- The Identity of Chalcostibite (Wolfsbergite) and Guejarite. ([Samuel] S. L. Penfield and A. Frenzel, Amer. Journ. Sci., IV, 27-35, July 1897, 4 figs.; and Zeits. Kryst. Min. XXVIII, 598, 1897).—The identity of chalcostibite and guejarite, first suggested before this Society,1 has now, from a reexamination of the original material, been conclusively proved.
The mineral was first described, from Wolfsberg in the Harz, by Zincken in 1835, under the name Kupferantimonglanz; it was determined by G. Rose to be orthorhombic, but terminal faces were wanting on the prismatic crystals; and an analysis by H. Rose gave to it the formula Cu2S.Sb2S3. The name chalcostibite was proposed by Glocker in 1847, and wolfsbergite was given by Nicol two years later; although the latter is perhaps the more familiar name, the present authors adopt, with Dana, the older name chalcostibite. It was not until much later (1891) that a more complete crystallographic description of the mineral was given by Laspeyres.
"Guejarite" was described in 1879 by E. Cumenge³ from Güejar-Sierra, on the northern slopes of the Sierra Nevada, Spain. The results of his analysis, which were only given to half per cents., led to the formula Cu2S.2Sb2S3. C. Friedel noticed at the time that the crystallographic measurements of the prism zone were in agreement with the only zone then known for chalcostibite, but it was only the later measurements of Laspeyres that showed the complete crystallographic identity of chalcostibite and guejarite. Here it may be mentioned that Breithaupt in 1857 described chalcostibite from the "guejarite" locality,³ giving an analysis and an angular measurement. This was apparently overlooked by Cumenge, nor is it mentioned by the present authors. — (The Mineralogical Magazine and Journal of the Mineralogical Society, volume XI, Simpkin, Marshall, Hamilton, Kent & Co., Limited, Londres, 1897, page 338)
