Lacustrine (Lake) Depositional Environments & Stratigraphy | GEO GIRL

[@suntaekbang1180]

Thank you for your great explanation. It helps a lot to understand lacustrine deposit.

[@JBond-zf4dj]

Love your videos! They cover everything I'm taking in Geology this year, and are laid out much better than how we're being taught in class.

[@GEOGIRL]

So glad you find them helpful! Let me know if you ever have any topic requests! ;D

[@geoscilove6609]

Really informative. Grateful that your channel exists on YT :)

[@GEOGIRL]

Thank you so much, this made my day! ;D

[@whatever3692]

Thanks for providing this material as it was not available anywhere else on youtube

[@GEOGIRL]

Thank YOU! That is my entire goal, to fill the Geoscience gap on YT. So to hear from you that you think I am doing that means a lot, thanks for the comment! ;)

[@adampax]

Thanks for another informative video! I get a bit confused by the definition of overfilled and underfilled lakes. Surely all lakes ultimately have to be balanced (averaged over a sufficient time window), because if there is more input than output then the lake volume would grow indefinitely, while if there was more output than input, then the lake would eventually disappear. Am I missing something in the definition?

[@GEOGIRL]

No you got it, this is actually what happens! In underfilled lakes the lake typically eventually disappears (unless there is a change in its balance), this leads to the formation of salt flats or 'playa lakes' essentially dried up lakes. The opposite for overfilled lakes, they just continue to slow grow and increase their output in runoff :)

[@adampax]

Ah I see. Very clear, thank-you! ❤

[@nitrowilly82]

This was a great 20 minute review of 8 credit hours of my degree. Holy fuck did you summarize Fluvial Deposition at Lakes well. I salute you! 07!

[@oliverweeweepie3132]

This lake video is amazingly informative ❤️

[@GEOGIRL]

Thank you, I worked very hard on this one, so I am glad that comes across!

[@orbaycam4746]

Is there any generalized columnar section for lake depositional environments?

[@palandasghodeswar6169]

Thanks for giving very important information about Hydrocarbon ,coal in Lacustrine environment . Is there Phosphates pockets in and around this type environment ,madam ?

[@GEOGIRL]

Phosphate pockets? I am sorry but I have no idea haha. If 'pockets' is just referring to deposits, I am sure nutrient rich (eutrophic) lakes have plenty of phosphate deposits (although, if there is a lot of primary productivity, they may use most of the phosphate up before it can become deposited). I hope that helps :)

[@geoscilove6609]

Is there any video where you explain about progradation etc?

[@moosamoosa8214]

i couldn't find the image of Open vs. closed lakes

[@moosamoosa8214]

can you please sand it to me I need it for my presentation):

[@GEOGIRL]

Unfortunately, that's not an image I found online, it's a figure I scanned form the facies models 4 book: amzn.to/3pdsAPY. The closest I could find online is: gsw.silverchair-cdn.com/gsw/Content_public/Journal/geosphere/12/3/10.1130_GES01143.1/3/721f1.jpeg?Expires=2147483647&Signature=p5iJJJoA5ddP3gmUZpRxtEq9CHuiWpw7IR-e5A~cVKVx7TqkhVl5VZw9vuMm2EJ3XsSlWzQyI6kp71-lYnbO8fTrBnavvobdoGDXnkzEF~goSZdtUJ2CNbz5toC2daa7F0zk63JOt2uioBj3VNu3ZWjaVYT37Lp1ymiCCmL1NZR6lsFOW1Uf~8PgZDYGoHdtI~4-pb~fJh7WzdW9IWykzJEASm186PlyBUvrtfGeDtb8U5PGs-POrhZ9O5oTwkCD7cyPu-5QWfNQwsKUXKhrsfPWzCdbhsN3LPMEk-CGOolMwgD-QBKwoMKmfikBtPBsYDiDlKjQ4RfkJVBNR3rxLA__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA. Hope that helps!

[@moosamoosa8214]

@@GEOGIRL Thx (:

[@CMDROldDuck]

Where I live there are also beaver-made lakes, though geologically speaking I guess they’d be classified as ponds ( just don’t tell the locals that, lol).

[@oladimejioreoluwa6507]

This is a nice explanation, I’m in your DM girl

[@vaibhav3796]

Focus is totally on the top right corner 😂 admiring the beauty wherever you see it

[@buithach4084]

Polymictics is not just a lacustrine phase. My gf went through the same thing now she's my ex.
