Table 2 – 1.—Density of Minerals
(H. Berman)
The densities of minerals here listed are selected from the complete list by Rosenholtz and Smith, Rensselaer Polytechnic Institute Eng. and Sci. Series, No. 34, Troy, 1931, who have compiled all the published values. The ranges given are, in most cases, not significant, since they arise from an uncritical compilation of the limiting values found in the literature. Some minerals have a considerable spread in specific gravity as a result of isomorphous substitution, and in these instances it is necessary to correlate a specific chemical analysis with the given value of density. In a number of instances, new values marked * have been substituted for those in Rosenholtz and Smith.
