摘要:
Ten U.S. Geological Survey rock standards have been analyzed for trace elements by instrumental neutron activation using a low flux reactor and Ge detectors. Results compare favorably with the current working values for all elements except Mo. REE values that have been determined are generally slightly lower than accepted values. Data obtained for rocks that have very low trace element concentrations (e.g., BIR‐1) will aid in refining the working values for these standard
