Galena and Unknown? Help Please =)

Hi there everyone,
I found this mineral near the Odin Mine again, Castleton, Derbyshire, UK, last weekend. I am just wondering what the pink mineral is in the first 2 photos, it weighs in at 160g, and contains a Galena/Sphalerite. Also, does anyone know what the shining/glistening mineral is the third photo. This sample is very heavy, about 370g and also contains a Galena/Sphalerite mix.
All ideas/messages appreciated,
Thanks, Matt.

1 and 2 may show barite ( or baryte?), as you say it is heavy. In that case, it should not fizz when put in acid.
3 may be quartz: in that case, it is harder than a knife and scratches glass.

I agree with Erik, photo 1 and 2 looks baryte.
Relating photo 3, I also would consider the possibility that there is more than one spice, as calcite / fluorite. Please see: [www.mindat.org]

Thanks for that guys, is there any test you can do to prove if it is calcite or fluorite.
Thanks, Matt

Quartz will scratch glass, calcite and fluorite won't.

Calcite will fizz when put into reasonably concentrated acids (eg. hydrochloric acid from hardware store) and will bubble slowly even in vinegar. Fluorite shouldn't react with either acid. Obviously, try the acid test with a small chip so you don't ruin your specimen.

The shiny mineral on the reverse side is Fluorite in tiny crystals, and the pink is most likely Barite, but pink calcite can also be found at the Odin mine, so you will need to test it, (calcite fizzes if a drop of diluted HCL is put onto it, and barite gives a good green coloured flame test.

Hi Matt,

photo 1 and 2: Baryte (quite heavy, scratched by a knife) or Calcite (gas bubbles with vine gear).
The 3. photo Quartz (harder than steel), Fluorite (crystalls are cubes, magnifying lens) or Calcite.

Greetings, Georg

Thanks for all your help guys. I will try out those tests.
Thanks, Matt
