This article was the subject of an educational assignment in Fall 2014. Further details were available on the "Education Program:Louisiana State University/GEOL 4066 Plate Tectonics (Fall 2014)" page, which is now unavailable on the wiki.

A fact from Lwandle Plate appeared on Wikipedia's Main Page in the Did you know column on 20 November 2014 (check views). The text of the entry was as follows:

Did you know... that the Somali tectonic plate is breaking into tectonic micro-plates, like the newly-formed Lwandle Plate?

A record of the entry may be seen at Wikipedia:Recent additions/2014/November. The nomination discussion and review may be seen at Template:Did you know nominations/Lwandle Plate.

Comments from Graeme Bartlett

I would like you to expand on the meaning of "plate circuit closure". Does it even require a Wikipedia article (or on plate circuit?
In the Boundary types section, mention the other plates the boundary is against. Mostly the types are not mentioned, but if nothing is known that is fair enough. Perhaps the whole thing is a phantom plate.
Also describe the location of the plate relative to Africa and Madagascar.
Avoid using "we". see WP:WE for more on this.
On your diagram can you label the Southwest Indian Ridge, and the African rift system?
How does GPS data work for plates that are under the ocean surface?
The see also section is likely redundant as all those links are in the article anyway. Read WP:see also.

For plate circuit closure, one explanatory sentence will do. You should be writing for the high school student, so that should give an idea how much needs to be explained. You can write a whole page on the topic if you wish, but you are the volunteer!
For feedback to my comments, here is the best place, as they are about the page associated with the talk! Then also we can see all the conversation at once.
Thanks for taking on my suggestions, I will take another look at the draft. Graeme Bartlett (talk) 23:10, 26 October 2014 (UTC)[reply]

More comments

Thanks for taking on most of my suggestions above
You say "the only plate boundary with part of the boundary on continental crust" but isn't the boundary between India and Eurasian plate on continental crust (and ocean floor too)?
Is there any information about the sea floor on the plate, eg thickness, sediment depth and nature, magnetic anomalies, extinct spreading ridges, age?
Minor: References come after the punctuation, eg after the ".".

Comments from Austin

Great article as it was an easy and informative read.

First section: The mention of its velocity in the second sentence disrupts the flow a bit. Here you have: Location-velocity-location-crust type-location. try reorganizing the sentence to flow as location-location(as it implies crust type)-new discovery/velocity. This will then lead into you Origin section better.

Figure caption can describe / walk through what is being shown in the figures a bit more. In the third figure, a legend should be added even though it is the same. Plus as you mention earthquake data is commensurate with the gps data and plate movement, you could plot EQ data here as well.

If any later expansion, could look for field mapping investigations and studies on the rock record of madagascar which support the different models. Ajamesm28 (talk) 00:31, 16 November 2014 (UTC)[reply]

Comments and suggestions from Chang

The topic is interesting and the text part is easy and clear.
Based on the last figure, what do you think the plate will be like in the future? for example its topography, thickness of lithosphere.
Besides the map view, I think you should maybe try to expand more about Lwandle plate, I mean if there are more new data about this.
- It would be good to put some GPS data and figure showing the movement.
- If there are some petrological data and geochronology in the triple junction area and area near Lwandle plate, it will be make the argument stronger.
- Is there any seismic profile or cross section showing the lithosphere and crust in this area, if there is, I suggested to put them on. It would also be good have some known cross section in the nearby area, like Somali plate and Nubian plate.

Feedback from David

Since there isn't a Wikipedia page for microplates, you could link to an outside page, like "http://geology.about.com/od/platetectonics/g/About-Microplates.htm," that could help! A citation would be helpful for the sentence "By including the Lwandlean Plate in their calculation, researchers were able to more accurately solve for the intersection between the East African Rift and the Southwest Indian Ridge." You might define "mathematical plate circuit closure." I like your final sentence in the Origin section, about the applications of the plate to modern tectonics. A separate section about the geology of the area may be a good idea, like a general geological background, like you would have in a paper, and maybe one of the map figures on the page could go with that.
I would perhaps make the world map figures thumbnails, they seem somewhat intrusive.
The sentences "The majority of Lwandle's plate boundaries are not well understood. What is known is:" sound strange to me. Maybe something like "The Lwandle plate's boundaries are not well understood, but several specific characteristics of each have been identified." and then go on to detail them from there.
The figure at the bottom of the page is strange, maybe make it a thumbnail and put it on the left or right side of the text? Your references look a little strange compared to other Wikipedia pages I've seen, but I do appreciate that it looks like the references section of a paper. Overall, this is a good article on an interesting subject, well done! — Preceding unsigned comment added by Chang21liu (talk • contribs)

Comments from Murfas

In the second paragraph is says "resting off the southwest coast of Africa". Shouldn't this read the "southeast coast of Africa"? — Preceding unsigned comment added by Murfas (talk • contribs)

Sorry, my bad. Fixed now. -- intgr [talk] 20:39, 20 November 2014 (UTC)[reply]

SVG images

@Mmorr42: As we talked on IRC some time ago, can you please upload SVG versions of the images? It's preferred by the policies (WP:IUP#FORMAT) because it has the advantage that other people can modify the images later if needed. I see that you already uploaded File:Updated lwandle4.svg and the fonts don't render correctly -- that's fine, it can be fixed up by the next editor who wants to modify it. -- intgr [talk] 08:37, 20 December 2014 (UTC)[reply]

@Intgr:User:Intgr, is this better? And just to verify, it's totally fine that the fonts are all wacky as of right now? I've received my grade for the course already, so I have no problem keeping these SVG images on my page now, despite the font problem. Mmorr42 (talk) 19:54, 22 December 2014 (UTC)[reply]

Oh, I meant that you should just upload the images, not use them in the article yet. But I linked together the SVG and raster images and reverted the article, so it's all fine. Thanks! -- intgr [talk] 12:00, 23 December 2014 (UTC)[reply]
