Geological Survey Professional Papers, No. E (). The above quotation tells us this: Only those radioactive dates are to be retained, which agree with the 19th century geologic column dating theories.

It is thought that the date of the impact can be dated by using various radiometric dating methods to date the tektites.

The argument that various radiometric dating methods agree with each other isn't necessarily true. Here we have the K-Ar and fission track dating methods agreeing with each other, but disagreeing dramatically with the radiocarbon and historical dating methods.
