Block with serpentine group mineral, as found in the underground works
Many around 0.5-1.0 mm purple fluorite. Because fluorite hardness is 4 only. Cannot get perfect and large crystal in Ma On Shan.
Purple fluorite. Nice cubic shape. The bigger crystal around 4 x 3 mm. Can see cleavage, if no cleavage this is perfect piece.
Vein of serpentine with talc, as found in situ in the underground works
Post mining growth of gypsum in the underground works walls
Many small rock crystal, some position has cubic shape which is fluorite. Before I had been Ma On Shan Iron Mine no quartz. I was wrong.
A tiny but nicely crystallized fluorite from a historical mine in Hong Kong. Old specimen.
Ma On Shan Iron Mine an image at October 2019, this is a big different compare with old photo. Now it is looks like a forest and government build up a wall to avoid people go inside the mine. The 110M.L. is meaning meters above sea level. Old rails are under the water.
240M.L. is great different with old photo. Now no words and build up a wall.
Old stones were mined in Ma On Shan Iron Mine. They are showing in the chapel for visitors watch.
