Strategy
« on: June 20, 2013, 08:27:48 PM »
I read that some people locate serpentine and then they look for jade type material.
What's the plan - How do you go about finding new stone or spots?
I like the bigger stuff to make spheres from (never made one yet and probably years away from doing it).  What's the game plan - how does one go about finding "new stone" or a new "spot"?
I'm open for anything - as long as it polishes well and is large enough
Can anyone lay-out strategies on how to locate spots of different rocks that fits the bill?
Thanks - interested in what comes out of this post

High Big stuff, I just look at the geological structures in my area and also old mining maps I have obtained from Geoscience Australia.  There is a lot of rhyolite in my area, it is a very hard material and has a brilliant polish, we have massive deposits.  From looking at the geo structures, I have found thunder eggs which went suppose to be in this area.  Mate as far as I go, I just have a look at areas people haven't mentioned and then have a look around,it surprising what you will find.  Even the pink and grey granites make great spheres.  Good Luck  ;)

Big stuff a wide range of minerals and quite few rocks make good looking sheers including the granites. One of great thinks about sprees is the wider range of material that is often used. If you are new to fossicking I would recommend starting with known areas, rhyolite and Jasper's are a good start. I would also read on as much geology as you can, while some rocks are widespread such as granite, most form in very specific environments. Nephrite jade is an alteration product of other minerals, the other minerals must exist first or be added to provide the right chemical mix, it then needs the right temperature and pressure to produce nephrite otherwise other minerals result. After that is needs to be exposed on the surface so we can find it. In the Tamworth area the nephrite occurs with a meter or so of the Peel fault, be 2 Meters off either side and no nephrite.

I look at rock's wherever i go whether it be driveway's, roadside stops, or anywhere else. Anything I can't ID on the spot or that is interesting comes home for further perusal and identification.
Every mineral or gemstone is found in association with others, once I've ID'd what I have I research each type of rock, mineral or gem. I then go back looking for anything interesting that may possibly be found in association with what I've found. If I then start finding those I keep looking....If I find something unexpected the whole process starts again

I may not like shovels, but there is a lot of work in the way I fossick ;)

Cheers

    We purposely backroad as much as possible going to and from established fossicking locations [some known, some ours], checking every road cut and watercourse we come across. Wet flows are obviously best at low water, but even dry washes consentrate pieces of whatever is in the area. Another place to look is ant hills, as they pull bits of underground mtl. up in the construction of their nests, magnifier helpful here.
