Speleothem archives and the Anthropocene

摘要：

Consideration is being given to defining a new Anthropocene epoch,starting in the mid-20th century.Geochemicalmarkers are likely to be crucial in defining the boundary and include radiogenic isotopes,organic pollutants and N and Sspecies.A sub-set of these geochemical parameters can be determined in archives of speleothems(calcareous cavedeposits).The concept of the Anthropocene also draws attention to the human-modified nature of modern environmentsthat are monitored to serve as modern analogues for palaeoenvironmental archives.Thus,modern cave environments,and the surface environments that they indirectly characterize,can be modified in a variety of ways from their naturalcondition.
