Mineral Id please

[Dmycha14]

Hi,

I'm fairly new to the gems and minerals and on a recent trip to the blackwood area in victoria I stumbled across a quartz rock and cushed it open to find a dark green, sort of waxy like inclusion inside with small pockets of a green/blue/grey powder like substance. Any ideas on what this could be?

Thanks, Dan.

Seems like there are so many different minerals it could potentially be! Might have to get this tested as it doesn't seem like something common enough to ID via a photo!

Thanks for the input though

 

[Dmycha14]

Absolutely puzzled!

Interesting specimen find, would be worth keeping and getting tested.

Just be careful it's not mercury,the old timers used a lot it in them days.blackwood forest had fine gold and deep

 

[Dmycha14]

Thanks! Any suggestions as to where I can get it tested in the western suburbs in Melbourne?

From the photo it looks like quartz with some chlorite. Quite common in the Victorian goldfields. Take it to the museum or the Vic geological survey.

Thanks Swright, Yes the museum sounds like the best idea! Looking forward to find out some info on the specimen to add it to the old knowledge bank. Cheers.

Looks like natural citrine with maybe olivine? Very dark in colour though so could be wrong.

Dan, I would also vote that odds are it is chlorite. Its valueless except for beauty. But don't stop collecting interesting specimens

As a rule of thumb i dont think quartz and Olivine will ever be found together. Chlorite sounds like a likely candidate.

I'm thinking Quartz and Citrine also. Plenty of that combination in Australia.

UV light, chlorite should fluoresce

Fair point shivan hence my doubt.
On reflection its next to impossible for the two to occur together except in highly active volcanic reigons, even then it would be an anomaly.
Far more likely then that this a pocket or bubble formed in the molten silica.
