Nd isotopes

Neodymium (Nd) isotopes are different forms of the element neodymium, which has atoms with the same number of protons but varying numbers of neutrons. These variations can reveal information about geological processes like the age and origin of rocks, Earth's mantle composition, and crust-mantle interactions. Scientists analyze Nd isotopic ratios using specialized techniques to trace the history of Earth's materials, understand magma sources, and study the evolution of the Earth's crust. In essence, Nd isotopes serve as natural "tags" that help scientists decipher Earth's geological past and processes.
