Radioisotopes in dating fossils, the global tectonic rock cycle
Doesn’t Carbon Dating Disprove the Bible? | Answers in Genesis
It can be concluded that a discussion of "transitional forms" is moot and useless. In the case of samarium—neodymium dating, however, the chemical similarity of parent and daughter adds another complication because fractionation during crystallization is extremely limited.
Argon dating involves a different technology from all the other methods so far described, because argon exists as a gas at room temperature.
This principle would seem self-evident, but its first enunciation more than years ago by Nicolaus Steno represented an enormous advance in understanding. Given the estimated concentrations of Uranium and Thorium in the earth's surface, current decay rates and the estimated helium content of the atmosphere, the implication would be that this could not have been going on for N,, years.
“History of the Earth”
Given the estimated rate of influx of each substance, and given the current concentration of these dissolved minerals in the sea, and working backwards, we get values ranging from N00 to N00, years. In time, the global environment and atmosphere stabilized, and a good portion the ice extending down from the polar regions receded.
These findings point to the age of the earth being much younger than evolutionary scientists would suggest. However, the creationist acknowledges that the ordering would be approximate, based on the chaotic nature of the flood, and that different strata models would be found in different parts of the world, based upon the local ecosystem and what animals dwelt in it.
Where this occurs at the edge of a continent, as along the west coast of North and South America, large mountain chains develop with abundant volcanoes and their subvolcanic equivalents.
Is the explanation of the data derived from empirical, observational science, or an interpretation of past events historical science? Here is the "survival of the fittest" tautology: To do this, scientists use the main isotope of carbon, called carbon 12C.
The sequence of a layered sedimentary series is easily defined because deposition always proceeds from the bottom to the top. These methods will be discussed in the following chapter.
The exploitation of the samarium—neodymium pair for dating only became possible when several technical difficulties were overcome. How can scientists accurately adjust their calculations if the isotope ratios were never observed and recorded?
No theory exists to show that all phenomena are natural phenomena. Variations such as this demonstrate the concept of what is often referred to as "micro-evolution.
But to top it off, the popular scenario involves things happening in a primordial sea, implying an excess of water. Are there any assumptions involved in the dating method?
