We recently bought a mixed box of rocks which contained two rocks we can’t identify, does anyone know what they are please?
In the consignment we also received a huge lump of Labradorite and Blue Aventurine, must be over 8lb each but I haven’t measured and weighted them yet.
Here are the two unidentified specimens:

If anyone can help in identifying these we would be very grateful
Thanks

Hi John,
that would be very kind of you thank you, I have your email address so I will email you directly later today thank you
If you haven’t solved it already –
The first of your unknowns looks like part of an ore vein: at a very tentative guess tin or tungsten (+ quartz, fluorite, ?barite)The second looks like a dolomitic marble. The yellow-green mineral may be tremolite – though obviously a photo is not enough for identification. If you’d care to send me a representative chip of each rock, I’ll be happy to try and reach more definite conclusions; I’m a geologist, and I have a Raman spectrometer.
