Most absolute age determinations in geology rely on radiometric methods. The earth is billions of years old. The main condition for the method is that the production rate of isotopes stays the same through ages, i. The production of isotopes from chemical elements is known as decay rate and it is considered a constant. Because it is driven by sun activity it was always questioned.

Radiometric Dating

Community Guidelines. An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.

Radiometric clocks are naturally occurring radioisotopes, such as 14C, with known half-lives, that are used to date organic materials.

Radiometric dating is a technique used to date a material and to find the relative age of the material. When a rock is radiometrically dated then the age of rock is determined when the rock crystallized. The crystals of the rocks will roughly be of the same age. The radiometrically dated metamorphic rock determines the age, when the rock was heated during metamorphism. Igneous rocks and high-grade metamorphic rocks are the most likely to be entirely formed of minerals that crystallized when the rocks formed. As most fossils are found in clastic sedimentary rocks, which are made of weathered and eroded minerals and bits of rock of various ages, it is unlikely to be able to make an radiometric age determination of a rock in which a fossil is found. Metamorphism the of age the indicates usually rocks metamorphic in minerals of dating Radiometric element different a of isotope the to decay radioactive by change and unstable are that masses) atomic different have that element the of (forms isotopes have elements of number A series decay Radioactive.

At time zero in the diagram, which could represent the crystallization of minerals in a rock, there are 32 red dots. After one half-life has passed, there are 16 red dots and 16 green dots. After two half-lives have passed, there are 8 red dots and 24 green dots. The following graph illustrates radioactive decay of a fixed amount of an isotope.

the radiometric date of a metamorphic rock most likely represents when the rock was heated during metamorphism. to date a sedimentary rock layer between two igneous rock units, geologists use radiometric dating and assume that the sedimentary layer's age .

You can see how the proportions of the isotopes from the cartoon above are graphed as percentages at half-lives 0, 1, and 2 below. The following table lists a selection of isotope pairs that are used in making radiometric age determination.

Note that carbon has a relatively short half-life, which makes it useful only for young, carbon-rich geologic materials, less than about 70, years old. Igneous rocks and high-grade metamorphic rocks are the most likely to be entirely formed of minerals that crystallized when the rocks formed. As most fossils are found in clastic sedimentary rocks, which are made of weathered and eroded minerals and bits of rock of various ages, it is unlikely to be able to make an radiometric age determination of a rock in which a fossil is found.

The ages, in years, are based on radiometric dating. Many rocks contain radioactive elements which begin to decay at a very slow but measurable rate as soon as the parent rock is formed. The most common radioactive elements are uranium, rubidium, and potassium, and their decay ("daughter") products are lead, strontium, and argon, respectively. The radiometric date of a metamorphic rock most likely represents when the a closed system during the entire period since its formation this is why radiometric dating can't be used with. What does the radiometric date of metamorphic rock most likely represent? Top Answer. Wiki User. system during the entire period since its formation this is why radiometric dating can't be.

The age of a rock containing fossils can usually be narrowed down by measuring the ages of metamorphic or igneous rocks in stratigraphic relation to it, such as a lava flow on top of a layer of sedimentary rock. Skip to main content. Geologic Time.
