A field method for making a quantitative estimate of altered tuff in sandstone
R. A. Cadigan
1954, Trace Elements Investigations 174
The use of benzidine to identify altered tuff in sandstone is practical for field or field laboratory studies associated with stratigraphic correlations, mineral deposit investigations, or paleogeographic interpretations. The method is based on the ability of saturated benzidine (C12H12N2) solution to produce a blue stain on montmorillonite-bearing tuff grains. The...
