Shortcomings of radiocarbon dating

It's often assumed that one diatom bloom—a rapid growth period—occurs per year in a lake environment.However, diatoms make use of silica to construct their skeletons, and the amount of silica in lake environments can be increased by wind-blown dust and volcanic eruptions.First, it must really be the case that the varve count ages are generally equal to the radiocarbon ages.

Tim Clarey) and a geologist from Answers in Genesis (Dr.Upon coming in contact with cold ocean water, these salts would have precipitated out, forming large, exceptionally pure, salt deposits. But Davidson and Wolgemuth included a "twist" on their argument: They claimed that radiocarbon dating of leaf, branch, and insect fossils within the lake sediments showed very good agreement between the radiocarbon ages for these fossils and the ages one would expect based on a simple counting of the varve layers.This good agreement, Davidson and Wolgemuth claimed, proved that most of the layers did indeed represent annual events, thereby proving that the earth must be at least 50,000 years old.Usage by ICR does not imply endorsement of copyright holder.Archaeologists utilize several methods to analyze data from the past.
