Several names and notices in the Shel phreng deal with iron oxides, often identified with Limonite : lcags rdo in the meltable medicinal stone section, gru bzhi, btsag, yug and rdo mkhris within the non-meltable medicinal stones, and sin dhu ra in the medicinal earth section. The important iron ore Hematite (smug po sbal rgyab) is found with the non-meltable medicinal stones.
The Shel phreng describes 4 minerals in a single notice :
smug po sbal rgyab (identified with the iron oxides Hematite),
dkar po sbal rgyab (identified either with Wollastonite or Limestone / Stalactites),
dkar po chig thub (identified with either Gypsum / Anhydrite or Wollastonite) and
smug po chig thub (identified with Goethite).
Hematite (Fe₂O₃), "bloodlike", in allusion to the vivid red colour of the powder, is an iron oxide mineral, and variable in its appearance - it can be in reddish brown, ocherous masses, dark silvery-grey scaled masses, silvery-grey to black crystals, and dark-grey masses. Large ore bodies of Hematite are usually of sedimentary origin, it is also the cause of red soils all over the planet (mindat.org).
Wollastonite (Calcium metasilicate), is a white mineral, common in metamorphosed impure limestone due to a reaction between silicates and carbonates (mindat.org)
Stalactites (ba nu) and Limestone (cong zhi or rdo thal) are basically Calcium carbonates.
Gypsum is the most common sulphate mineral, found as massive material, including the Alabaster variety, as well as clear crystals, the Selenite variety. When the mineral contains water, it is called Gypsum, when it does not, it is called Anhydrite (Calcium sulfate [CaSO₄]) (mindat.org).
Goethite is the most common simple iron oxide mineral, yellow-brown or red-brown to black with dull, silky or metallic lustre. A weathering product of numerous iron-bearing minerals. It may also form due to mineralization of lichen (Parmelia conspersa) thalli on metamorphics (e.g., gneisses), granites, feldspars (mindat.org)
There is an intriguing difference in the identification for dkar po chig thub (and, more important, also for the succeeding notice of gangs thig) between Yeshi (2018) and dGa' ba'i rDo rje (2018). Yeshi has Gypsum/Anhydride for the first, and the Zinc ore Smithsonite for the second. dGa' ba'i rDo rje repeats Wollastonite for dkar po chig thub (as for dkar po sbal rgyab) and gives Gypsum/Anhydride for gangs thig.
