older dating in the us Paleomagnetic dating is based on the fact that

Scientists date these changes in polarity through another technique, such as potassium-argon radioactive dating.This has resulted in the calibration of the pattern of changes in the earth's polarity over many millions of years.This is a blog with tons of information about dating and we will share with the world the best dating stories and experiences that we get from our viewer!

As time passes, the organic components of bone (mostly fat) are lost primarily through bacterial action.

Since these components contain nitrogen, there is a progressive loss of that element.

However, the assumption of contemporaneity may not always be correct.

This is due to the fact that one or both of the objects may have been moved or redeposited into a different location.

At the same time, percolating ground water deposits trace amounts of fluorine and other elements, such as uranium, into the bone.

As a result, the amount of fluorine Fluorine analysis can be used only as a relative dating method because the rate of decay and the amount of dissolved minerals in the ground water varies from site to site.can be used to tell us whether or not the animals they were from actually lived at about the same time.This relative dating method is based on the fact that there are specific progressive chemical changes in skeletal remains that result from burial underground.However, relative methods are , which is that if there are layers of deposits, those laid down first will be on the bottom and those laid down last will be on the top. However, geological strata are not always found to be in a neat chronological order.Wind and water erode strata and some areas are uplifted or even tilted.In other words, they may no longer be in their primary context.
