Yes, layers can be seen in ice cores extracted from deep in glaciers in Antarctica and Greenland, but less than 2,000 annual layers can be counted visually for a very simple reason.) is the time required for a quantity to reduce to half its initial value.The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo, or how long stable atoms survive, radioactive decay.The term is also used more generally to characterize any type of exponential or non-exponential decay.For example, the medical sciences refer to the biological half-life of drugs and other chemicals in the human body. The original term, half-life period, dating to Ernest Rutherford's discovery of the principle in 1907, was shortened to half-life in the early 1950s.Rutherford applied the principle of a radioactive element's half-life to studies of age determination of rocks by measuring the decay period of radium to lead-206.

Reverend Benjamin Richardson and Reverend Joseph Townsend were a couple of early geologists involved in this work. Obviously, even Lyell was not pushing evolution at the time.By 1830 Lyell's famous textbook, Principles of Geology, came out. Such was the age of the great creationist geologists!
