Most geologists accept radiometric dating techniques as valid because Free ps3 sexy chat

The geologist may have found some fossils in Sedimentary Rocks A and discovered that they are similar to fossils found in some other rocks in the region.

He assumes therefore that Sedimentary Rocks A are the same age as the other rocks in the region, which have already been dated by other geologists.

He may suggest that some other very old material had contaminated the lava as it passed through the earth.

Or he may suggest that the result was due to a characteristic of the lava—that the dyke had inherited an old ‘age’. 200.4 ± 3.2 million years) implies that the calculated date of 200.4 million years is accurate to plus or minus 3.2 million years.

’ In fact, there is a whole range of standard explanations that geologists use to ‘interpret’ radiometric dating results.

Someone may ask, ‘Why do geologists still use radiometric dating?

The field relationships are generally broad, and a wide range of ‘dates’ can be interpreted as the time when the lava solidified.

What would our geologist have thought if the date from the lab had been greater than 200 million years, say 350.5 ± 4.3 million years?

He would say that the date represents the time when the volcanic lava solidified.

Such an interpretation fits nicely into the range of what he already believes the age to be.

In the same way, by identifying fossils, he may have related Sedimentary Rocks B with some other rocks.

Creationists would generally agree with the above methods and use them in their geological work.

In fact, he would have been equally happy with any date a bit less than 200 million years or a bit more than 30 million years.
