How is potassium 40 formed

WebThe Potassium (K) decay (DK) collaboration has built, tested, and characterized a novel detector to accurately measure the decay rates of Potassium-40 ( 40 K) for the electron capture decay channel to ground state Argon-40 ( 40 Ar). 40 K is an unstable isotope of potassium with a very long half-life of approximately 1.4 billion years. WebThe type of rock formed is controlled by the parent rock and the pressure/temperature conditions. Metamorphism causes growth of new minerals, rotation or deformation of mineral grains, and recrystallization of minerals. the cycle is completed when the rocks melt again and become magma.
