Who developed radiometric dating

Such failures may be due to laboratory errors (mistakes happen), unrecognized geologic factors (nature sometimes fools us), or misapplication of the techniques (no one is perfect).In order to accomplish their goal of discrediting radiometric dating, however, creationists are faced with the daunting task of showing that a preponderance of radiometric ages are wrong — that the methods are untrustworthy most of the time.

The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons.

Not only that, they have to show the flaws in those dating studies that provide independent corroborative evidence that radiometric methods work.

This is a tall order and the creationists have made no progress so far.

The Pierre Shale also contains volcanic ash that was erupted from volcanoes and then fell into the sea, where it was preserved as thin beds.

These ash beds, called bentonites, contain sanidine feldspar and biotite that has been dated using the 40Ar/39Ar technique.
