Christian response carbon dating
No matter what the radiometric date turned out to be, our geologist would always be able to ‘interpret’ it.He would simply change his assumptions about the history of the rock to explain the result in a plausible way. Wasserburg, who received the 1986 Crafoord Prize in Geosciences, said, ‘There are no bad chronometers, only bad interpretations of them!Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.These were then eroded and Sedimentary Rocks B were deposited.From his research, our evolutionary geologist may have discovered that other geologists believe that Sedimentary Rocks A are 200 million years old and Sedimentary Rocks B are 30 million years old.Thus, he already ‘knows’ that the igneous dyke must be younger than 200 million years and older than 30 million years.
They would all have fitted nicely into the field relationships that he had observed and his interpretation of them.In other words, the age should lie between 197.2 million years and 203.6 million years.However, this error is not the real error on the date.He may suggest that some other very old material had contaminated the lava as it passed through the earth.Or he may suggest that the result was due to a characteristic of the lava—that the dyke had inherited an old ‘age’. 200.4 ± 3.2 million years) implies that the calculated date of 200.4 million years is accurate to plus or minus 3.2 million years.
