铜同位素天体化学研究进展
Research progress in copper isotope cosmochemistry
摘要
Abstract
Copper(Cu)is a moderately volatile,siderophile and strongly chalcophile element.The processes of celestial evolution such as nebula accretion,core-mantle differentiation,and impact melting can induce Cu iso-tope fractionation.It has extensive application prospect in the field of Cosmochemistry,such as tracing the evo-lution of primordial solar nebula and planets.This paper summarizes the current research status of Cu isotope in cosmochemistry:(1)cosmochemical properties of Cu;(2)Cu isotope analysis methods based on MC-ICP-MS,including chemical preparation and quality discrimination correction methods;(3)Cu isotope compositions of major celestial reservoirs(meteorites,Earth and Moon);(4)the processes that may lead to differences of Cu i-sotope composition between reservoirs,including high-temperature volatilization,nebula mixing,planetary dif-ferentiation and radionuclide decay processes;(5)the migration mechanisms of Cu during partial melting of mantle,magma differentiation,and oceanic crust subduction,including the limited explanations for Cu isotopic variations in these three processes;(6)practical application of Cu isotope cosmochemistry.关键词
