Principles of radiometric dating
Creationist researchers don’t fully understand yet. The decay rate varied based on the stability or instability of the parent atoms. Look again at Figure 1, which is a geologic diagram depicting the rock layers in the walls of the Grand Canyon, along with the rock units deep in the inner gorge along the Colorado River.This diagram shows that the radiometric dating methods accurately show the top rock layer is younger than the layers beneath it.So accordingly all four dated rock units () are also Precambrian.
This is considered an unnecessary waste of time and money.Based on the radioactive clocks, we can conclude that these four rock units deep in the gorge () are all older in a relative sense than the horizontal sedimentary layers in the Canyon walls.Conventionally the lowermost or oldest of these horizontal sedimentary layers is labeled early to middle Cambrian3 and thus regarded as about 510–520 million years old.4 All the rocks below it are then labeled Precambrian and regarded as older than 542 million years.Radiometric dating methods sometimes yield conflicting results, but the technique itself is scientific and reliable, and once the results are interpreted in a biblical framework, they yield clear patterns that help us better understand the earth’s history since creation six thousand years ago.PART 1: Radiometric Dating: Back to Basics PART 2: Radiometric Dating: Problems with the Assumptions PART 3: Making Sense of the Patterns This three-part series will help you properly understand radiometric dating, the assumptions that lead to inaccurate dates, and the clues about what really happened in the past.
