| A geologic time scale combines absolute age determinations, in years, with relative age based on sequences of rock strata. |
|
| Prior to the advent of radionuclide methods for absolute age dating, there were available relative methods of deciding when a formation was deposited prior to others. |
|
| The samples were dated in terrestrial laboratories using radioactive decay, and the relation between absolute age in years and crater density was established. |
|
| A method is discussed whereby an absolute age is determined from the disintegration products of uranium introduced into fossil bones by solutions. |
|
| Locally, some index fossils can be correlated with absolute age dates that are slightly older or slightly younger than the upper and lower age limit of the time slice. |
|
| But once they had the rocks in hand, they could determine their absolute age in years. |
|
| Thus, 88 is the absolute age record for reappointment of a former staff member. |
|
| Doug H Sanders. Keegan Bradley takes an absolute age to play his second shot. |
|
| The absolute age of the granitic rocks at Mount Pleasant, collectively referred to as Mount Pleasant Porphyry, is uncertain. |
|
| It allows to determine the absolute age or time elapsed since the death of the material. |
|
| Lawyers said there was no absolute age when children were considered able to make decisions like whether they would seek asylum. |
|
| As it was from a kick, the scrum goes Quins' way, but Monye did have an absolute age on the ball. |
|
| Chronostratigraphy is the branch of stratigraphy that places an absolute age, rather than a relative age on rock strata. |
|
| The Triassic System is dominated by sedimentary rocks, which, unlike igneous rocks, generally do not yield reliable radiometric data, which are used to establish absolute age. |
|
| Our simple 'Green Packaging' also removes the sheer frustration of trying to get into your item as it doesn't leave you for an absolute age trying to get into your brand new goods through all that card and plastic! |
|
| Geologists also use methods to determine the absolute age of rock samples and geological events. |
|
| Blimey both national anthems took an absolute age. |
