Many times paleontologists will never know exactly how old a fossil is. Usually they guess its range or span of time. A good way of guessing the range is to look at the layers of rock that were formed by volcanoes. It's easier to guess the age of volcanic rock because it's brand new rock from the moment that it is spit onto the earth's surface.

This nuclear chemistry video tutorial explains how to solve carbon-14 dating problems. It discusses how to estimate the age of an expired piece of wood based on the radioactive decay of the C-14 isotope which undergoes beta decay. It discusses how to use two formulas given the carbon-14 decay rate in counts per minute per gram to estimate the age of the sample. This video contains plenty of examples and practice problems.

I'm thinking about getting back into dating. I'm only going to be seeing bits of cloth and broken plates, so there's no need to tell my wife. Besides - they're not what they used to be in terms of activity... Maybe I shouldn't put this on the internet. What, use restraint while posting to the web? Naah. It'll be fine. In other news, I hope this shows you how you can solve any radioactive dating problem from a very tiny amount of info. It's all related via some simple equations, so get familiar with them.

Relative and Absolute Dating Dr. Michael Wilson, Geology Department, Douglas College "Relative dating would be the placement of something in a sequence. So if we establish a sequence for an area we simply need to know what came first, then what came next, etc. For example, in a sequence of stratified deposits, laid down by a river or deposited by wind, we are talking about superposition as the basis for that sequence. Superposition means that the oldest deposits would be at the bottom and the youngest deposits would be on the top, in kind of layer cake fashion. So that principal has served us very well. If we have no means by which to absolutely date materials, we can still work out a sequence of events – that can be extremely important. So relative dating was really the only mechanism that people had available for dating archaeological and paleontological materials until the 20th century. There were a few absolute dating methods, and by absolute, I mean dating with respect to a measured time series. In other words, being able to place something in terms of a calendar– dating in terms of years. There were a few techniques that could be used in certain situations – counting of annual cycles in glacial lakes – we call these cycles “varves”. Counting those annual cycles of sediment deposition could actually allow us to determine the age of these lake deposits if they continued up to the present day. Or the use of tree ring dating – counting the rings in trees if we have logs preserved in a fairly recent site and could relate it to some known historic trees. Those were absolute dating techniques. But for the most part, until the 20th century, relative dating was the basis for archaeological, paleontological and geological dating."

THIS VIDEO IS LACED WITH SARCASM (to those who have difficulty sensing it). Scientists admit that radiometric dating, one of the fundamental techniques used to show the earth is billions of years old is flawed!!! The earth is not 4.55 billion years old. Watch and find out just how old it really is. Of course, scientists are always refining their techniques, it's part of of science works. Creationists have pointed to a number of "results" from radiometric dating that prove it doesn't work. Here I go over all the reasons why. Why is there Carbon-14 in some coal. Why did Potassium-Argon dating of the 1980 eruption of Mount Saint Helens give ages on the order of hundreds of thousands of years.

If you like this technical lecture from the 2017 IGH Conference, you can get it and over 70 more at: https://isgenesishistory.com/conference/ Listen to Dr. Andrew Snelling explain how radioisotope dating works, document the anomalies he has discovered with it, and examine how it can be used for relative dating purposes. Dr. Snelling completed a BS in applied geology at the University of New South Wales in Sydney, Australia, graduating with first-class honors in 1975. His PhD in geology was awarded in 1982 by The University of Sydney for his research thesis titled “A Geochemical Study of the Koongarra Uranium Deposit, Northern Territory, Australia.” Dr. Snelling worked for six years in the exploration and mining industries in Tasmania, New South Wales, Victoria, Western Australia, and the Northern Territory, variously as a field, mine, and research geologist. For over ten years, Dr. Snelling was a research consultant to the Australian Nuclear Science and Technology Organization for an international collaborative research project funded by the U.S. Department of Energy which involved university and government research scientists from the USA, UK, Australia, Japan, Korea, Sweden, Austria and Belgium. He is currently Director of Research for Answers in Genesis.
