Item #: SCP-1050 Object Class: Safe Special Containment Procedures: SCP-1050-1 is to be maintained in a storage facility with interior dimensions of at least five (5) meters by five (5) meters by thirty-two (32) meters. The ceiling of the storage facility, specifically the area directly over SCP-1050-1, must be shielded to block radio waves broadcast at an intensity of [REDACTED]. Occurrences of SCP-1050-2 are to be located upon identification of the corresponding change in SCP-1050-1. In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the oldest and the most recent possible moments when an event occurred or an artifact was left in a stratum.But this method is also useful in many other disciplines.The hydration rate is typically established empirically through the calibration of measured samples recovered in association with materials whose cultural age is known or whose age can be radiometrically determined, usually through radiocarbon dating methods (Meighan 1976).
Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.
Once a hydration layer has been measured, it can be used to determine the relative ages of items or, in some circumstances, can be converted into an estimated absolute age.
In order to transform the hydration rim value to a calendar age, the rate of the diffusion of water into the glass must be determined or estimated.
Furthermore, useful fossils are either rare or totally absent in rocks from Precambrian time, which constitutes more than 87 percent of Earth history.
Precambrian rocks must therefore be correlated by means of precise isotopic dating.
