Uranium series dating of quaternary deposits

Unfortunately, glacial sediments are typically difficult to date.

It is effective on timescales of several millions of years.It assumes that boulders have not been buried and then re-exposed at the Earth’s surface.Geologic studies of active tectonism are greatly aided by definition and time calibration of local stratigraphic sequences.Because all dating techniques may be subject to considerable error, reliability should be assessed by stratigraphic consistency between results of different dating methods or of the same method.Relative-dating techniques are nearly always applicable but are not precise and require calibration.

Correlation techniques are locally useful and depend on recognition of an event whose age is known, such as a volcanic eruption or a paleomagnetic reversal.

With a half-life of only 5730 years, carbon-14 dating has nothing to do with dating the geological ages! Hovind is confusing the carbon-14 "clock" with other radiometric "clocks." The only thing in the geologic record which has anything to do with calibrating carbon-14 dating is the coal from the Carboniferous Period.

Being ancient, the C-14 content has long since decayed away and that makes it useful in "zeroing" laboratory instruments. Hovind would take the trouble to do a little reading from something other than creationist publications he would not make such an outrageous statement.

Adequate age control is thus a limiting factor in studies of active tectonism.
