| 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.
