Distribution typically complete for ICP; may be truncated (censored) for NA.
In association with Zn, Cd, Pb, anomalous Ba may indicate Sedex or VHMS mineralization (the latter more particularly in Phanerozoic rocks). This seems to hold true even when Aqua Regia digestion (which is ineffective in breaking down barite or feldspar) is applied.2. As an Aid to Geological Mapping
Elevated values may indicate presence of felsic rocks, especially kaolinized intrusives (in association with K), or calcareous rocks (in association with Ca, Mg, Sr).
