Talk:Lithosphere–asthenosphere boundary

I think it looks good. I only have one suggestion that it may be helpful to add a picture of continental and oceanic LAB deference, which is already mentioned by JKidd93 though. Tomoyuki6 (talk) 23:40, 27 April 2015 (UTC)

@Tomoyuki6: Thanks! I tried to show some difference between them in my current diagram, though I agree it isn't detailed or as clear. I'll work on getting another diagram up soon. Thanks for the suggestion! NealeyS (talk) 14:05, 1 May 2015 (UTC)

You could also go into possible rock compositions given different depths and such. Like the other have already stated, pictures could be fun. Losgrinch30 (talk) 22:01, 19 April 2015 (UTC)

@Losgrinch30: The composition doesn't really differ much chemically between lithosphere and asthensphere aside from one being more depleted than the other but I will try to discuss that in further detail in the article. Thanks for the feedback!

I agree with JKidd93. The article is really coming along well, but I diagram showing locations in the mantle would be a good visual for people viewing the page. You could emphasize the changes in depth of the LAB due to varying factors (age, temperature, location, density, etc.) in the diagram. Mhunter2 (talk) 11:48, 14 April 2015 (UTC)

@Mhunter2: I finally go a pic up! I do agree a diagram emphasizing the changes in depth of the LAB due to varying factors (age, temperature, location, density, etc.) would be very useful, I will try to work on that. Thank you for the suggestion!.

I think the page is a good start. A diagram with the Earth's mechanical layers (at least the upper mantle) would be a good idea to include to show the location of the LAB. You could also point out differences between the continental and oceanic LAB in the diagram. Jkidd93 (talk) 20:13, 4 April 2015 (UTC)

@Jkidd93: I definitely agree about the diagram-- still working on that. I should have a couple illustrations up soon. Thanks very much for the feedback! NealeyS (talk) 15:24, 6 April 2015 (UTC)

Like the article thus far. My only qualm is the first sentence under "Defining the LAB", where it says "Boundaries can be studied using seismic waves". In the training it was stressed that Wiki articles should read like an encyclopedia. I feel like this sentence would be very at home in a research paper on the Lithosphere-Asthenosphere boundary, but for this article I might reword it like this....Mcooper3 (talk) 03:55, 5 April 2015 (UTC)

"The LAB boundary has been extensively studied utilizing the process of seismic topography. Wave speeds differ between the rigid lithosphere and ductile asthenosphere due to the differing physical properties of each layer, allowing geophysicists to measure waves being either reflected off or transmitted through the boundary." — Preceding unsigned comment added by Mcooper3 (talk • contribs) 04:05, 5 April 2015 (UTC)

@Mcooper3: Thank you very much for the suggestion! I completely agree that the sentence needs work and I like your replacement-- might just go with it. :) I will actually be expanding that paragraph quite a bit, focusing more on the use of seismic waves to study the boundary. I mostly just wanted my working draft up already, sans edits apparently. haha So many articles yet to read! NealeyS (talk) 15:24, 6 April 2015 (UTC)

@NealeyS: i would add the different ways we define the LAB: Seismological LAB, mechanical LAB, thermal LAB, etc… 204.29.102.55 (talk) 18:12, 13 April 2015 (UTC)

Receiver functions have been important in studying and defining the LAB.Mmdriskell (talk) 18:34, 5 May 2015 (UTC)

Short name

If it is referred to by physicists as LAB, it would be useful to know how they pronounce it - is it 'lab' to rhyme with 'dab' or is it perhaps 'ell-ay-bee'? For comparison, the Old Red Sandstone is commonly referred to as the ORS by geologists; they say 'owe-ar-ess and not 'orse'. thanks Geopersona (talk) 06:51, 8 June 2018 (UTC)

The name looks awkward. It should either be "lithosphere-asthenosphere boundary" (all small letters) or "Lithosphere-Asthenosphere Boundary" (all caps). References 1, 8 and 9 use the second option, which I think is the best choice, as it is a definite term (and abbreviated LAB), references 10 and 11 use the lower case version. The current name does not look good. Tisquesusa (talk) 17:31, 30 August 2018 (UTC)

I would support renaming it to Lithosphere–asthenosphere boundary, based on a quick review of the first 100 relevant papers listed by Scholar [1]. Mikenorton (talk) 21:07, 30 August 2018 (UTC)

Overhaul

Hi! I've performed a bit of an overhaul on this page. This is part of the Stanford University course "Journey to the Center of the Earth" taught by Professors Simon Klemperer and Wendy Mao. Sections have been added to address the different ways the LAB (for the question on pronunciation it is "ell ay bee" [unsure how to add a pronunciation guide to the article]) is defined.

Irina Artemieva was gracious enough to provide the main graphic for this article (schematic of definitions).

The "seismic LAB" has been added to the new "Measuring the LAB Depth" section due to it being more of an observational definition than a mechanistic definition.

Hopefully with the new organization and information added this page will be more likely to grow in the future. Arblanchette (talk) 21:44, 18 March 2019 (UTC)
