Petrified wood - some with quartz

[Katie Waud]

Hello!

I've got about 120kg of petrified wood in my backyard, it was used as garden bedding which I'm told is common in chinchilla? ( I'm from Brisbane)

So really just trying to find out some more information on them, I chipped some off of one that seem to have quartz there? I'll add some photos, in this particular peice the "quartz?" Goes right thru from top to bottom.

Other bits have blue/clear tinge?

Thanks very much for any help and info

**also any idea what to do with it?

Hi Katie and welcome to PA.

I think the nearest people who could help you with your rock questions would be the North Brisbane Lapidary Club:
