1989 COMPILATION OF WORKING VALUES AND SAMPLE DESCRIPTION FOR 272 GEOSTANDARDS

Abstract

In this special issue, working values are reported for 272 international geostandards along with sample description. For many geostandards, the number of compiled data were not adequate enough for assigning working values. Users of geostandards are solicited to contribute more and more data particularly on trace elements. Think Geostan is a slogan that we wish to launch to set this problem in the limelight.
