Thalliomelane
A valid IMA mineral species
This page is currently not sponsored. Click here to sponsor this page.
Formula:
Tl(Mn4+7.5Cu2+0.5)O16
Specific Gravity:
5.285 (Calculated)
Crystal System:
Tetragonal
Member of:
Name:
for its relation (Tl analogy) to other supergroup members, cryptomelane and strontiomelane
First Tl-dominant member of the group. Approximately a more Mn(IV)-rich TlCu analogue of cryptomelane and strontiomelane. First Tl- and Mn-dominant oxide mineral to date.
See also Thallian Cryptomelane.
Probably resulted from Tl-for-K replacement, in the course of "weathering of a sulfide mineral assemblage under semi-arid to arid climate". Tl and others were likely released due to action of "Cl-, Br-, and I-bearing brines and pore waters".
Other associated minerals are Cu sulfates, Pb arsenates, and Bi oxy-chlorides.
