Molybdomenite from
El Dragón mine, Porco Municipality, Antonio Quijarro Province, Potosí, Bolivia


Locality type:Mine
Classification
Species:Molybdomenite
Formula:PbSeO3
Comments:PXRD-analysed by G. Schnorrer (see https://www.mindat.org/mesg-805693.html; Schnorrer-Köhler, Günther, Grundmann, Günter, Lehrberger, Gerhard (1990) The El Dragón Mine, Potosí, Bolivia. The Mineralogical Record, 21 (2) 133-146).

Some molybdomenite from El Dragon was found to be paramolybdomenite (Pekov et al., 2025).

Paramolybdomenite from El Dragon is described as "thin-bladed crystals. Associated minerals are Co-bearing krut’aite–penroseite, chalcomenite, and dolomite. Molybdomenite- P21/c is pale yellow in transmitted light and has a greasy luster. It is brittle and has a Mohs hardness of 3. " (P21/c polytype is now known as paramolybdemenite); in Zhang, Jingnan; Yang, Hexiong; Gibbs, Ronald B. (2024) Molybdomenite-P21/c, Polymorphous with Molybdomenite and the Natural Analogue of Synthetic α-PbSe4+O3, from the El Dragón Mine, Potosí, Bolivia. The Canadian Journal of Mineralogy and Petrology, 62 (4). 643-652"
