So, we have a “clock” which starts ticking the moment something dies.Obviously, this works only for things which were once living.C) dating usually want to know about the radiometric dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering—the reason Jesus came into the world (See Six Days? He said, This only makes sense with a time-line beginning with the creation week thousands of years ago.It makes no sense at all if man appeared at the end of billions of years.
For example, if the cultural contents of the lower deposit are Mauryan in character, appropriately this deposit may be assigned a date between 400-200 B. Similarly, if the cultural equipment of the upper deposit are of the Sunga period, this deposit has to placed between 200-73 B. Quite often, the archaeologist decided the change of stratum on the basis of the feed of the deposit.
Sr ratios and, on a gross scale, marked variations can be found between the strontium isotopic compositions of marine and continental waters.
Carbonates deposited from, and calcareous organisms living in these waters will have distinctive The presence of uranium-rich accessory minerals (e.g., zircon, monazite, sphene and apatite) in acid to intermediate igneous and metamorphic rocks enables the uranium-lead technique to be applied to the problems of precisely defining crystallization ages of such minerals.
Because of its lower relative abundance, its longer half-life and the universal presence of common Sr (the radiogenic isotope), the Rb-Sr method does not usually produce a very precise age when applied to young rocks (e.g., Mesozoic or Cenozoic).
However, it is superior to the K-Ar method for dating rocks that have suffered thermal or dynamic metamorphism and has been widely applied to rocks of Precambrian age.
