Geology 5 (Igneous Rocks)

Glad to have you studying with me! I have more content in the works and I hope you'll enjoy it. For those that are interested, the best textbook out there is this one: amzn.to/47VNed8. However, it's a little old now (two of the authors have passed away) and if you prefer a newer textbook, I would recommend this one: amzn.to/45UFDcR
For other introductory geology lectures: • Introduction to Geology
This lecture video covers the main categories of igneous rocks present on earth's crust. It's been arranged for anyone who wants a deeper knowledge of igneous rocks and the environments that create them. I hope you enjoy it! Closed captioned.

I am a biology teacher here in the philippines and I am starting to learn geology on my own. Your videos greatly help my self-study.

[@lavalady5097]

No sleeping. Totally facinated. No matter how many videos or online courses i do about volcanoes and igneous rocks i always find something new. I guess it facinates me cos i live in reykjanes peninsula which is basically volcano heaven mainly basaltic fissure eruptions, but we have composite volcanoes in iceland. Having said that in spring we had a very friendly non explosive volcano erupt and we got to go and explore that often. It was so amazing Its got me into this side of things. Love your videos thank you so much :)

[@EarthandSpaceSciencesX]

Thank you for your appreciation! It is my goal to visit Iceland soon and see the volcanoes in person. I also have never seen the Northern Lights...another thing I desperately want to see when I visit.

[@sluggou812beotch]

I'm really liking this course. I took hydrogeology years ago and I'm taking geology 101 on KZbin with nick Zentner right now. I'm 58 and can't figure out why I waited so long.

[@EarthandSpaceSciencesX]

Glad to have you with us! Hope you enjoy the content.

[@Mickeycuatropatas]

I'm 57 and for some reason, I love geology now and starting a 3D terrain map company so I am really interested in the formation of mountains.

[@gauravchandak8748]

I am an MBA student, not in any remote subjects. i have anything related to geology, yet I am here binge watching every part of this series, hoping to retain at least 50% of this so that some day I could help my kids for thsi subject.

[@cowboygeologist7772]

Even as a retired Geologist, I enjoy watching these videos.

[@brucewinningham4959]

May I ask which field of Geology did you work in Sir? I am just a "wanna be" Geologist myself. 😊

[@cowboygeologist7772]

@brucewinningham4959 pretty much all of it. Worked in remediation, compliance, site assessments, groundwater, engineering, structural, monitoring, mining, flood control, stabilization, emergency actions, education... Most Geologist do not do just one or two disciplines in geology.

[@InstrumentManiac]

I'm in the process of studying for my PG exam and your video series have seriously been a vital tool. As a hydrologist I didn't get much of a geology background which makes trying to jump in confusing. The way you lay out and explain all of the concepts and link them together through these videos has been fantastic. Thank you for all of your effort putting these together they are definitely appreciated ⛏️👏 Geo legend!

Hope you did well on your test! That's exactly why I am here too.

[@davidyancey2807]

I failed my mineral identification exam. I took everything for granite.

[@TwylaWorld]

I'm an avid hiker in Northern California and I am amazed by the beauty and grandeur of the amazing rock formations in the Sierra Nevada. I come across huge volcanic boulders on my hikes... I always thought these were blown from a volcanic eruption, but now I'm thinking they came up from below? I've decided to go back to "school" via youtube and books to study Geology. Thank you for these wonderful lessons!

[@MogusMasterSaikawa22]

Wow that’s so awesome !

[@CommanderHayes]

My motives for watching these videos are exactly the same.

[@vivian19203]

Wow I have learn so much from your videos in 3 days than what I study for 6 months on college. Thank you, Thank you, Thank you.

[@EarthandSpaceSciencesX]

Wow, thank you!

[@ryandroveway731]

I can't thank you enough for taking the time to make these wonderful tutorials.

[@Magurae]

I studied geology as a minor subject in university 20 years ago, but didn’t understand a lot. Now I see why, because I didn’t understand the basics, because they haven’t been taught to me in the right way. Thank you for these lectures!

[@EarthandSpaceSciencesX]

I’m really glad I helped you out. It really makes my day to get comments like this.

[@naturalistthar8342]

Very engaging lecture. Didn't even blinked my eyes. Can you please make a lecture on Welded tuff.

[@rickmessina5396]

Fascinating presentation. Will you have any info on geology and gold.?????

[@EarthandSpaceSciencesX]

I do discuss it a bit in my metamorphic lecture, but not in much detail. Perhaps that is a good suggestion for a future lecture.

[@cookiemobster4577]

Hello! Thank you for these videos..... I am watching SO intently!!!! I am the biggest dork about rocks!!!! I live in Lincoln County Ga which is on the South Carolina border. We are on Clarks Hill Lake, in a place called Indian Cove. It's called Indian Cove because in the 80's the government did an archeological study here in the neighborhood at Indian Cove where they excavated 6 different Indian Mounds. Besides that, there is a place here called Graves Mountain that is a geological anomaly. It used to be a volcano and it used to be owned by Tiffany and Co. because at one time it was the worlds largest producer of Rutile. In addition to the Rutile, there are about 40 something other minerals and semi precious stones at Graves, including iridescent rainbow hematite, lazulite and azulite! That combined with the Native American artifacts that we find make for some REALLY great rock hunting. As a life long rock hound, I am in HOG HEAVEN here. Actually that's the main reason why we landed here, 3 hours away from our home town, the ROCKS!!! I have soooooooooooooooo many different things that I find here that I have never seen and some of them are reoccurring over and over. I am not sure if some of these are just the way this rock breaks or if these are artifacts..... For instance I have over 100 rocks that have HUGE V's at the top of them. Folks say they don't have tool marks, but I just don't think I am finding all of these with breaks that don't run with the "grain" of the rock. I need someone to help me!!!!!!!!!!!!!!!

[@CanadianGoldMining]

I am a prospector for a geoscience company .. These lecture have been key to furthering my knowledge of minerals and rocks and helping me in the field !!.Thanks so much for sharing these lecture with us !!

[@GuyMassicotte]

I can listen to you all day. Very well done, informative, just perfect. thanks you so much for your video's 👌👌👌👍👍👍👏👏✋

Isn't it? Got into this through hiking. Now I'm rock obsessed and just bought a rock hammer.....

[@fulanfulan6011]

Thank u, a Great tutorial of geology, nice pictures, I enjoy it... good job

[@jp216]

Besides the light color, how do we know these are quartz veins in min 14:48 ? Do geologists need to do the tests you mentioned in your last video, or is it obvious by just looking at them? And can we see feldspar veins in granite? Thank you

[@SIMONMEVANS]

Great stuff thanks. Btw, you mention the term metricaly challenged but there are many of us who aren't familiar with feet and inches out here....

[@EarthandSpaceSciencesX]

When I recorded this originally, it was targeted for a small class (around 14 if I recall) of exclusively American students living in Hawaii who had next to no experience using the metric system. When I put this lecture on KZbin, I never imagined it would reach an wide international audience the way this and my other videos have. That’s why many of my videos are scheduled to be updated, to accommodate my international viewers by using both systems and improve their value for everyone.

[@colubrinedeucecreative]

Fascinating! Thanks!

Hi you mention a book around 11' - could you give the reference ? Thanks for the fantastic courses !

[@awesomehamido6396]

great job nice work but can i ask one question at 22:44 in the video u said they all have same chemistry but i see the rock beside granite is basalt is that right or is it another type of rock thank u very much u really doing awesome videos keep on the nice work

[@getzvalerevich6565]

Loved it. Thank you

In US, are these lectures being presented in high school? By the way, as a Turkish guy who loves geology very much I really like your videos, thanks for all this stuff :)

[@EarthandSpaceSciencesX]

I have made them available to anyone who wants to study them worldwide. :)

[@sabrinafelber]

Igneious rocks! Thank you!

[@brucewinningham4959]

Other than NaCl, what rocks without CRYSTALS contain only the two required "atomic" minerals? But NaCl contain Crystals. May I assume if it comtains less than two (which is one) minerals, it would only be an "atomic" mineral itself? Since a rock needs to contain crystals before it is considered as a GEOLOGIC MINERAL, does it need a certain number of Atomic Minerals before it is considered as a Geologic Mineral. I am Sorry if I am using the terms "Atomic & Mineral" incorrectly. Am I incorrectly assuming that NO rocks can form Crystals without the necessay Heating & Cooling?

[@jowalnab9498]

i ❤ igneous rock, thanks for da lecture

[@EarthandSpaceSciencesX]

You are most welcome!

Great video series. Where did you get the charts from? Are they from a book?

[@robert-wr6md]

That was great.

[@EarthandSpaceSciencesX]

Thank you!

[@williamlohrmann2021]

amazing!

[@insertcreativenamehere7377]

Aren’t there rocks out there that only consist of 1 mineral?

[@EarthandSpaceSciencesX]

Technically, those are monomineralic substances. However, the term “rock” is frequently used when discussing them, much like how obsidian is also called a rock (obsidian doesn’t even have minerals...it’s quenched glass), so the scientific definition doesn’t always match the common usage.

[@insertcreativenamehere7377]

Earth Science X fair enough haha thanks. That diorite looks more like cookies and cream than anything else 😂

[@kiliosai]

Diorites are commonly termed as "Salt & Pepper".

[@ThatRemoGuy]

Thanks a lot

[@waoweMan]

Thank you very much.

[@Dumchi22]

I have seen some Igneous Rocks classification charts with Muscovites just above Biotites. While in this video it is shown on the top left. Does it make any difference?

[@EarthandSpaceSciencesX]

Not really a major difference at the level of an introductory student.

[@jasonsspecial]

Beautiful thumbnail !

[@nibiruresearch]

I know of a blind spot in the education of geologists. When we look at the many horizontal layers that we find throughout our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata of India and the Popol Vuh of the Mayans and others. They tell us about a cycle of seven disasters. Certainly, regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of wet mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals, gravel and meteorites. That mud layer hardens and becomes a new horizontal layer on top of many others. The disasters also create a cycle of civilizations. To learn much more about the recurring flood cycle and its timeline, the re-creation of civilizations and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9

[@joedonovan2405]

Is Diorite a type of granite?

[@EarthandSpaceSciencesX]

While both granite and diorite are intrusive igneous rocks that can appear to be similar in texture, each type of rock contains a different set of minerals. Granite is typically made up of quartz, potassium feldspar, and plagioclase whereas diorite is typically hornblende and plagioclase with no quartz or potassium feldspar present. Hope this helps...

[@joedonovan2405]

It helps a lot. Thanks for the clarification.

[@josephe9013]

@Jack Fienga bruh it’s been 4 years and I finished by degree already lol

[@carmineredd1198]

what is chert

[@PhilStinnet]

In Sanskrit, Agni = Fire. Igni and Agni seem very close to each other.

[@EarthandSpaceSciencesX]

It would not surprise me to find that they share an ancient origin. Thanks for brining this up.

The rock with no crystals is called "obsidian."

hello , what book you used in this video?..good lecture your very calm and very smart

[@sonarbangla8711]

Besides temperature, pressure and volume quantum mechanical effects decide the nature of various igneous rocks. In order to explain the various rocks may prove impossible due to decoherence.
