Cerussite:
Crystal system- Orthorhombic. It belongs specifically to the aragonite group and frequently displays iconic v-shaped,chevron or reticulated snowflake twinning.
Rock formation: It forms as a secondary mineral in the oxidation zones of lead ore deposits. This occurs when carbonated groundwater chemically interacts with primary lead sulfides like galena.
Mineral class: carbonate
Hardness: 3-3.5 on the MOHs scale
Sphalerite:
Mineral class- Sulfide
Crystal system- Cubic
Hardness- 3.5-4 on the MOHs scale
Rock formation-
Hydrothermal veins: Precipitates from hot,metal rich aqueous fluids moving through fractures in crustal rocks.
Carbonate replacements: Replaces original minerals inside limestone and dolostone via infiltrating hydrothermal solutions.
SEDEX deposits- Forms layered sedimentary exhaustive deposits when hot fluids discharge onto ancient sea floor.
Baryte:
Crystal system-
Orthorhombic (commonly tabular or bladed crystals)
Rock formation-
Hydrothermal veins and sedimentary rock environments (like limestone and dolostone)
Mineral class-
Sulfate
Hardness-
3-3.5 on the MOHs scale
