accuracy ultrasound dating conception - Geological time and radiometric dating

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.

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 isochron techniques are partly based on this principle.

The use of different dating methods on the same rock is an excellent way to check the accuracy of age results.

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

Their results consistently agree with an old Earth.

The differences actually found in the scientific literature are usually close to the margin of error, usually a few percent, not orders of magnitude!

Vast amounts of data overwhelmingly favor an old Earth.

Some [skeptics] make it sound like there is a lot of disagreement, but this is not the case.
