Sentence examples for methods of radiometric from inspiring English sources

Other professors have issued long tracts comparing the various methods of radiometric dating and showing that they all agree: The earth is over four billion years old.

Additional methods of radiometric dating that followed revolutionized estimates of the age of Earth and proved invaluable in archaeology.

In this paper, a new method of radiometric quality assessment of digital images acquired from low altitudes is presented.

The assemblage is easily dated because it contains many fine ash-beds, which are a good source of zircons used in the uranium-lead method of radiometric dating.

By means of radiometric methods such as gamma spectroscopy (or a method using a chemical separation followed by an activity measurement with a non-energy-dispersive counter), it is possible to measure the concentrations of radioisotopes and to distinguish one from another.

Prior to the development of radiometric methods of dating rocks, the ages of rocks and other geologic features could not be expressed quantitatively, or as numbers of years, but instead were expressed solely in terms of relative ages, in which the age of a particular geologic feature could be expressed as relatively younger or older than other geologic features.

Such arguments have been dismissed by scientists on the grounds that independent methods have confirmed the reliability of radiometric dating as a whole; additionally, different radiometric dating methods and techniques have independently confirmed each other's results.

The proposed method comprises two variants of radiometric correction, each of these depending on the quality of the pictures.

With the advent of radiometric dating methods, absolute ages for various periods can be determined.

In turn, the development of radiometric dating methods has permitted numerical estimates of age to be incorporated in the scale of geologic time.
