      Always honored that you look in on my videos. Great job on the Delamar video - I've not been underground there but was on the surface and did an article for the ICMJ a few years back. Not every epidermal sits on the ring fault of a collapsed caldera, but a surprising number do.

    If I obtained a "special permit" to pan sample &,or metal detect in and around the creeks & rivers of Yellow Stone- would I find placer gold? Just curious, like that would ever happen! More to the point; I've started exploring with Lidar and I found a Cinder Cone in a forested area in Washington State and I am wondering if it is a definite prospect. I was thinking of a metal detector and grab bags for samples to pack out as the nearest water wouldn't be worth more than 1 walk, So, I ask, in your experience, is there anything else I should pack for sampling because of weight concerns especially on the return leg? Share your wisdom Chris, you always do! I've subscribed to and still do to the ICMJ for years and reading all of your articles over the years I felt I knew you well enough to call you on a first name basis; I will be getting your book in November when the Monsoon's hit and I have time to read and research, work the spoils and plan for the next season all of which you are familiar with.

    • @ChrisRalph
      @ChrisRalph  5 ปีที่แล้ว +2

      Those basalt rocks, like the ones in Hawaii, dont produce any gold deposits. Too fast onto the surface and too fast to cool off. Its magma well below the surface that cools off slowly which has a chance to drive mineral systems for many thousands of years and create deposits. Glad you enjoyed the video.

      Some - not all - scientists think gold atoms are formed in Super Novas. The dust of the exploded super nova eventually gets caught up in the formation of other stars and their surrounding planets. The small amount of gold in rocks comes to the planets as the dust forms into a planet. Its the processes I talked about in that video which take the natural traces of gold and form natural concentrations of gold worth mining.

  • @ThirteenPercentHxC

    Is it possible to have a gold nugget that is not shiny? I have a bunch of heavy gold colored nuggets that look similar to some of the stuff in this video. They look like reef gold yet they're only shiny when wet. If I crush a piece and pan it I get a bunch of fine gold and very small coarse gold. Might they be epidermal deposit nuggets? because there are hot springs around here and I dug these out of a dry creek bed.

    • @ChrisRalph
      @ChrisRalph  2 ปีที่แล้ว

      Best of luck to you. However, there are lots of minerals that are heavy, lots that are yellow, and real gold looks metallic even when dry. I dont try to guess what minerals people might have, there are just too many possibilities. Also because I get a dozen or more folks every day who want me to look at their rocks and tell them what they have found, I cant offer a service to ID minerals and rocks.

  • @bbmw9029
    @bbmw9029 4 ปีที่แล้ว

    Chris, don't know if you're still watching this, but if your are, a question.
    Assuming there are hydrothermal deposits associated with some of the calderas formed by the now Yellowstone hotspot when it was back in Idaho, and that those deposits are still deep underground, how do you prospect for them? I assume at some point drilling is involved. But that becomes something of a game of Battleship, randomly poking holes around the edges of old calderas until you hit something. Is there a way to track these deposits down from the surface, so you know where to drill? Would there by surface features left by the old hydrothermal systems that could be spotted now, that suggest where the deep lode deposits may be hiding?

I'm not so sure their deposits happen in the same style though as this is more of a boiling hyrdro event and pipes are more of a magma that never get out of the earth and is in a slowly cooling event over an Extremely long time

      @@ChrisRalph a hot fluid has convection currents which stir the contents and the gold would be disseminated in the fluid until it starts to cool. when cooled enough that different elements or compounds can separate due to melting temperature changes; then crystals or masses can start to form. the higher specific gravity elements like gold should move towards the bottom and collect. in tight circumstances like skinny veins, gold seems to collect better than in large veins. why? some large veins are almost void of gold, whereas the small veins coming off the large veins have higher concentrations. at first glance you would think that the gold would concentrate at the bottom of large veins. at intersections of faults the minerals present changes and sometimes gold is concentrated. i can see this happening because of heat and pressure
      if it is high enough to melt but not enough heat and pressure are present in each fault by itself. subsequent fault cracking and filling might cause even higher concentrations of gold due to fresh input of gold bearing fluids and might even cause pockets to form. My main question is if the gold is disseminated in the fluid stage; then what brings each particle to bond with another?

      @@ChrisRalph - Cool.
      Not that it's of any commercial interest, but I'm fascinated by the -- anomalous I guess you could say -- macro-diamonds found in the Klamath and northern Sierra.
      As far as I can tell the host rock is still a bit mysterious. Weird subduction diamonds -- are they widely disseminated in the ophiolitic peridotite and weathering out of that, or are they hosted in some sort of ultramafic lamprophyre dikes, or maybe there are some lamprophyre diatremes that haven't been noticed?
      It would be neat to figure that out for sure. I'm guess they're just scattered in the obducted upper-mantle segments.
      Long story short for people who don't know what I'm yammering about: diamonds have been found in California and Oregon in gold placers, over the years.. Some good sized, and a _small_ percentage gem quality. The Old Timers probably tossed a lot of them out, thinking them an odd little piece of quartz. Interesting because they're not coming from your typical cratonic, commercial-type kimberlite or lamproite pipes, like you have in S. Africa and Siberia and up in Canada, etc.

    Hey thanks for your recommendation on this subject, I love learning about how to search for gold and researching information about known deposits in my state. As a boy my father took me with him to work a claim he and his friends had, I wish I had been older then so I could have gained some of the knowledge I have been learning the last few years. I have also been watching the hard rock mining , a man from AZ. And should I be learning his technique of panning because of the fine gold which is found here? He cleans up his fines pretty well.

  • @cacogenicist
    @cacogenicist 5 ปีที่แล้ว

    If I recall correctly, most of the _epithermal_ gold deposition in Nevada and California is associated with Southern Ancestral Cascade Arc Magmatism (rather than a hot spot) -- generated by subduction of the old Farallon plate.
    Interestingly, there is little or none of that in the Northern Ancestral Cascade Arc, which I think has something to do with the intrusions in the South being in cratonic basement rock, as opposed to the accreted seamount-type terranes in the north (up through Oregon and Washington).

    • @ChrisRalph
      @ChrisRalph  5 ปีที่แล้ว +1

      It true for Nevada and the tiny amount of epithermal mineralization in North eastern CA. The mother lode and bulk of northern CA gold is much older and of deeper orogenic types. There is a little epithermal in the northern Cascades but most is still too deep to be seen on the surface. A video on the gold deposits of northern CA is coming soon. Glad you enjoyed the video.

      @@ChrisRalph I wonder if there are epithermal deposits under the _High_ Cascades ?
      I forget how much longer the High Cascades have left before Cascadia subduction shuts down -- some day millions of years from now might be a decent place to look for gold. Especially if it gets some uplift to go along with all that basalt and andesite and tuff weathering down. Might be like a little poor man's Sierra Nevada 20 million years from now. :-)

      I am 1/8th Ausie - my great grandfather was born there in the Golden Triangle, but he emigrated to the US after his father was murdered for the gold and silver he possessed.. It sounds like what you need is a pulse induction type detector. They are made for very bad ground. When the ground is very highly mineralized it is tough in VLF type detectors, which includes the Equinox. PI types have a much better ability to ignore the kind of ground you are talking about. I have a Minelab SDC 2300 which I use in those conditions. Glad you enjoyed the video.

The cores minerals are transparent and transitional that are quite heavy as well, as well I having palladium element cores some of them look a lot like old asphalt but are indeed the element of palladium as well as the black brownish red Platinum cores rock that look like volcano Rock but our deed Platinum alloy.

I have Off line off the world internet witch had it's. picture illustration images of this orange yellow Sea Rock witch back in the day they called a meteorite.as well. The Platinum alloy metal is beautiful in this orange yellow reddish Rhodium rock core as you polish it it has a gold glow but the metal is beautiful whitish chromie platinum.. very beautiful Platinum Rhodium ' that looks to be a little oily. core of rhodium still has the red sea salts cakes to its pieces I break off as well as the yellow crust I would assume to be gold caked to this broke off pieces.but the metal is beautiful white chrome platinum alloys,Rhodium core has all it's specifications colors .to be natural uranium 235 they took this rhodium core off line .off line when I got some Attention on the world web about my rhodium core at 150 lb being exactly the same core of rhodium that was displaying for the world definition on line !!!!as they pushed rhodium to $30,000 for a single ounce. Even my broken pieces I polished into shiny chrome nuggets look the same as the ones that were online.i have a tool that fuses the outside core of these Platinum alloy rocks minerals.that puts divots into the Platinum core rock ,that leave a shiny metal appearance behind showing beautiful platinum alloy metal in your face depending on the color of the core the Platinum shades will be different .These minerals inside these Platinum as well as gold minerails appear to be clear almost invisible to see with the color of the core Rock to be platinum alloys..as well proving the entire rock core of mineral are platinum alloys....all these platinum'alloy cores. set in the same ancient ocean salt sea Waters that were concentrated in Platinum alloy minerals these minerals came from our planet core through erupting volcanoes that erupted into the bottom of our ancient oceans sea floors making every creature on the bottom of our ancient sea floor a host for the Platinum alloy minerals that were zorb like a sponge they slowly cooked in the sun rays for millions of years during the great divide of our continents that lift these shallow pools of sea salt Waters concentrated and platinum alloys minerals.. so where would a guy take these cores of platinum'alloy that are nuggets showing proof that they are indeed Platinum Alloys metal. all the way through their mineral core .rock that are worth their weight in Platinum alloy metal.and who would I talk to about having my tool manufactured and patented I called The wheel of Fortune disc for identifying Platinum alloy core Rock nuggets..,..this is TDK..
