ste="im1badpup1"]I can say because ive researched the geology of the area from its original volcanic formation and vents mapped out. The secondary igneous intrusion zones later on and vents with faulting zones are mapped too. Some are hydrothermal although on land now. Theres a raised beach or theres hydrothermal exposure on there pegmatite dykes and weathering. The quartz vein deposits are in places exposed. Theres garnet, pyrope in some pegmatite deposits. Theres sappire around some other volcanic activity. Its stipulated conclusiv7ely in the scientific papers that the sulfides and some tellurides in areas what have formed in so called hot zones all have a ppm count for gold some other pgms in one intrusion belt. The sedimentary sulfides contain no pms. Theres partially metamorphosed red sandstone containing a gold value.
Theres been godnose how many iceages but ive read the mapping data of glacier flow direction for the last 6-8 glaciers their terminal point etc.
So most of what i say as fact isnt my words its a conclusion from literature ive read. Id still be scratching my head lol.
The alluvial gold no mother lode source has ever been verified. Theres at least two sources unknown for the alluvial gold.
The mining been done historically in the area excepting the alluvial recovery has been for the telluride and sulfides and gold recovered from that. Theres been no motherlide veins of native gold discovered historically afaik its all from sulfides and tellurides.
If it was made to sound like i was stating that the sulfides i have are from a specific quartz vein only with 1800ppm au reading i never meant that. That same vein has wildly varying values as it runs exposed across the country down to just several ppm. The sulfide content dips inline with the au ppm drop.
I still dont know if the ppm values are for a batch of "quartz vein ore containing sulfides the sulfide content 5-8% with a value of 1800ppm" i think ive looked at such a wide range of historical testing data, methods used i cant make a true conclusion from it and the only way to know what the erratic sulfide deposits contain is to test them myself. As you say warmgold theyll vary in composition from place to place ive noticed already several things about the concentrated deposits in different areas. Different materials dominate. Arsenopyrite in one spot. Garlicy smell.
I dont know what the acetic acid smelling one is yet though.
Theres a lot of lead and silver mixed ore deposits too.
That lead in my picture should have an unusually high ag content if history is correct itll be interesting to find out. Not profitable but im primarily an amateur chemist so its interesting to me still.
Think of scotlands geology. Thats the source of most of the material im dealing with.
Id like to isolate and collect some rare platinum group metals for my element collection at some point too.
Anyway my cubes arrived! Off to pick it up and prep it for tomorrow
Edit the cube arriving. Its at a delivery hub in transit. Damn.[/quote]
Hello
What do you mean with been mapped?
You intend a geological map of the area? In which scale?
Hydrothermalism don't mean always gold (not in quantity to call it a deposit, in 0.0X ppm the gold is everywhere on earth/sea)
But the document you found have to be considered.
In the first or second post you wrote the vein contain 50 ppm of gold (or 50 grams ton, if I don't mistake with numbers) is a rich deposit (and in reality, probably is more richer in a good spot)
is this correct?
You said"I come to this conclusion by my own etc": geology is most based on conclusions, very few of it is been demonstrated scientifically (it's hard to repeat on lab for example the mountain creation process :mrgreen: ) so it's good considering "every" conclusion
Read the glacier texts again, its important , they could have taken some of the alluvial gold (coming from "who knows) in the territory. You can try with sluice box in the area where glacier have placed the sediments carried during his passage ( a big alluvial gold spot, obviously the glacier must have carried gold veins in his passage..)
U can check for the big areas in a geological map (marked as glacier alluvial deposits)
I think you will find, checking the internet, if the glaciers on your zone carried gold...they are big geological movements that interact with huge part of land/world
And in millions of years they concentrated the gold (and heavy minerals/metals)in alluvial deposits, in everypart of the territory they passed on (obviously the ratio of suspected gold varies, and can be null in some deposits, a lot should be considered), so I think it is noticed on the web
Why are you saying there are two unknown source for alluvial gold?
And how you have detected silver and lead?
The acetic smell I don't know, could be something organic... here in the forum there are users better in chemistry than me(A LOT better, scaring sometimes :shock: )
