1982 Compilation of Elemental Concentrations in Eleven United States Geological Survey Rock Standards
Tóm tắt
Elemental composition data on eight older (AGV‐1, BCR‐1, DTS‐1, G‐1, G‐2, GSP‐1, PCC‐1 and W‐1) and three newer (BIR‐1, DNC‐1 and W‐2) USGS rock standards have been collected from institutional reports and journal articles from 1972–1981. This collection was combined with data from previous compilations and “consensus values” for up to 79 elements determined by comparing overall means, medians, and individual means based on analytical techniques.
