Documentation and evaluation of Mossbauer data for minerals

More than 2,500 Mossbauer spectroscopic studies on minerals have been publi shed since 1960. These papers contain approximately 8,000 sets of Mossbauer mineral data on at least 400 different minerals. This information has been compiled into a database that includes isomer shifts, quadrupole splitting s, and magnetic hyperfine interactions at room, liquid nitrogen, and liquid helium temperatures. The database provides a profile of the Mossbauer rese arch performed to date on minerals, including type and locality of minerals investigated, significance of the studies and results, and location of the research facilities. The data and information are available both in printe d and magnetic form. With the establishment of this resource, the Mossbauer Effect Data Center h as begun a systematic evaluation of the Mossbauer mineral data. It is antic ipated that this resource can be used for the identification of minerals as powder X-ray diffraction data is.
