2015-1-1 The concentration of germanium in the Earth’s crust ranges between 1.5 and 7 ppm (Scansetti, 1992). The total estimated world production of germanium was approximately 114,000 kg in 1982, but this did not include production in Zaire, which had one of the largest resources but for which no production data were available.

2021-4-2 Abstract The paper summarizes data on germanium and gallium concentrations in natural magmatic melts as follows from analyses of mineral-hosted inclusions and quench glasses in volcanic rocks. Germanium concentrations in melts vary from 0.96 to 17.6 ppm (1472 determinations). The geometric mean germanium concentration in silicate melts is 1.56 ppm, which is quite close to the
