Classification of Sedimentary Rocks Part 1: Terrigenous/Siliciclastic Rocks

We now know what sedimentary rocks are, but how do we classify them? We have to discuss three broad categories of sedimentary rock, and the first of these are terrigenous or siliciclastic rocks. These are rocks composed of clasts, or fragments of silicate minerals, derived from the erosion of preexisting rocks. Further categorization can get pretty tricky, requiring interesting looking ternary diagrams, so let's get a closer look now!

Geology is one of the fields where you can lick the science

The term "quartzwacke" has to be one of the most wonderful words I've ever learned. I'm going to try using it in casual conversation to see if the person I'm talking to gets offended or not.

[@tonydagostino6158]

You'll definitely be the only one. In a geological career of over 44 years the only time I've used the term might have been on an exam. Too bad it's too long for Scrabble

I love how the fields of science overlap and support eachother. 🎉

For as great as your content is damm you are underrated. Sure you have 2.45 million subscribers, but for what content you produce, thats really a shame, i mean you explain this stuff better then most schools can.

[@adhitripras8945]

Very good explanation ❤

I'm taking Sedimentology and Stratigraphy this semester. Our sandstone ternary diagram was a bit different. I wonder if it's because our book is old. There were quartzarenite, litharenite, arkose, subarkose, sublitharenite, feldspathic litharentie, and lithic arkose. And the percentage of matrix mud was 0-15% arenite, 15-75% wacke/graywacke, 75-100% mudstone. Anyways, it's cool you are covering some geology!

[@mckennachristine7206]

my sed/strat prof said that there are many different sandstone classification systems, which will differ from textbook/classes. Just use whichever is given!

[@EvTheFlickFan]

Hey, I have a question about something you mentioned in another video but cannot find. I remember you stating in a debunk video that “you can’t find the study on [ insert website ], so it’s not real science.” The website in question I believe was like a search engine in that it could look up scientific studies.

Thanks, Dave. Love the geo stuff.

Do you have a video on volcanic hydrothermal intrusions or better yet the geology of gold?

Frank Turek did a collab with the duck dynasty guys recently, where they “dunk on” the Big Bang, if you want to give that a look….and yourself a migraine.

[@franekkowalski9978]

Dave pleaaase do yhe engineering course you promised years ago😭😭. We are all in need!! (espacially needed is the topic of signals and dynamics systems)

[@hardrocklobsterroll395]

[@s.9417]

Can you please talk about writing a theoretical and actual yield when writing organic reactions notebook. This is vital in organic lab yet I do not see videos about it.

[@bugsbunny852]

If you did a series on higher level maths like linear algebra, differential equations, functional analysis and series on some engineering courses like thermodynamics, EM, classical mechanics and quantum mechanics that would be awesome. It seems like you have the foundational knowledge to excel in those subjects and teach others.

[@ProfessorDaveExplains]

I did an extensive linear algebra series, and have done some stuff on E&M and QM as well.

what is the difference between human DNA and Rock DNA

[@ProfessorDaveExplains]

Hopefully you are joking, but in the chance that you're not, rocks don't have DNA.

[@pauly51]

How about concretion or breccia? How do you tell the difference?
