Hummocky and Swaley Cross Stratification in outcrop

IMPORTANT: Science never stands still and our understanding of natural depositional systems is constantly under revision. In the video, I mentioned that HCS and SCS indicate deposition on the shelf and that is no longer true. For years sedimentologists were reluctant to call the bedforms of combined flow by turbidity currents Hummocks and Swales and had to come up with terms like "plow-and-fill" to avoid critique by the community. Until 5 years ago "pseudo-hummocks" were gaining greater acceptance. Now we have the freedom to call these deepwater sedimentary structures Hummocks and Swales.
Also, most sedimentologists have chosen to drop the idea of a Middle Shoreface - therefore in this video most of the succession you see which has stacked HCS and SCS would be part of a lower shoreface that is storm-influenced.

Nice video! What such beautiful structures!

Very helpful, thank you for this amazing informational video. I learnt a lot from this and it has made me realise exactly what a hummock and swale look like. It really is an amazing example of hummocky and swaley cross-stratification.
- Lots of thanks from a Camborne School of Mines (CSM) geologist over at Cornwall, England. :)

It is a very concise and interesting lecture on Hummocky and Swaley Cross Stratification. I liked it very much. You are one of the best Sequence Stratigrapher Ali Jaffri :)

[@johannsidial6423]

excellent vid, helped me lots in my outcrop interpretation

[@alaaazzam4041]

It will be great to meet you or work with you one day !!! I am sure it will be a great experience. I am following you everywhere and you are really a great geologist !!! You inspire me a lot 😊👍

[@appliedstratigraphix6844]

Thank you! I appreciate the kind words.

In every layer of the earth we find sediment from an alien dust cloud. Also in the youngest layer, which is less than 6000 years old, we find sediment that is perhaps more than a billion years old. This dust cloud originates from the collision of our planet with another planet, planet 9. That planet crosses the ecliptic plane of the other planets every few thousand years. Just before the beginning of our era, that planet was seen, depicted on coins and remnants of that dust cloud were found in the ice sheet of Greenland.

Nice and educational

+Mark Ma Thank you! we're glad you liked it.

[@joaocalandrini2330]

so cool great vídeo i wanna ser many lik this

[@appliedstratigraphix6844]

+Joao Vicente Thank you so much Joao. We will be heading into the field again next week and will create a few more and upload them. Have you seen the rest on our channel?

[@ahmadmanzoor6067]

Indeed impressive video...
Helped me lot, it take me zero seconds to press the bell icon after seeing the stuff oll.
Can you plz share your mail because I am the geology student want to reciprocate the things with such geologist, I hope you will acquiesce submission.
Thanking you,
With regards Ahmad Manzoor Dept. Of Geology University Kashmir

[@rohitgupta2363]

I want to know details about flaser bedding, massive bedding, convolute bedding..
plz make me understand these sedimentary structures as same as u make us understand these humocky rock stratification

[@Jackie.millan]

what is the mudstone fraction in this outcrop?

[@appliedstratigraphix6844]

Jackie I didn't measure a section at that location so I cant give you an exact percentage but its incredibly low because it seems to be a storm-dominated shoreface with amalgamated tempestites. Ambient condition bioturbated mudstones seem to have been eroded away for the most part. If you're in Colorado or New Mexico Id be happy to give you the exact location so you can go check it out.

094247005 you know it 😂

[@Jackie.millan]

Ali Jaffri thank you.. i just needed to know for my geology lab report

[@geoffgeoff143]

What sort of depth?

[@appliedstratigraphix6844]

Geoff depths will vary depending on the gradient of the shelf and the fetch in front of the coastline. In the Western Interior Cretaceous Seaway of North America its 10 m for FWWB and 40 m for SWB.

Geologists only talk and think in millions of years. They have different methods for determining the age of rock layers. However, there is one small problem. Ancient books tell us that a cycle of natural disasters threatens the earth and all living things. The cause of this cycle of disasters is a ninth planet in our solar system orbiting the sun in an eccentric orbit. Features of the natural disaster include a massive tidal wave, higher than the highest mountain, flooding, storms, rain, volcanic eruptions, earthquakes, and a fiery asteroid bombardment. That planet is surrounded by a gigantic twisting cloud of dust and meteorites. That cloud obscures the atmosphere, pollutes the water and covers the whole planet Earth with that dust. At the end of the crossing of this planet 9, the earth is covered with a horizontal layer of wet mud, a mixture of sand, clay, lime, fossils of sea and land animals, shells and the deposit of that dust cloud and asteroids. So every layer on our planet contains material with the same antiquity, perhaps many millions of years old: the deposit of extraterrestrial clay. If you don't know about this cycle, you have no idea how our history has evolved. To learn much more about planet 9, 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
