Greetings!
Here’s a bunch of random rocks within 20 mins walk of my house, each from a unique area from the next. Mostly found while walking the dog through the bush and on the local tracks.
My question is for the big brain legends out there, if I was to spend time looking into an area or two which rock samples would be the most interesting lead out of these?
Just looking to get some cool pieces really.
What exactly are you looking for or wanting to know?
Lots of quartz bits there, a bit with munted crystals & maybe a bit of red Jasper. You in the Coromandal?

I think just an idea of what areas are most likely to turn up interesting rocks, mineralisation, crystals, or anything interesting or cool looking. Then I’ll spend some decent time hounding around those areas. South end of the Coro forest park 
There’s so much its overwhelming I’m happy just wandering, I should probably study geology a bit.
To be honest I think that people need to see the rocks first hand to give a definitive answer.
Seeing photos only can be very misleading but seeing them first hand can give a positive ID and also see features such as very small minerals that photos cannot show.
Totally looked like Coro stuff to me. Hence asking. I used to live in the area & cut my teeth fossicking all over the place. Don’t forget Kauri Gum as well. You are spoilt for choice in the Coro. There is cool stuff all over the place. Nothing quite like learning first hand by just getting out there & doing it. You will learn as you go. Like anything.

Some aussies with great ideas of how to test rocks for gold especially with quartz type rocks they build a big fire throw the rocks in until they absolutely glow red remove while hot and drop em into white vinegar the quartz becomes very brittle some bits ya can break up with ya hand in white vinegar the quartz often cracks apart where the tiny pieces of gold are so ya can see em, in normal water they just crack apart but much easier to turn to dust, ive done it a lot up nearly ever river between tekapo an chch but yet to find anything pick upable but theres flour gold in nearly every quartz rock ive tried from every river, but so small it can float even with dishwash in water, 35mm magnifier doesnt lie definite gold everywhere but chances of capture it seem very slim. Chris ralph geologist from usa has awesome utube stuff on rock types an how to identify em , but sight is the most useless identifier of rock or so he says , best he recons is identifying alsunite ie aluminium particles in rock, most with alsunite or the hundred other names aluminium particles have in mineralised rocks is best gold bearing identifier, but ya watch his stuff 20 times to understand a little of what he says lol, then once ya have learnt it ya find geologists today use pseunonyms to hide gold content,ie a report from 1975 on the port hills akaroa volcanos, which stretch from 11 ma to 6.5 ma ago apart. Lyttleton being the oldest ,8 different volcanic eruptions all pouring over each other 2 of which were strombolean eruptions the first lyttleton and the last stoddarts which both have potential to be gold bearing, but at least 10 geologists of different eras argue with each other through every report about the others having the timing sequences wrong and thats before ya realise all the rock type formations ya looking for rhyolites, balsanites already had so many different names and thats before 1975 when they started using extra psyenunoms to throw ya off even further. The guy who wrote the 1975 report skites about the pseunonyms covering up gold in his opening paragraphs ffs. Hard yakka this game i tell ya
