The tablets were mainly made of the zinc carbonates hydrozincite and smithsonite, echoing the widespread use of zinc-based minerals in today's eye and skin medications.
Linear combination fitting of the XANES and XAFS region of the absorption spectra showed that the speciation of Zn for the hotspot at the edge of the pore and further into the soil matrix chosen in the intact samples was very similar and in forms resembling hydrozincite, Zn-sulfate, and willemite (Table 3, Fig.

Hydrozincite, probably as small encrustations, has been noted from San Carlos (Panczner, 1987).
The matrix pieces, from 5 to 18 cm across, show open cavities lined by crude pale green crystals of tarbuttite covered by carpets of white, acicular, glistening microcrystals of skorpionite, with white crusty areas of hydrozincite and sparse microcrystals of scholzite.
The natural color of this tarbuttite is a pretty, translucent apple-green, but in the Bahmanns' specimens the sheaves are uniformly coated by opaque, chalky white hydrozincite.
Zinc carbonates such as smithsonite and hydrozincite have not yet been identified, and aurichalcite has been found sporadically.

Bariand also displayed some outstanding minerals from Iran including red wulfenite crystals, hydrozincite, orpiment, caledonite and murdochite.
White, chalky masses and streaked or banded zones of hydrozincite occur with earthy red hematite, usually in the lower part of the oxidized orebodies and in fissures in the limestone.
Associated minerals are: hydrozincite and fraipontite.
