Radiometric in a sentence

Accuracy of radiometric dating Thermal ionization mass spectrometer used in radiometric dating.

Modern radiometric dating Radiometric dating continues to be the predominant way scientists date geologic timescales.

Helicopter-borne aeromagnetic, horizontal gradiometric, radiometric, and VLF-EM surveys covered a total of 7,117 line kilometers at 50-meter line spacing.

However, no follow-up electromagnetic ("EM") work was carried out over the radiometric anomaly beyond the VLF component of the historical airborne survey, which had a limited depth of investigation.

Figure 1. Map showing radiometric anomalies within the Mkuju Project and targets/deposits that will be drilled.

Gravity, magnetic and radiometric data are being analyzed to assist with pinpointing the highest priority drill locations along the EM conductors for drilling.

In the 19th century, discoveries of fossils and the later invention of radiometric dating demonstrated that the Earth is billions of years old, debunking Ussher’s timeline.

With support from the World Bank, the first nationwide airborne geophysical survey has been completed, to provide high resolution magnetic and radiometric data on Sierra Leone's mineral assets and deposits.

The ministerial department clarifies that occurrences detected by the Modis (Moderate Radiometric Image Definition Spectrum) satellite can lead to an exaggeration of the situation and misinform the most unwary.

Analysis of the relative concentrations of various uranium, thorium and protactinium isotopes in water and minerals is used in radiometric dating of sediments which are up to 175,000 years old and in modeling of various geological processes.

Another method of specifying spectral width is a special case of root-mean-square deviation where the independent variable is wavelength, λ, and f (λ) is a suitable radiometric quantity.

A radiometric age for the Cretaceous-Tertiary boundary based on K-Ar, Rb-Sr, and U-Pb ages of bentonites from Alberta, Saskatchewan, and Montana.

Arthur Holmes establishes radiometric dating Although Boltwood published his paper in a prominent geological journal, the geological community had little interest in radioactivity.

Boltwood gave up work on radiometric dating and went on to investigate other decay series.

Detection and measurement The ionizing or excitation effects of beta particles on matter are the fundamental processes by which radiometric detection instruments detect and measure beta radiation.

During six flybys of Titan from 2006 to 2011, Cassini gathered radiometric tracking and optical navigation data from which investigators could roughly infer Titan's changing shape.

Estimates varied from a few hundred thousand to billions of years. citation By the early 20th century, radiometric dating allowed the Earth's age to be estimated at two billion years.

Fossil discoveries and radiometric dating in the last quarter of the 20th century have called these dates into question.

Holmes, being one of the few people on Earth who was trained in radiometric dating techniques, was a committee member, and in fact wrote most of the final report.

However, Strutt's student Arthur Holmes became interested in radiometric dating and continued to work on it after everyone else had given up.
