I thought that your presentation was very helpful. I am an on-line college student in the Atlanta Georgia area who is preparing for my first GEOL mineral lab. I appreciate your video as it gives me a pretty good idea of what to expect when I walk into the room this week. Thank you.
This was very useful to show my son during our homeschool Geology lesson today. He's very interested in Geology and can't wait to have a nice collection like yours.Thank you for taking the time to make this video and for sharing it with us :)
Thank you for your video. I'm not a school room student but, I'm a prospecter of Hematite for jewelry. I'm suddenly acquiring many rocks that I can't identify including fossils. So these identification videos are great learning tools. Thank you again for a great informative video. 💗 Ms Michal
Your comment made me curious if you had any good rock hounding, lapidary or other useful videos in your playlists. So I clicked on your thumbnail and and looked for myself. I've created my own playlist of your public playlists, I'll remove the black/white movies later, lol, since that's not my cup of tea. So thanks for your variety of rock hounding, lapidary and OTHER videos for me to explore. Great taste!
Thank you for this video. It helped me review for my geology mineral identification test. I liked how you just did brief descriptions of some of the most easily identifiable characteristics of each.
Hi, I travel across Canada a couple of times a year, and I like stopping at mine sites, and dimensional stone (tomb stones, counter tops) places. They usually let me look around their scrap piles. I also purchased some at science shops, rock shops, scientific supply places.
Thank you for this video- I just ID ed the 2 stones I found in my yard. They are copper !!!! So pretty!!! I live about 10 miles as the crow flies from Stone Mountain Ga. Always finding beautiful stones. Lots of quartz
A few corrections: 1) Your apatite is actually grossular from Lake Jaco, Mexico. 2) Bauxite is a rock, not a mineral. 3) Cinnabar is mercury sulfide, not oxide. 4) The second copper is natural, not a smelter product, from Michigan. 5) Your hematite ring is most likely a manmade material. 6) Malachite is copper carbonate, not oxide. 7) Quartz is not glass. 8) Your smoky quartz crystal is an irradiated crystal of formerly colourless quartz, from Arkansas.
Glass and quartz are both SiO2, but glass doesn’t form the same hexagonal crystal structure because it cools much faster. Glass typically has other things added to it (such as potassium) to lower its melting point. So in a sense, quartz is glass, because they have the same chemical makeup.
Incredible Presentation! Is this really HS Geology in British Columbia, Canada? WOW American schools are so far behind! Even if there are some inaccuracies, it's still better than most things I have seen online.
I really like your video. I've had a geology class last session(in Québec) and saw some mineral and I wanted to get a list of the most commons and their English names and you gave me a nice video perfect for what I was looking for! Ty
Well, there's only so much you can say in an 8 minute video. Maybe one day I'll do a separate video for each mineral. There's a lot to know about each mineral. Someone else asked about uses of each mineral, and yes, most of these do have uses in industry, but again that would be a very long video.
Please do more videos. On the minerals. I want to study minerals and rocks and prospect for gold on my free time . Its intruiging. I love it. Please ....make more
I am new to all this, but have a growing interest in mineral identification and found your video very interesting. I live on a tropical island and would like to know what types of minerals can be found on tropical islands.
Hi, If you're on a coral atoll, there might be no minerals other than shells and coral. The rocks made entirely of shells are called coquina. Volcanic islands might have zeolites, which come in many varieties, and contain rare earth elements. Maybe olivine, which in large clear crystals is commonly known as peridote.
Hi, I have a big piece let say of rock/glass, heavy, color green emerald like with one rough white side, not sharp at all, it has many uneven cuts. It look like Tzavorite Garnet or Emerald, I bought it from an estate auction as a gemstone with other stones and I really want to know what it is exactly. Thanks for your help
Hi star, there are message boards and forums (I believe there is also a sub-forum on reddit) where you can share pictures and give exacting description to find the the most accurate identification. It is more difficult to identify when not in person but there is specific criteria for identification of any stone. Check out a gemstone or mineral forum and they can help guide you.
Not a problem. The internet is a treasure trove of information but, just like when finding gemstones, it helps to know where to dig XD Let me know how it goes.
@@op5814 bro you have no idea what I did or didn't learn from this video. I leave a positive comment and you want to trash it for no apparent reason says alot about you though...
I would LOVE this class! Your teaching method is probably very effective; the associations, etc already took root in my mind after 8 minutes. Thanks :D
Yes, this is just out for this video. It is kept in a sealed container normally. When not abraided or played with, the fibres usually remain intact and don't enter the air.
Yay I recognized most of them from my geology class. I also mentioned that k-feldspar looks like meat with the striations of potassium running thru it. Nice job.
Actually, he said k-spar looked like horse meat. I actually was taken aback by that because we do not eat horse meat in the United States. Is it/Was it common in Canada?
We sell Rough Diamond USD 400 per carat VVS D-color, we are currently in Namibia, southern Africa. Do you perhaps have a network of potential buyers you can refer us too. mopmining@gmail.com
Thank you so much! I got a storage unit with many of these, some polished rocks, jewelry making. I want to ebay them but don't know the names of all of them.. This is helping out!! wish you could look at my photos and tell me :)
the copper samples were both from under ground mines or ore piles. not from a smelter. copper in upper peninsula of michigan is almost pure form.some pieces can go many tons.
Asbestos is an alteration product (hydrothermal alteration) of olivine. It is related to talc, and amphibole. It is quite common. Caused by metamorphism of mafic igneous rocks, which cover most of the Earth's surface (oceanic crust is made of mafic igneous rocks).
The basic building-block molecule of quartz is silicon dioxide, SiO2. However, when the SiO2 molecules are attached together to form the quartz mineral, it is in the form of SiO4.
Was listen ,,but did see no meteorite ,do you have any ,if so please video it ,,,I love the way you teach a person is sure to learn,,,good job thanks for sharin ,,,
Walking through the woods (in New York), I came across a large amount of very, very shiny, glasslike rocks. I picked one up, and hit it with another rock and it fractured very easily into a little shard. They are all deep black, and working with them leaves a black residue. I took some of it home with me. Any idea what it could be?
You're so awesome for getting back to me. It's clear that you know waaaay more than I do about this kind of thing, and maybe it is ok to say that glass is quartz, but quartz is not glass (super simplified). I'm afraid you will have to dumb down your explanation to me because I am not well educated in this subject. Thanks for this video. I'm trying to decide whether I want to get into the rock side of jewelry. I've had some metals classes at univeristy, but I like rocks too.
Hi, I think you mean "glass". Yes, it is largely made of quartz sand, although in many cases, other minerals, or elements are added to give glass different properties. For instance, boron is added to make glass heat resistant (Pyrex glass). KMnO4 (chameleon mineral) is added to make purple glass. Addition of gold III oxide, makes red glass.
Just a suggestion.. on basic identification you should begin with a hardness test. This basic test will rule out what the material won't be and put it in a category more close to what it really is.
Very cool. I really like the green and blue coloured rocks, imagine building a house with them! I wish the camera focused a bit better though, it did the video injustice.
Hi, I would guess that it is an igneous rock type called Gabbro. The black residue would just be the oxidation product from weathering. New York is in the Appalachian or Laurentian mountain chains and there are many mafic igneous rocks. Gabbro is kinda like granite, except black.
Oh right, thank's for the reply. How common is it in the environment? Hows does it form? Seems like quite an unusual mineral given it's fibrous composition.
Can Gabbro be really glossy? I just took out a chunk of these rocks and cleaned it with water and an old tooth brush. In the process, I noticed that not all of the rocks have a black residue, and the ones that do have a very small, but visible grain. So do you think those would be gabbro? There are a few that have no grain to the naked eye, and they are really shiny and glossy. I'm thinking about trying to grind it into a marble or something, they look awesome.
Thanks for your vid. I have a question and don't know if you can answer it. Of which mineral/stone family gives off the most spark/energy when striking each other? And which one mostly absorbs energy? If you don't know what would be your guess? I have seen a video that if a certain stone is used with copper it can create energy.
I'm not entirely sure I understand all your questions but I do know that flint stone and steel (or any iron based metal/mineral) is what is used to make sparks and ignite fire. As far as stones that absorb energy, nonmetallic ceramic like stones, like talc in this video, are probably the best bet there. I believe asbestos is also very insulating but I wouldn't recommend it for any science experiment you're gonna try at home. Or if you mean absorb energy as in carry/conduct it, any common metal mineral will work. With zinc, gold, and copper being among the top. Sorry I can't help much more. I suggest searching google for "the least conductive minerals" or "conductive properties of common minerals" for a better shot at finding the MOST conductive and insulating minerals.
Glass is made from quartz grains (sand), heated until it melts and then cooled quickly. Because it is cooled quickly, it does not develop a fixed crystalline structure. However, quartz cools slowly to develop crystals that do have a crystalline structure. Natural concurrences are volcanic glass obsidian which is formed from felsic silica rich lava which cools quickly to form glass. If it cooled slower, it would form the mineral rhyolite.
Underground exploration is a huge industry. Yes there are many ways to locate and identify underground minerals. You could do an entire degree in that at University.
Hi, individual minerals are pure chemical compounds. So in that respect, yes they all have commercial value. If you can mine the rock/ore and isolate the individual minerals, you would have pure chemical compounds for use in many industrial applications. That's how we get many of the chemicals that you might see in a lab, or pharmacy.
blunosr, after watching this, I feel many of my found gems I have 'found' out west are mere imitations of the valuable gems. Yes I went to a tourist attraction place that claimed we could find gems. But, my question is this, I live in Western New York do you think any gems or valuables could be found in creeks and rivers?
There is wonderful fossil hunting in the Hamburg area. Gems and other minerals may be tough to find since you are in a sedimentary region. Try taking a weekend trip out to the Adirondacks, that is where you might be able to find the gems you’re looking for.
Hard to say without seeing them, but small smokey quartz would appear to be transparent. The larger they are, the darker grey or black they would appear.
I found a rock whilst on the beach and I noticed it was shining. So I picked it up and there was a little hole and inside I could see some light orange shining crystal formations. On the outside the rock is mottled grey and quite smooth. Could you tell me what it is?
Hi, if what you mean by "points" is arrow heads, they were made of many things, most of which were bone, or rocks, not minerals. I suppose you could use quartz though. Good arrow heads can be made from obsidian, or chalcedony (chert/jasper). In fact obsidian is still used today for some scalpels in very fine surgery, like brain surgery. At least, that's what I'm told... Obsidian can be made sharper than steel.
