Description
Comments:Hydrocerussite is associated with cerussite in the manganese pods; crystals of hydrocerussite coated with cerussite or calcite are not uncommon. Large crystal masses are often found just outside the manganese pod in the altered limestone wallrock, as pCO2 needs to be high for hydrocerussite to form.
Habit:pseudo-hexagonal xls and plates, often stacked into 'worms'
Colour:pearly white, pale green
UV Fluorescence:none
Quality of samples:Good crystals or rich for species - important (!)
Rarity at site:Rare
Confirmation
Validity:Confirmed
Confirmation Methods:XRD
SEM-EDS
