In-situ Sr isotopic measurement of scheelite using fs-LA-MC-ICPMS

•Sr isotopic compositions of scheelite can be obtained by fs-LA-MC-ICP-MS.•Two scheelite samples have the potential to be reference materials for Sr isotopic determination by LA-MC-ICP-MS.•In-situ Sr isotope of scheelite is a powerful tool to decipher the degree of fluid-rock interaction in ore-forming processes.
