thanks for this video, you cleared a few things up for me that my mind was having a hard time grasping, you explain very well, wish i would have stumbled upon this video long ago!
I'm new to minerals, and I've found some incredible specimens (at least for me). Unfortunately, I went out many days in a row, and I brought home bag after bag of minerals. Of course I was looking for crystals, and I did find many fine specimens (nothing like pointed quartz or anything), then I learned a little bit about agate, and began bringing home everything I found. I made the mistake of not learning about minerals before collecting them. So I'm stuck trying to identify hundreds of minerals with almost no knowledge of them, now I'm trying to catch up, I'm really in a predicament! I also have no real tools for this, like a rock tumbler, all I have is a hand held rotary tool. I'm pre 101 in minerals, but I'm trying, thanks for the video!
Good job sir... very clear, concise explanations... you might want to mention the Moh's scale of hardness... it is the primary test for mineral identification
That big slab of brown Mica is impressive. I have lots of sizes of Mica but if I found one that size, I think I'd have to sit down catch my breath for a moment. :D
Jenn P If you find that big slab of brown mica is impressive, then phlogopite, which can be an indicator for diamonds, will smother you with wonder! It is more of a copper colour and, as you turn it around, fire seems to leap out of it on its cleavage!!
@@tyleratkinson4354 No. But I've picked Quartz as a simple example because it's one of the most common Rock Forming Minerals of the Earth's Crust, in Geology, Quartz mineral being a semehow more 'pure' form of syllicate (Quartz formula: SiO2). Sillicates are a very large group of minerals which are often dissolved, in geology related laboratories, with Hydrofluoridric Acid. Carbonates (which Calcite is a common example mineral) are often dissolved with Hydrochloridric Acid. And Salts (for example, Halite mineral, which sometimes may form rock layers) may be dissolved, I guess, with Water.
Hi Netyote, Calcite will cleave into Rhombohedrons and also effervesces readily when Hydrochloric Acid is applied to the specimen. Halite,is naturally forming Sodium Chloride (table salt) and forms in cubes. They are both either clear or cloudy white with obvious cleavages.
Some incorrect information in here.. Both amphibole and pyroxene can be many different colours. Amphibole cleavage is 56 and 124 degrees. Glass is made using quartz not from quartz; glass is actually amorphous. Muscovite has a white sheen - it used to be called white mica. Phlogopite can be pale brown but with yellow sheen. Brown mica is not diagnostic of muscovite.
This was an excellent explanation of minerals etc.
Great straight forward video. Great samples.
Thanks a lot for this video! If you ever do another like it, you might address how calcite and halite can be confused.
Great video! Very clear explanation of all the different types of the stones and individual classes a stone!

I have stones that attract magnet, I believe its a meteorite. Any one who can buy here
Okello Aaron Nevis ㄡ

THIS cleared something up for me...loved it....Thanks!!
Great vid. I could never tell gypsum, fluorite or halite apart.

Quartz will react with acid too, provide it is hydrofluoric acid.
Must specify which acid being used.
Thanks for the video.
Did you mean calcite?

Extraordinaire 👍👍👍
Totally watched this before my lab!
Its looks very good
Great video thank you
Great Video, but please use a 1080p camera so we can see the textures on the rocks
Supersumukh M this was in 2011 lol
woops :)
Superb!
I wish you were still uploading

What is cleavage in crystals mean?
Great video, thank you very much.
Thank you! Very informative!
Beautiful..
calcopyrite is often associated with quartz, usually milky or clear quartz.
Frank Reiser M.S. In Australia, we pronounce this as CHALCOPYRITE!
thanks ! good , now i know i have a transparent calcite Rhombohedral piece,
When I learnt these minerals, the "Ch" in Chalcopyrite was pronounced as "ch" in "church"! Perhaps it depends on your location!
Thanks bro👊
I have a couple Stones not too sure what they are when you look at them you think it's black but it's really Brown
What are you referring to when you talk about cleavage??
Thanks,good info.
Wow nice
This web was by TBBM-CaoDai.
which one contains daimond ?
I dont think any of them have diamond, if youre asking because of the shiny bits in some rocks, thats mainly quartz and other minerals
شكرا لك علي هذه المعلومات
Nice video, but everytime you make a s sound the whistle hurts my ears lol
thankyou sir
My teacher sent us here.
I can't hear you say please be a bit louder and clearer thank you
👍👍👍👍👍👍
dope
😍
Hy mach
❤️❤️❤️🙏🙏💎👍👍🙏🇻🇳🇻🇳
Focus your camera
yes please
not in focus!
👍👍👍👍👍👍
