Detailed Mineral List:

ⓘ Albite
Formula: Na(AlSi3O8)
Colour: white to pink
Description: As rock forming matrix and as microscopic crystal overgrowths lining fractures.

Habit: capillary
Colour: white
Description: Scattered capillary crystals in fracture voids.
ⓘ Annite
Formula: KFe2+3(AlSi3O10)(OH)2
ⓘ Calcite
Formula: CaCO3
Habit: massive
