Can radioactive dating used metamorphic rocks
Alternatively, if several different minerals can be dated from the same sample and are assumed to be formed by the same event and were in equilibrium with the reservoir when they formed, they should form an isochron. In uranium–lead dating, the concordia diagram is used which also decreases the problem of nuclide loss.

Isotopic systems that have been exploited for radiometric dating have half-lives ranging from only about 10 years (e.g., tritium) to over 100 billion years (e.g., samarium-147).
For most radioactive nuclides, the half-life depends solely on nuclear properties and is essentially a constant.
Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.
All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.
Dating the particles which make up the rock wouldn’t give you the age of the rock itself.
In addition, the redeposition process upsets the conditions necessary to achieve accurate results through radiometric dating.
This technique is generally used to date igneous and metamorphic rock, which are rocks that were once melted due to extreme heat and pressure.
Radiometric dating determines how long ago the liquid rock solidified into solid rock.
This transformation may be accomplished in a number of different ways, including alpha decay (emission of alpha particles) and beta decay (electron emission, positron emission, or electron capture).
Another possibility is spontaneous fission into two or more nuclides.
It is therefore essential to have as much information as possible about the material being dated and to check for possible signs of alteration.Tags: Adult Dating, affair dating, sex dating
