Ripple Cross Lamination

[@lazywagon]

Hello, I am from India and I'm studying Geology. Your videos are so helpful for my Sedimentology and Stratigraphy classes. Thank you!

[@CaNQan]

I don't know you But I would like to thank you. These lectures really can be helpful for all geology students around the world. I'm a MSc student from Turkey.

finally understand the formation of cross stratification. Geology without visualization/demonstration is nothing.

hats off for this generous work ... greetings from INDIA (land of himlaya)

Ur vedios r indeed benefiting!! Thank you so much

[@dfan]

thanks, very helpful. I have a geo exam in an hour! lol

What is the volume of the sedimentary rock layers around the world?

[@siddharthranjan8013]

Almost 5% crustal volume

[@JungleJargon]

@@siddharthranjan8013 What is the volume? It’s more like 3%. What is that volume?

[@atari88748]

Helpful video, I understand xstrata a little better now. If you had a camera person however, please fire them :D

[@gucoguco]

a realy appreciate your videos. you should retake the project. greeting thanks from universidade de brasilia

How is biogenic secondary sedimentary structures indicative of the depositional condition?

[@sumnerd]

It depends on the type of biogenic structure. Often they form when the sediment surface is stable, in other words, the sand is no longer moving. That allows organisms to burrow the sand or microbial mats to grow on the ripple surfaces. Some biogenic structures, such as footprints, can form as the sand is moving, but they tend not to get preserved.

Thank you soo much.... :-) full of gratitude. i would love to keep connected to you.

Wait! I just watched a crazy guy jumping up and down in a swimming pool and now I am here?

[@r.f.j.arthur3189]

You can show the erosion and transport by rubbing out some of the chalk lines and drawing new lines to show the accumulation but the profile need to be correct AND be consistent. You really need to keep the direction of time progressing slowly and in one direction to reflect how how the ripple/dune migrates, and not confuse matters. 5 out of 10
