Boreas, 28(1), 181-193
A Late Quaternary permafrost profile from the Labaz Lake area (Taymyr Peninsula, Central Siberia) has been investigated using analyses of diatoms, pollen, sedimentology and geochemistry. A sedimentation gap for the termination of the Pleistocene and the start of lacustrine sedimentation in the Borea...

A Late Quaternary permafrost profile from the Labaz Lake area (Taymyr Peninsula, Central Siberia) has been investigated using analyses of diatoms, pollen, sedimentology and geochemistry. A sedimentation gap for the termination of the Pleistocene and the start of lacustrine sedimentation in the Boreal can be inferred. At that time shallow-lake conditions prevailed and a connection to the Labaz Lake is probable. The diatom data provide indications for the assessment of the Holocene environmental development of the study site in more detail. The most favourable climatic conditions and comparatively higher water level stands are inferred for the early Atlantic. Towards the end of this period the gradual transition to a wetland with poor-fen character took place. Within the Subboreal there was a short episode with mild climate conditions. At that time the last trees occurred in the Labaz Lake area and somewhat higher water level stands were likely. The Subatlantic climate deterioration led to further drying up of the wetland along with a lowering of water pH and permafrost aggradation. The transition from a locality with low-centre to one with high-centre polygons is still underway. |
