Nature, 1951
RECENTLY, Ramachandran and Wooster1 have obtained the elastic constants of galena, among other substances, from measurements on diffuse reflexion of X-rays, and reported disagreement with the values given earlier by one of us2. Ramachandran has also directed our attention to this in private communications.

Galena in pyrometasomatic deposits
Economic Geology, 1958"Galena is uncommon in pyrometasomatic deposits but does occur in Precambrian sulfide deposits of this type in central Sweden, in what were almost pure carbonate rocks. Associated minerals are in one deposit andradite and fluorite, but mostly magnesium-fluosilicates with tremolite or actinolite.

To complement the data, on the aqueous oxidation of sulphide minerals, that is, treatment of sulphides in aqueous solution at elevated temperatures under oxygen pressure, a study was undertaken of the aqueous oxidation of galena in sodium hydroxide solution.
