About Weibullite
Formula:
Pb5Bi8Se7S11
Colour:
Steel-gray
Lustre:
Metallic
Hardness:
2 - 3
Specific Gravity:
6.97 - 7.145
Crystal System:
Orthorhombic
Name:
Named after Kristian Oskar Mathias ("Mats") Weibull (23 December 1856, Starbo, Dalarna, Sweden - 26 May 1923, Stocksund, Sweden), geologist who first described the mineral.
Weibull wrote a number of dissertations and essays in brochure form and in journals, partly in mineralogy, petrography, and chemical crystallography. Among Weibull's many works in mineralogy and crystallography are studies of manganese minerals from Dalarna, minerals from VÀstanÄ in SkÄne, on the composition and crystal form of arsenic, and crystallographic studies of platinum compounds and of a number of benzene and toluene derivatives.
