Add a definition A temporal framework for pollen data is provided byradiometricdating or a stratigraphic context for the pollen-bearing sediments. From theCambridge English Corpus The large variation in degree of deformation, grade of metamorphism, andradiometricages suggest syn-spreading extensional deformation at a slow-spreading ridge. From theCambridge English Corpus From the availableradiometricdata they estimated the missing interval in the south to represent at least several million years. From theCambridge English Corpus In some cases, however, the acquisition ofradiometricdata implying later cooling and unroofing may prove the previous identification of a nonconformity to be erroneous. From theCambridge English Corpus There are data-rich compilations ofradiometricages and isotopic compositions that will be useful resources for years to come. From theCambridge English Corpus Eventually, theradiometricdata may seem to conflict with the minimum age of unroofing indicated by older nonconformable sediments. From theCambridge English Corpus Following the introduction there are three chapters devoted toradiometrictechniques, with radiocarbon covered in the greatest detail with its own dedicated chapter. From theCambridge English Corpus The pitfalls of not separating the finest and purest phases forradiometricdating are emphasized: inherited material will give 'non-metamorphic' ages. From theCambridge English Corpus Three important conclusions may be drawn from the stratigraphic andradiometricresults. From theCambridge English Corpus In such a case, the acquisition ofradiometricdata in both metamorphic units may ultimately be the only way to establish their contrasting exhumation histories. From theCambridge English Corpus As a result, the obtainedradiometricdates have no bearing on the timing of exhumation (that is, ages are underestimated). From theCambridge English Corpus They will not, therefore, be used in this present paper where more preciseradiometricages and stratigraphic correlations are needed. From theCambridge English Corpus The large variation in degree of deformation, grade of metamorphism, andradiometricages suggests syn-spreading extensional deformation at a slow-spreading ridge. From theCambridge English Corpus Short final chapters onradiometricmethods and drilling and borehole logging complete the book. From theCambridge English Corpus Traditional biostratigraphical control is usually provided by calcareous nannoplankton and foraminifers, and only a few sites have stratigraphical control through magnetostratigraphy orradiometricdating. From theCambridge English Corpus This sum gives the total photometric value of light assuming a flat electromagnetic spectrum, that is, flatradiometricspectrum. From theCambridge English Corpus Precambrian tillites generally lackradiometricage constraints sufficient for correlation of glacial episodes. From theCambridge English Corpus Initial ratios were calculated using availableradiometricages. From theCambridge English Corpus In addition to the soil background, several parameters in-uence theradiometricresponse of a plant canopy. From theCambridge English Corpus These examples are from corpora and from sources on the web.
