Do geologists use radiometric dating

Another method is to make age measurements on several samples from the same rock unit.

This technique helps identify post-formation geologic disturbances because different minerals respond differently to heating and chemical changes.

The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.

Technical details on how these dates are calculated are given in Radiometric dating. As with any experimental procedure in any field of science, these measurements are subject to certain "glitches" and "anomalies," as noted in the literature.

Over a thousand papers on radiometric dating were published in scientifically recognized journals in the last year, and hundreds of thousands of dates have been published in the last 50 years.

Essentially all of these strongly favor an old Earth.

The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.

Vast amounts of data overwhelmingly favor an old Earth.

147] has highlighted the fact that measurements of specimens from a 1801 lava flow near a volcano in Hualalai, Hawaii gave apparent ages (using the Potassium-Argon method) ranging from 160 million to 2.96 billion years, citing a 1968 study [Funkhouser1968].

In the particular case that Morris highlighted, the lava flow was unusual because it included numerous xenoliths (typically consisting of olivine, an iron-magnesium silicate material) that are foreign to the lava, having been carried from deep within the earth but not completely melted in the lava.

Several hundred laboratories around the world are active in radiometric dating.

Their results consistently agree with an old Earth.Some [skeptics] make it sound like there is a lot of disagreement, but this is not the case.
