的七月气温显示温度为7-8 晚里斯期为°C,从约15.5–12下降 Eemian中后期的°C,与北半球7月日照减少有关。七月气温值在12到14之间变化 Eemian晚期的°C,而重建的温度保持在12–13.5之间 Stadial A期间的°C。我们新的基于指压学的温度重建为从伊米安中期到Brörup中期的温度发展以及从德国南部高山前陆到晚里斯阶的部分温度发展提供了有价值的确证和新的量化。

Chironomid-inferred summer temperature development during the late Rissian glacial, Eemian interglacial and earliest Würmian glacial at Füramoos, southern Germany

Chironomid-inferred summer temperature development during the late Rissian glacial, Eemian interglacial and earliest Würmian glacial at Füramoos, southern Germany

Eemian pollen records from central Europe describe a transition from thermophilous tree taxa in the early Eemian to boreal tree taxa in the late Eemian with forest opening in the subsequent stadial. Available summer-temperature reconstructions for the mid- to late Eemian transition show decreasing values during that time. We present a new chironomid record from southern Germany that covers the mid-Eemian to the end of the first Würmian stadial (c. 125–105 ka) and also parts of the late Rissian glaciation and early Brörup interstadial of the early Würmian glaciation. Based on this record we describe lake development in the former Füramoos palaeolake and quantitatively reconstruct July air temperature during the examined interval. Late Rissian sediments are dominated by two chironomid taxa, Sergentia coracina-type and Micropsectra radialis-type, indicating very cold conditions. Following an uncertain interval, probably including a hiatus at the late Rissian/Eemian transition, mid-Eemian sediments contain Tanytarsus glabrescens-type and Tanytarsus mendax-type suggesting relatively high July air temperatures. During the late Eemian, typically thermophilic taxa such as Tanytarsus glabrescens-type disappear, suggesting decreasing temperatures. Stadial A is associated with increases in Microtendipes pedellus-type suggesting more oligotrophic conditions. Early Brörup sediments contain Tanytarsus glabrescens-type, suggesting a slight increase in July air temperature. Reconstructed July air temperatures show temperatures of 7–8 °C during the late Rissian and a decline from ~15.5–12 °C during the mid- to late Eemian associated with decreasing Northern Hemisphere July insolation. July air temperature values vary between 12 and 14 °C in the late Eemian, while reconstructed temperatures remain within 12–13.5 °C during Stadial A. Our new chironomid-based temperature reconstruction provides valuable corroboration and new quantification of temperature development from the mid-Eemian to the early Brörup interstadial as well as for sections of the late Rissian from the alpine foreland of southern Germany.

期刊介绍: Boreas has been published since 1972. Articles of wide international interest from all branches of Quaternary research are published. Biological as well as non-biological aspects of the Quaternary environment, in both glaciated and non-glaciated areas, are dealt with: Climate, shore displacement, glacial features, landforms, sediments, organisms and their habitat, and stratigraphical and chronological relationships. Anticipated international interest, at least within a continent or a considerable part of it, is a main criterion for the acceptance of papers. Besides articles, short items like discussion contributions and book reviews are published.
