proposed the designation Recent for the period that has elapsed since “the earth has been tenanted by man.” It is now known that humans have been in existence a great deal longer. The preceding and substantially longer sequence of alternating glacial and interglacial ages is the .
The term Holocene was proposed in 1867 and was formally submitted to the International Geological Congress at Bologna, Italy, in 1885. Because there is nothing to suggest that the Pleistocene has actually ended, certain authorities prefer to extend the Pleistocene up to the present time; this approach tends to ignore humans and their impact, however.
Only three models fit to Glu D/L contributed to the final averaged age model.
Modeled ages ranged from 14 to 5496 years, and the median 95% confidence interval for the 54 AAR ages was ±29% of the modelled age.
Analyses of different components of the sediments show that total organic carbon ages are largely unreliable, because much of the carbon (including coal) has been transported to the bay from upstream sources and is older than sediments in which it was deposited.
Mollusk shells (clams, oysters) and foraminifera appear to give reliable results, although reworking and burrowing are potential problems.Age determination with high accuracy as well as high resolution is a principal procedure in the research of Quaternary processes, such as volcanic eruptions, lacustrine and ocean sedimentation, and recent fault activation, for investigating past global environmental changes and predicting the realistic changes in the near future.Among several dating techniques applicable to late Quaternary samples, radiocarbon dating has been commonly used since 1950, although its application is limited to ages younger than ca. In particular, recent developments of accelerator mass spectrometry (AMS)-related techniques have opened a variety of applications. *Prices in US$ apply to orders placed in the Americas only.Prices in GBP apply to orders placed in Great Britain only.The results of radiocarbon dating of coral, wood and marine mollusca from raised beaches around Taiwan indicate a regular geographic shift of Tectonic movements during the Holocene.
