dating

In geology, the process of determining the age of minerals, rocks, fossils, and geological formations. There are two types of dating: relative and absolute. Relative dating involves determining the relative ages of materials, that is determining the chronological order of formation of particular rocks, fossils, or formations, by means of careful field work. Absolute dating is the process of determining the absolute age (that is the age in years) of a mineral, rock, or fossil. Absolute dating is accomplished using methods such as radiometric dating (measuring the abundances of particular isotopes in a mineral), fission track dating, and even counting annual layers of sediment.

If the caligraphy be Poe's, it is different in all essential respects from all the many specimens known to us, and strongly resembles that of the writer of the heading and dating of the manuscript, both of which the contributor of the poem acknowledges to have been recently added.

When they have visions of scenes they have never seen in the flesh, memories of acts and events dating back in time, the simplest explanation is that they have lived before.

We could recognize the Tower of Hippicus, the Mosque of Omar, the Damascus Gate, the Mount of Olives, the Valley of Jehoshaphat, the Tower of David, and the Garden of Gethsemane--and dating from these landmarks could tell very nearly the localities of many others we were not able to distinguish.
