| Zusammenfassung |
| Studies on the formation of the ancient Diexi barrier lake on the
Mingjiang River, southwestern China, have long been carried out.
However, investigations into the correlation between the
palaeoclimate and palaeoenvironment and the palaeoseismic events in
this area are rarely found in literature. The present study took
sediments from the ancient Diexi barrier lake to investigate the
palaeoclimate, palaeoenvironment and palaeoseismic events. A drilling
at the centre of the barrier lake was conducted and the core of
about 260 m long was examined. The palaeoclimate and
palaeoenvironment indicators (sporopollen, carbon and oxygen
isotopes, organic matter, calcium carbonate, granularity) from the
sediments have been tested and analysed, and indicate that there
were 10 climatic and environmental periods between
30 000 and 15 000 a BP (before present). The discovered disturbance
segments in the core indicate there were at least 10 seismic events
during that period. The consistency between climate change and
seismic events indicates that a strong seismicity is normally
accompanied by a climatic variation. This may be a useful
supplement for climate and geohazard predictions in the future. |
