Relative vs absolute dating for kids

They would all have fitted nicely into the field relationships that he had observed and his interpretation of them.

And, of course, the reported error ignores the huge uncertainties in the Creationist physicists point to several lines of evidence that decay rates have been faster in the past, and propose a pulse of accelerated decay during Creation Week, and possibly a smaller pulse during the Flood year. He may suggest that some of the chemicals in the rock had been disturbed by groundwater or weathering.

What would our geologist think if the date from the lab were less than 30 million years, say 10.1 ± 1.8 million years? Or he may decide that the rock had been affected by a localized heating event—one strong enough to disturb the chemicals, but not strong enough to be visible in the field.

Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.

These were then eroded and Sedimentary Rocks B were deposited.

It relates only to the accuracy of the measuring equipment in the laboratory.

The geologist may have found some fossils in Sedimentary Rocks A and discovered that they are similar to fossils found in some other rocks in the region.

By looking at other outcrops in the area, our geologist is able to draw a geological map which records how the rocks are related to each other in the field.In the same way, by identifying fossils, he may have related Sedimentary Rocks B with some other rocks.Creationists would generally agree with the above methods and use them in their geological work.Would he have concluded that the fossil date for the sediments was wrong? Would he have thought that the radiometric dating method was flawed? Instead of questioning the method, he would say that the radiometric date was not recording the time that the rock solidified.He may suggest that the rock contained crystals (called xenocrysts) that formed long before the rock solidified and that these crystals gave an older date.In fact, he would have been equally happy with any date a bit less than 200 million years or a bit more than 30 million years.
