Optical dating techniques
Recently, underestimation of OSL ages has been reported for quartz when samples with expected age older than about 70 ka are dated.Infrared stimulated luminescence (IRSL) signal of feldspars saturates at much higher dose than quartz and therefore holds a potential for dating loess deposited before the Late Pleistocene.
The heating must have taken the object above 500° C, which covers most ceramics, although very high-fired porcelain creates other difficulties.
A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved.
However, by itself a fossil has little meaning unless it is placed within some context.
Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.
A few examples of such lies are presented at the very bottom of this page.

However, feldspars are not commonly used for dating due to the observed instability of the IRSL signals which could lead to severe age underestimation.
