MPI-DING玻璃标样与大洋中脊火山玻璃主量元素的均一性研究
Major element homogeneity in MPI-DING and mid-ocean ridge glasses
摘要
Abstract
Reference materials are used in monitoring the accuracy,reproducibility and stability of the experimental data in in situ microanalysis. Homogeneity is important for reference materials. The MPI-DING glass was analyzed by an Electron Probe Micro Analyzer to discuss the homogeneity and stability of the synthetic glass. The results of major elements were compared with preferred value of other international laboratories and the deviation is basically within the range of 10％,meanwhile the RSD is mostly less than 5％. The results show that the data quality obtained from the electronic probe laboratory of Guilin University of Technology has reached the scientific research requirements. The electron probe was used to determine the major elements from the mid-oceanic ridges and volcanic glass of the eastern Pacific Ocean. The measurement results show that the homogeneity as SD is lower than 1. Compared with the data between the natural glass and the artificial glass,the content of elements in synthetic glass at different positions shows an even distribution. However,for the nature glass,elements in different locations are not absolutely homogeneous,and far below the standard homogeneity requirements. Different elements show different degree of homogeneity in different glass. Ca,K,Ti and Fe show more uniform distribution behavior in both acid and basic rocks.关键词
