文摘
- •
Distribution of branched GDGTs in lake differed from that of soils around the lake.
- •
The MBT and CBT values in lake and soils varied in different ranges.
- •
The maximum concentration and flux of branched GDGTs occurred during winter time.
- •
In situ production of branched GDGTs mainly in deep part of the lake
- •
Branched GDGTs can be used as proxies for mean annual air temperatures in HML.
