About TlapalliteHide

viridian green RHS- I28A
Vitreous, Waxy
Specific Gravity:
4.65 - 5.38
Crystal System:
From Nahua "tlapalli", paint, referring to the occurrence of the mineral as paint-like films on fracture surfaces at the discovery locality.
Formerly reported formula: H6(Ca,Pb)2(Cu,Zn)3(TeO3)4(TeO6)(SO4).

The second mixed-valence tellurium oxysalt mineral to have its crystal structure determined, after carlfriesite. In addition, tlapallite contains a new phyllotellurate anion.

Classification of TlapalliteHide

Approval Year:

4 : OXIDES (Hydroxides, V[5,6] vanadates, arsenites, antimonites, bismuthites, sulfites, selenites, tellurites, iodates)
J : Arsenites, antimonites, bismuthites, sulfites, selenites, tellurites; iodates
L : Tellurites with additional anions, without H2O
