How old is the earth based on radiometric age dating
The abundance and variety of fossils in Phanerozoic rocks have allowed geologists to decipher in considerable detail the past 600 million years or so of the Earth’s history.
With the development of modern radiometric dating methods in the late 1940s and 1950s, it was possible for the first time not only to measure the lengths of the eras, periods, and epochs but also to check the relative order of these geologic time units.
Radiometric dating verified that the relative time scale determined by stratigraphers and paleontologists (Figure 1) is absolutely correct, a result that could only have been obtained if both the relative time scale and radiometric dating methods were correct.
Thus, the radiometric ages obtained from these oldest rocks are not necessarily the age of the first event in the history of the rock.
Moreover, many of the oldest dated rocks intrude still older but undatable rocks.
Three basic approaches are used to determine the age of the Earth.
The first is to search for and date the oldest rocks exposed on the surface of the Earth.
efore analyzing the arguments advanced by creation “scientists” for a very young Earth, I here summarize briefly the evidence that has convinced scientists that the Earth is 4.5 to 4.6 billion years old.
There can be no doubt about the Earth’s antiquity; the evidence is abundant, conclusive, and readily available to all who care to examine it.
Literally many tens of thousands of radiometric age measurements are documented in the scientific literature.Tags: Adult Dating, affair dating, sex dating
