Best informational channel for my rock hounding 💯 Great voice too!

[@oscarmedina1303]

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.

[@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!

[@k.chriscaldwell4141]

This is a superb video. The best presented and most thorough. Thanks.

[@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...

The tables are in lessons that are built around the videos. To access those, you need to join the channel (become a member). :)

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

[@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.

[@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.

[@EarthRocks]

Looks like you have pyrite, galena, and possibly chalcopyrite and/or sphalerite. I don't see the purple mineral, but a cubic transparent purple mineral sounds like Fluorite (which will fluoresce to a different color in a black light). Hope that helps. Nice find! :)
