Can radiometric dating be used with metamorphic rocks

These scientists and many more after them discovered that atoms of uranium, radium and several other radioactive materials are unstable and disintegrate spontaneously and consistently forming atoms of different elements and emitting radiation, a form of energy in the process.The original atom is referred to as the parent and the following decay products are referred to as the daughter.Potassium is a component in many common minerals and can be used to determine the ages of igneous and metamorphic rocks.The Potassium-Argon dating method is the measurement of the accumulation of Argon in a mineral.It is best used with rocks that contain minerals that crystallised over a very short period, possibly at the same time the rock was formed.This method should also be applied only to minerals that remained in a closed system with no loss or gain of the parent or daughter isotope.Perseverance over three years of secret research to develop the radiocarbon method came into fruition and in 1960 Libby received the Nobel Prize for chemistry for turning his vision into an invaluable tool.The basic principle Carbon has three naturally occurring (n is a neutron and p is a proton) After formation the three carbon isotopes combine with oxygen to form carbon dioxide.

In contrast to a method such as Radiocarbon dating, which measures the disappearance of a substance, K-Ar dating measures the accumulation of Argon in a substance from the decomposition of potassium.

The discovery of by the French physicist, Henri Becquerel, in 1896 paved the way of measuring absolute time.

Shortly after Becquerel's find, Marie Curie, a French chemist, isolated another highly radioactive element, .

Radioactive elements decay at a certain constant rate and this is the basis of radiometric dating.

But, the decay elements need to be set, much like you would re-set a stop watch for a runner, to ensure an accurate measurement.

The carbon dioxide mixes throughout the atmosphere, dissolves in the oceans, and via C in the original sample will have decayed and after another 5568 years, half of that remaining material will have decayed, and so on.
