Quick question about quartz?

Post by pilbarachad on Sat 08 Dec 2012, 10:41 am

This is one for all the amateur geos out there. Now since taking up detecting ive noticed the myriad of colours that quartz can come in, now im sure everyone has seen the common bleached white looking stuff and the tranlucent looking stuff.

My question is in relation to what minerals are associated with the different colours? Now i quite comonly come across the reddish/brown stained stuff that i assume has iron within it, Smoky grey stuff is pretty common up here aswell, not sure what the grey is associated with? Occaisionally ill find small patches of black quartz, blue/green and yesterday come across purple for the first time (whch happened to be right alongside some exploratory drillings????). Im thinking greens maybe associated with copper maybe??
Anyone one got a quick guide on whatcolours are caused by what minerals???

I collect rocks especially if they scream at me. Probably only hot rocks but it keeps me interested. Here's some pics of quartz varieties taken from the eastern goldfields and known gold bearing ground.
The big piece has a lot of iron in it and the other is stained grey. 2 totally different types but they came from areas where a lot of gold was found.

Now this pic is taken from the Calteck link and it's called Chrysoprase. Years ago I came across a seam of this stuff. It was on a back road and a grader had ripped the top off and pieces were everywhere. I had no idea what is was but a gem shop in Hannan St Kal told me it was Opalite. It was a big let down as I thought I had found some Ozzie jade, that was back in the days of the fever Razz

Thanks for the replys guys.

That link you posted Pete doesnt seem to work for me, ill look into it a bit further and see what i can figure out.

Bignuggs- its funny you included that stone that you thought was jade, as i grabbed a few bits of what i was told is pilbara jade or serpentine (i think) the other day aswell.
