Formula:
Tl, As, O, H(?)
"Micaceous subparallel crystals of poorly crystalline to amorphous thallium arsenates (representing previously unknown mineral species), forming porous aggregates up to 100 µm. These Tl arsenates are intergrown with dolomite and Ca-Fe-arsenates and appear as two chemically different phases." (Ðorđević et al., 2020).
"The first, more common phase shows a variable Tl:As ratio ranging from ca. 2.1 to 4.1 and a variable Ca content (2.2 to 4.1 at.%)" (Ðorđević et al., 2020).
The phase is also characterised by Raman spectroscopy.
