Fossicking Locations / Round Australia Trip
« on: July 22, 2013, 09:24:42 PM »
Greetings Alfer's,

So I have been off this forum for quite some time, I have had a pretty major health issue which is now hopefully resolved and have been working flat out for a small exploration company. Now that our mining industry is winding down I have been layed off which brings me to beg the question, where to go from here?

I have always wanted to do a round the country trip to look for gems and fossils so I am reaching out and asking for tips on where to go, what I will need and how long I should plan to stay at certain times of the year. There is a good chance that this trip will probably take longer to plan than to go on and that life might yet get in the way resulting in the trip being done in stages or quite a few years down the track. It would be awesome if anyone could PM me their contact details so I could catch up and possibly get a private tour (the offer is always open on my end) or if anyone could PM me maps, details etc that would be great. I am not sure about buying a camper etc yet, more likely to get a roof top tent for my cruiser.

I would love to hear from anyone who has done a big fossicking trip and I would appreciate any ideas and suggestions,

Take care, stay well and stay happy,

A salt solution is a great idea and might work well, just make sure that you rinse several times to avoid any salt from encrusting or damaging the specimen in the long run. The Museum of victoria preserves its' fossilised dinosaur bones collected on the coast with a solution of glue dissolved in alcohol. you could experiment and create your own solution. I think that they use super glue and the solution is acrolack. I have preseved limestone fossils with diluted pva glue which I apply to a specimen in several coats. Samples I have treated in this way still look great now, ten to fifteen years later.

I have a 1998 Landrcruiser 4.2 litre diesel, it has a two inch lift, whinch, snorkel, front and back bull bar, cb radio, two 90 litre water tanks with bilge pump, long range fuel tanks, roof racks, shower and I also have a removable drawer system for camping trips and an awning with mosquito net. It is an awesome looking and performing rig and consumes just under 13 litres per 100k. Having said that it is very slow off the mark but has heaps of grunt when you need it. It is extremely comfortable and my wife drives it most of the time so I usually end up taking my work car which is a 1998, 70 series Toyota Troop carrier which is very capable but not as comfortable. I used to own a landrover defender which was awesome both on and off road, they are a bit like driving a truck but they consume only 11 litres per 100k which is incredible for such a big car. When all is said and done cars are a very personal thing, it sounds like all you need is something that will get you out of a jam which is anything that has 4 wheel drive capability. Subaru's can be awesome all wheel drives but they are usually quite thirsty for small cars as are pathfinders. You might consider a Hyundai Tuscon or equivalent, good ground clearance, cheap to buy and run. Good luck and thanks for letting me ramble about my cruiser, I love that car,



Nice work!!!

I wish I could help you out. I just got hold of some in crystaline form and have so many iron stained minerals that I would love to try it out on. Maybe you could try it out on the poorer samples until you have it mastered. I am a long way off trials,

I still want my prize for starting the longest thread. Guys there is no need to get nasty or go and kill some animals in an inhumane way to try and prove a point. I don't think anyone has changed their opinion on the topic and all I think now is that I would be too scared to express my disbelief in divining as those who believe in it are likely to get violent rather than try and analyse why it might "work" for them in a peaceful discussion,

Glad that you and your family are alright, I am in Bairnsdale and I felt it and heard it to as my room creaked and groaned. Hopefully the mines I am going in tomorrow at Haunted Stream are still stable!

I was up there about six months ago, snuck away from work to have a quick look and drove to the homestead to ask permission to fossick. The station owners really didn't know much about the fossicking and are happy for anyone to go. When I drove all the way back to the site I spoke to lots of people camping there, many of which hadn't asked permission and were under the general impression that the station owners didn't really want to know about the campers for fear of public liability issues. There are no real facilities there and as long as you take out what you bring in everyone is happy. Moonstone hill is incredible and definitely worth a look. Make sure you bring some descent digging tools and a quarter inch sieve. There are olivine bombs everywhere but to get the good stuff you need to dig and sieve.

Have fun :)

Ask a "Silly" Question / Re: Thin sections - for petrology
« on: June 05, 2012, 10:19:32 PM »
Your assumptions are correct, the polarised light allows you to accurately grind the slide by applying pressure to the thicker side as you grind. It really is an art form producing a good slide and that is why they charge so much when you send them to a lab.

Have fun :)

I used to make thousands of them when I was at uni, once the rock was cut to a suitable size for mounting onto a slide (using a diamond blade trim saw) I would place some apoxy resin on the slide and the face to be glued using an icy pole stick and then put them in a vacuum chamber in order to remove any bubbles. Once the slide had cured I would cut off the excess with a standard diamond blade (to a thickness of roughly 1mm). The slide could then be ground to a suitable thickness using grits on thick glass sheets. You will need a polarised light source so that you can check that the thickness is correct and consistent. After making a few you really get the hang of it, the trick is to hold the slide lightly with two or three fingers and grind in a figure of eight motion. Finally a cover slip can be applied using the same resin but be careful to place the slide by dropping from a 45 degree angle (again to prevent bubbles). The expensive part is the petrological microscope you need for analysis, a normal microscope isn't good enough because you can not cross the poles. I have an agreement to use one at the University and I am sure that you could come to a similar arrangement. Most people do not need in depth petrological analysis and I only make slides for work. You might find it handy to buy the Atlas of rock-forming minerals (metamorphic rocks and their textures or sedimentary rocks) in thin section depending on the type of rocks you would like to analyse. They are written by BWD Yardley, WS MacKenzie and C Guilford and retail around $70 each. Paul F.Kerr's "Optical Mineralogy" is an absolute must and at around $105 is definitely worth it. Let me know what you need analysed and I might be able to help,

Blue G? What is that? It looks almost identical to some chromite in serpentinite that I found at Coobina WA, I will post a pic when I get the chance,



Fossicking Locations / Re: Looking for Pegmatites
« on: May 27, 2012, 09:16:01 PM »
Pegmatites should be thought of more as a texture than a specific rock type. It is really a coarse grained granite which just means that it cooled slower than the surrounding rocks and therefore the chance of finding crystals is much better. Tourmaline, topaz, beryl etc occur throughout many granites but the crystals are so small that you can not see them without a microscope, when you get a pegmatite it is like having a magnified version of the granite so it is possible to find those rare volatiles (reactive minerals) in a more desirable form. Pegmatites can form in masses where the granite has had time to cool slowly or as veins that were injected into other granites and may contain cavities of large crystals. I hope that helps??



General Discussion / Re: buying the right vehicle for fossicking?
« on: May 25, 2012, 01:24:16 PM »
The Forester sounds like it will suit you quite well or even a liberty if they have all wheel drive. If you drive a car like that sensibly off road you will be surprised where they can go. Have you considered a Hyundai? I have seen a Tuscon? diesel off roader that looked very capable. I work in the bush and I drive Toyota's, Nissan's and Landrover's in very extreme conditions but I am sure that the Hyundai could get there if driven sensibly and I imagine it would be substantially cheaper. People are usually narrow minded when it comes to choosing a vehicle and it is very personal but I think so long as you have the four-wheel option you will get out of anywhere with enough patience, good luck and happy driving/prospecting,

Fossicking Locations / Re: Siderite at San Remo, Vic.
« on: May 25, 2012, 12:21:18 PM »
I used to explore for dinosaurs at San Remo with Monash University and the Museum of Victoria. The only siderite I found there was contained within the fossil wood itself although you did get some minerals that may have washed there from Phillip Island (mainly quartz and jasper). Siderite is quite soft and I have quite a bit of it so PM your address and I will mail you some from Broken Hill and around Newman WA when I get an opportunity (it might take a little while). For those of you into ultraviolet minerals the calcite that fills the veins around that area glows a vibrant yellow and sometimes peach.
