Thank you Katryn. Your video is clearly laid out and easy to understand. This really helps in my quest to develop the ability to identify minerals and understand more about our amazing planet. I can't thank you enough for the videos you've created.

[@StereoSpace]

Awesomely well made video. Great work. And the narrator is exceptional.

[@Caver461]

You've got some amazing pegmatites in California. Enjoyed the simplicity of your explanations - thanks.

[@-Laken-]

I love the detail and presentation of all of these minerals. Great for studying : )

[@cadsterdotcom4534]

Best video on minerals i have seen on youtube

[@mandymaurier5084]

okay. this is the video i’ve been looking for for months!!!!!! best rock ID video i’ve seen so far i love your explanations!!! thank you soo much!!!!!

[@EarthRocks]

Glad it helped!

[@Farida-A.R.]

Amazing information about identification of minerals all over the world. Thanks for sharing.

[@meredithgreenslade1965]

Excellent tutorial. Thank you. Just what I was looking for.

[@cosmichasm]

This is really good quality! It's paced fast enough that I don't get board, is slow enough to follow, and has useful information! Thank you and keep up the great work! I am eager to watch more videos from this channel. Like and sub!

Very nice to hear. Glad you appreciated it. :)

[@lucasguimaraespacheco9630]

Excellent explanation about the minerals. Very useful. I'll Watch again, sure. Obrigado pela ajuda.

[@lisafeck1537]

Mica family. I thought, when I was growing up, 30 years ago, that these flexible shiny layered rocks were called formica. Rock identification has not been a hobby of mine all these years. I have a 3 year old grandson now, my interest is renewed. As I was searching for information on this rock, referring to it as formica did not result in any correct examples. I'm very glad I found this content, my grandson and I will spend some time here learning more about rocks. Thank you.

[@megalonoobiacinc4863]

Where i grew up we knew these flakes as Kråkesølv, meaning crow's silver. Always thought they would work great as little windows...

[@johnwells1724]

Is there a video on the Metamorphic rocks? I learned more in the 15 minutes each in the videos I watched on igneous and sedimentary rocks than all the other videos I have seen put together! You're awesome. A sincere thank you...

Better than sector mass spectroscopy is XRD (x-ray diffraction) and a petrographic microscope. Spark atomic emission spectroscopy can also be used.

جميل أحسنتوم يااصدقاء معلومات مهمة نشكركم على المعلومات القيمة مرحبا 👍👍👍👍👋👋👋👋🌹🌹🌹🌹🌹

[@maujo2009]

How do we know a mineral exhibits cleavage by just looking at its faces _without_ breaking it? For example, Quartz has no cleavage despite the crystal exhibits several faces.

[@EarthRocks]

+Mau Jo You can't tell how it breaks unless you see broken surfaces. It's rare to see crystals with perfect crystal faces the way it grew (unbroken). So rather than break it, look for a broken edge. Telling the difference between a broken edge of cleavage vs. a crystal face (how it grew) is challenging, but you can do it! If in doubt, you'll have to break it. ;)

[@maujo2009]

Earth Rocks! Thanks! In case of Quartz, I can see how that'd work. But, what if the broken surfaces are smooth? I have samples of feldspar with somewhat smooth surfaces that look like cleavage (some of them meeting at 60 deg) and other surfaces that are much smoother and seem to be the actual direction of cleavage. How to tell in that case?

[@EarthRocks]

+Mau Jo Again, let me repeat: recognizing cleavage is tough. Everything breaks. And those breaks can be smooth or rough or jagged. But only if the break is along a flat plane is it cleavage. Smooth isn't part of cleavage. (Conchoidal fracture is a curved surface and can be very smooth.) Smooth vs rough is a texture. You can have smooth surfaces that are curved or flat or irregular. You can have rough surfaces that are curved or flat or irregular. To be cleavage, you have to have a flat plane. Some minerals have only 1 cleavage plane. Though you might see many instances of that plane, like pages of paper, you don't see them jut up against and meet another plane. I usually look at edges where planes meet, and if I can see multiple instances of the edge (like stair steps), it's usually cleavage. See if you can identify cleavage planes in these images: fog.ccsf.edu/~kwiese/content/Classes/MineralsFlashcards.pdf

[@maujo2009]

Earth Rocks! Thanks for your answer again. I would feel inclined to say from the images that the shown samples of epidote, plagioclase feldspar, actinolite, the dark sample of fluorite, pyroxene, chlorite, hematite, pyrite, graphite, olivine and serpentine lack of an identifiable cleavage.

[@EarthRocks]

+Mau Jo Not every picture shows what you need to see. But look closely at the garnet and quartz -- yes on crystal faces, no on cleavage. Fluorite, calcite, and halite pictures are examples where crystal faces and cleavage planes are the same. The minerals break along the same planes they grow.

[@ryanburrow231]

Out of curiosity, does anyone know where I can buy a set of these sample minerals? In college geology years ago, it seems we used this same set and am curious about getting a set for myself for at home teaching/learning. I know there are several sets when I look online, but can't seem to find one with this particular selection.

[@EarthRocks]

These particular samples come from many sources, typically purchased individually over years from mineral vendors at shows. Some were gathered in the field. They weren’t part of a kit. Kits, as you say, can’t replicate these, especially in size.

[@rickpicone9751]

Now I have this rock that is similar to your magnetite, compacted iron crystals, very heavy, magnetic, black, melted look on the outside, but it streaks red from the window I ground in it.

[@EarthRocks]

Hematite most likely. Post a photo.

[@coolercat4027]

Is it pure black or dark brown? If it's dark brown you might have Limonite

[@rickpicone9751]

@@coolercat4027 Black on the outside cause it looks like it been melted, inside silvery crystals, very magnetic, very heavy.

i wrote sometimes ago about the mineral industry in pakistan.our gems are sent to chhina and other countries.we must give job opportunities for our native inhabitants.for this purpose government ask the saudi or any other country to install factories to refine the ores of the gems. G overnment must make this industry as a part of its portfolio.other minerals as the people and government knows it gold copper iron must be taken in consideration. thanks agha irfan ahmad
