I'm a retiree who first discovered geology during my junior year of college in 1980. I was fascinated by the field then and is still fascinated by it now, esp. with all the new discoveries. These lectures are presented so clearly and with so much enthusiasm! They bring back some very fond memories. Thank you.

After (binge) watching the series so far, I must conclude that this is the best and most in depth introduction to geology I have come across. The structure is brilliant actually, giving a great insight into the processes from the very start which makes it so much easier to understand and reproduce for practical purposes. Really enjoyable.

I'm taking geology online right now and theres no lecutres, just readings and i really appreciate how detailed this is

Mind blown! I'm definitely going to watch part 3 and 4 again to let it sink in further. This is the first time I'm motivated to look more into chemistry/psychics as I had no interest in it at school and did very badly in those areas.

PART 2: I have prospected beautiful minerals at Sterling Hill Mine, the dirt recycling center and collecting dimensional stones, such as mall rock mulch which has beautiful granites with calcium or quartz veins in them, muscovite mica books and schists, granites with large schist, orthoclase, shale, slate, marble, chert, and even vesicular basalt from a road cut. I love your course. Frank Reiser M.S.

I think this is absolutely fantastic

When the Doc is discussing Mineral collecting kits - who has made their own using a Whitman's Sampler box? I must have made a dozen of these when I was a kid I had so much fun collecting rocks and minerals. Unfortunately, no internet back then - but trips to the public library to learn about the sciences. 50+ years later - I still have a couple of those kits

PART 1: I got into becoming a major rock hound by first finding a good15 pounds of green aventurine while walking my dog in the cemetery. Then, walking my dog again in a dirt recycling center, I came upon a rock pile that had beautiful specimens in it, including a little citrine, amethyst and teeth quartz. That got me into studying rocks and minerals, but I realized that I was not knowledgeable enough to identify rocks and minerals. So, I studied all of geology for 7 years.

Want to bring to your attention that at 14:50 you meant to say that quartz is 2.7 times heavier than water. Great lecture. Thanks for sharing.

Am I mistaken or when he goes over the colors of minerals and points out that there are orange minerals, isn’t that an orange citrine Quartz Crystal piece on the upper right that he labels as a stained piece of a type of rose quartz?

Would you mind sharing presentations? It would be excellent for the audience. Kind regards...

What a fascinating subject! Thanks for posting this wonderful class on Geology. Gold, I was told it cannot be formed here on earth. I was told it can only come from a star going supernova and a meteor carrying it from that supernova coming here to earth. But in your video, it looks like it grows on quartz? I will believe a geologist over an astronomer. Hope you can answer.

This stuff can Heal you.

Great Lecture. Can you share the presentations?

Interesting AF!

I'd be quite interested in doing some chemistry and modify minerals to get some interesting properties and colors, I wonder whether people do this, or are simple books to get started Just a minor detail but in 49:55 (OH)2 is not water, but hydroxide, i.e what makes compounds basic.

Thankya. I feel smarter already, always wanted to know.

I'm sorry, in a book that I'm reading "Essentials of Geology" 5th edition, by Marshak, it says that 35% of the Earth's mass is iron, and barely 15% is silicon. Is your chart during min 20:00 only referring to what's visible on the surface?

For the composition of the earth you were talking about the crust and not the whole earth, but you didn't precise it And if I'm not mistaken put's the Iron at ~30%, the Oxygen at ~30% and the Silicon at ~15%

Yes, I was referring to the composition of the average crustal rocks (thanks for pointing that out that ambiguity, I'll be more precise in future versions of this video). The bulk ("whole") composition of Earth is a bit harder to figure out because we need to make some assumptions from meteorites, seismic waves, and geochemical models. Here's a good paper on our current thinking on bulk Earth composition. quake.mit.edu/hilstgroup/CoreMantle/EarthCompo.pdf

Hi, Do Geologists sometimes need the services of a Geochemist to properly identify the Rock or Mineral Sample that has been found? FOR INSTANCE:: Let's say that there are two Minerals with each looking very similar in their physical appearance and each having the same 3 Chemical Elements that make up each Mineral but in different proportions by Percentages (%}. One Mineral Sample may have the Percentage Ratios of 60-20-20 and the other may have the Percentages of 40-30-30, again with the same Chemical Elements in different proportions. I would "assume," if I may,, with that much variation in the Percentages of the Elements, there would "most likely" be enough Physical Appearance variations to properly identify the two Mineral Samples by sight by the Geologist. If they could NOT be readily identified by the Geologist, would that require the Samples to be Examined & Analyzed by by a Geochemist? ~TIA, Bruce~

@EarthandSpaceSciencesX

Good question. Geologists, for the very reasons you just cited, receive extensive geochemistry training during their undergraduate years so that, in a sense, they can be their own geochemist when needed. A common example of what you are bringing up is plagioclase, being a solid-solution, can have very different chemistries depending on the condition which formed the mineral. Geologists learn how to easily measure the chemical composition of plagioclase during their sophomore or junior years using an optical microscope. Same for most of the other common rock-forming minerals.

I am guessing the relative abundance of elements in the earth is with respect to mass rather than relative number of moles. Mass vs. moles would give different ratios of elements. The relative abundance of hydrogen, sodium and carbon, in number of atoms, is going to be much higher than their contribution to total mass because they are light elements.
