Cofty regarding your reading assignment to me I got to page 2
Page 2 of radiometric dating pp2&3
Also unlike the hourglass, there is no way to change the rate at which radioactive atoms decay in rocks . If you shake the hourglass, twirl it, or put it in a rapidly accelerating vehicle, the time it takes the sand to fall will change . But the radioactive atoms used in dating techniques have been subjected to heat, cold, pressure, vacuum, acceleration, and strong chemical reactions to the extent that would be experienced by rocks or magma in the mantle, crust, or surface of the Earth or other planets without any significant change in their decay rate. In only a couple of special cases have any decay rates been observed to vary, and none of these special cases apply to the dating of rocks as discussed here . These exceptions are discussed later.
My response:
There saying here that it is very accurate, despite extreme conditions.
But when Mt St Helens errupted in 1980 they used radiometric dating on the rocks dating them up to 2.8 million years old.
Mt. Etna erupted 2100 years ago but the rocks came back dated 25 million years old.
Sunset crater, Northern Arizon erupted in 1065Ad the rocks came back dated 200,000 years old
Lava flows at Mt. Ngaurhoe, New Zealand erupted in 1949, 1954 but the rocks came back dated 274,000
years old.
Mt. Etna basalt, Sicily erupted in 1971 the rocks were dated 140,000 to 350,000 years old.
All of the samples from volcanic eruptions of known times and dates were carefully collected and sent to labs.
They always come back dated hundreds of thousands of years to million years old.
They never come back with a note "too young to measure."
When man know the dates of rocks, the dating techniques dont work.
But we are supposed to trust them when we dont know the dates.
Thats Psuedo science.
