During the 19th century, and even well into the twentieth, geological chronology was very crude.

Also, it is of little use in anything more recent than 5,000 years ago.The radioactive isotope Carbon 14 has a half-life of 5,730 years.Ihis has made it useful for measuring prehistory and events occurrring within the past 35 to 50 thousand years.Carbon 14's half-life is not nearly long enough to measure dates in the geological past.For that elements with a half life of many millions of years are required.
