A method i:. described for the preparation of trace element reference materials by a co-precipitated gel technique. The technique is applied to the manu- facture of multi-element calibration standards for the analysis of geological materials by direct-reading emission spectrome…
Economic gold deposits may be considered to fall into four classes on the basis of the concentration and precipitation mechanism: (a) primary one-stage hydrothermal extraction. with precipitation in vein conduits or on the sea-floor, (b) hydrothermal leaching of materials which have undergone a prior Au enrichment (multistage)…
