Identifying Transgressions and Regressions in Rock Sequences

In this tutorial, Jennifer talks about Walther's law and how marine transgressions and regressions can be identified in a vertical sedimentary rock section.

Thank you so much,u r the only one that I got the idea from her because your explanation is straightforward

[@edward05lan]

Thank you very much Jennifer Lewis for explanation remains me again

[@keiththomson7593]

Needed a quick refresher before my final today and I appreciate it!

[@joeybashaw7104]

Thanks Jennifer, I was looking up regressive rock music and I stumbled about this and now know more then ever

[@EarthExplained]

:) Awesome!

Thank you for this video! Just subscribed and need to thumbs up!

[@nadavnavon2140]

Great explenation, thank you so much!
Challenging to distinguish a marine transgression with a bouma sequence.

Thanks Jennifer. The lectures I attended at uni are work-shop based, which I like. But your video has allowed me to revisit the introduction of the lecture ideas as I get my head around it.

Thank you so much for this!!!!!!!!!!!!!!!!!

You're so welcome!

Thank you so much for this video Sedimentology is so challenging

[@mohammedsadi7784]

Good work, we need to explain the sequence stratigrapy

[@Aitch9000]

Your video is really helpful

[@StereoSpace]

Interesting. I'd never thought of that but it makes complete sense. Thank you.

[@amgaa735]

Great work. This explanation is easy to understand. Thank you.

[@LuciferMorningstar-xd8tn]

Thanks a lot! Very vividly explained❤

[@TheEarthycrunchy]

I love your videos

Beautiful explanation !

[@muhammadfahim3736]

Very well explained in a simple way.

Great , alot of respect for you dear lady.

[@pranavsprem]

Your explanations are excellent mam! Really enjoyed the lecture

[@ElCapitainMuchos]

Absolutely Brilliant ,Excellent explanation, thank you

[@EdwinPranataSiahaan]

I think there must be subaerial unconformity right above the first Sandstone since the sea level fall and it is hard to say that the sandstone still deposited above the other Sandstone beside Channel Sand CMIIW.
Overall you do great.. Keep it Rock

Very well explained.Thanks

[@dilisansunthareswaran9770]

Great explanation!!!

[@bapaktimin7665]

Basically walther law is regresion or trangression, progradation or reteogradation. What lecturer is wrong they tell student that the vertical section is deposited at the same time line or horizontal conformitiy. Actually the deposit below and abobe is from diferent strata or different age record altough the difference of the age is not geologically significant because usually it is at the scale of parasequence. So it records facies change vertically not facies deposited at same time horizontally then in the rock record we see them vertically. The strata deposited at the same time correlate somewhere laterally from where the position of the profile.

[@sauravgogoi4535]

Mam.. can you help me out with the names of sedimentary structures which are used for determining top and bottom of beds.?

[@ulviss]

This is very helpful ))) but I have seen one article in textbook which explains type of regressions and second type of regression is misunderstanding for me. This is it: "If the mass of sediment supplied to an area requires more energy for its dispersal than is available, baselevel rises and sediment accumulates commensurately" Can you explain me? )

[@leecadoo3294]

I'm not sure. because we say the uplift of a plate(continental) cause the first type of regression, the sea level relatively drop down, but the deposit tempo not change; or we say there is no tectonic movement but the tempo changed, become faster, before the fine clast should be gone far to deeper place and deposit they just in a closer place deposit and compact and diagenesis, so we say base-level rises.

[@whatabouttheearth]

It's stated odd, but I think it's saying that if the energy isn't enough for dispersal of a certain size of sediment than whatever sediments that accumulate will be small enough for that level of energy (commensurate: corresponding in size amount or degree).
If there ain't enough energy to move sediments of a certain size than that size ain't getting moved.
But like I said, that is worded odd.

[@kreytonumeres5895]

Dear Jennifer could you present explanation about carbonates please I would like to put a video explain the formation an the recognition y a seismic line. Best regards

[@mikelooby8362]

Thanks from gulf.

[@Poppageno]

Great Jennifer! How can I apply this to a sandstone formation tilted on it's side? Which side was "UP"? to know if it transed or regressed.
