There is growing scientific appreciation of the complexity of the Quaternary Period.

This has increased the demand on geochronological techniques to deliver increasingly more accurate and precise ages, which underpin attempts to determine the causes and consequences of events at a variety of temporal and spatial scales.

the intersection between the wave cut platform and the former cliff), an uncertainty of 3m is usually attributed to it as a sea level indicator.

If the inner margin is masked by subsequent marine or continental deposition, it is evidenced by a break in slope, and the uncertainty associated to the past sea level is higher.

Read more is an international journal devoted to the publication of the highest-quality, peer-reviewed articles on all aspects of dating methods applicable to the Quaternary Period - the last 2.6 million years of Earth history.

These features are usually divided into two categories: Type A are sloping shore platforms, that slope gently between about 1° and 5°; and Type B are horizontal shore platforms, are found where waves have exposed the surface of a flat or gently dipping resistant rock formation, usually a bedding plane.

There are three standard creationist responses: First, creationists assert that current rates (Y) are different than past rates.

It is possible that these rates changed — but under uniformitarianism, which is necessary for science to function, we must assume that rates did not change unless there is evidence for this change.

From this limited amount of information, and through assumptions about the accumulation history (sedimentation rate, hiatuses), the ages of all depths of a core need to be estimated somehow (age-depth modelling).

C atom will disappear cannot be predicted; it could happen within a few seconds, but it could also survive several tens of thousands of years.
