资源简介:
In a borehole in the southern outskirts of the town of Göttingen, limnic sediments of several Pleistocene warm periods occur intercalated with coarse solifluction debris and gravel of the river Leine.
Pollen analysis of the limnic sediments in a borehole at Ottostrasse gave evidence of three warm periods of interglacial character, followed by three interstadial phases. The warm phases are separated one from another by stadial phases with, at least in one case, indications of periglacial solifluction. This sequence belongs to the Brunhes magnetic epoch. The pollen data allow to exclude an Eemian or Holsteinian age of the warm period sediments. Thus a Cromerian age is assumed, though the exact position of the newly described warm periods within the ''Cromerian'' remains uncertain. […]
在哥廷根镇南郊的一处钻孔中,多层更新世暖期湖相沉积物(limnic sediments)与粗粒融冻泥流(solifluction)碎屑及莱讷河(Leine)砾石互层产出。
奥托大街(Ottostrasse)处钻孔内的湖相沉积物孢粉分析(pollen analysis)提供了三期具有间冰期性质的暖期存在的证据,其后伴随三期间冰阶(interstadial phases)。各暖期之间以冰阶(stadial phases)相隔,其中至少有一期存在冰缘(periglacial)融冻泥流的相关证据。该沉积序列隶属于布容磁性期(Brunhes magnetic epoch)。孢粉数据可排除该暖期沉积物属于埃姆间冰期(Eemian)或霍尔斯坦间冰期(Holsteinian)的可能性。因此推测其为克罗默尔冰期(Cromerian)沉积,尽管本次新描述的暖期在"克罗默尔冰期"内的确切位置仍未明确。[…]
