Continental arc

• ( Back to T:TDYK
• Article history )

• ... that continental arc volcanoes have magma formed from a mixture of melted asthenosphere and crustal rocks?

• Reviewed: Battle of Besançon (first half)

Moved to mainspace by MichaelZuo (talk). Nominated by Graeme Bartlett (talk) at 09:22, 17 November 2014 (UTC).

• 16px Long enough, fresh enough when nominated (2d after move from draft space). No dispute templates, no BLP issues. Citations checked where possible (many academic journals accepted AGF). Issues found: 1) Hook exists in article at Continental arc#Magmatism but I can't find nearby citation for this. 2) Also can't verify the Cascade arc statement on the missing trench; suggest this if you need it: Deep-Sea Trench (Not!)

• I got the hook statement from the previous section Continental arc#Petrogenesis. This is referenced by number 4 the book titled "An Introduction to Igneous and Metamorphic Petrology" which you can read here: the page number is 211, right column. (That should address query 1) I will nowlookat query 2. Graeme Bartlett (talk) 01:50, 29 December 2014 (UTC)

Sorry I don't see the word "asthenosphere" in that section and my limited knowledge of plate tectonics/geology doesn't allow me to make a full determination. We need someone with expertise in this subject to look at it. — Brianhe (talk) 02:05, 29 December 2014 (UTC)

I have used your reference for the Cascade Arc now to address query 2. The figure 3 shows what is happening in a comprehensible way. Graeme Bartlett (talk) 04:20, 29 December 2014 (UTC)

Issue 2 looks good. Like I said before, I can't resolve issue #1, it will need somebody with more knowledge of geology. Also I have noted a new issue #3, below. - Brianhe (talk) 05:29, 29 December 2014 (UTC)

• 16pxIssue 3: Upload annotation on File:Andes_Continental_Arc.jpg says it was "adapted" from a screen shot of Google Earth. The underlying graphic would be copyrighted by Google, I'm pretty sure this not allowed. — Brianhe (talk) 05:28, 29 December 2014 (UTC)

• Issue3 sorted out by removing the image fromthe article. Graeme Bartlett (talk) 04:55, 5 January 2015 (UTC)

16px I'm going ahead and OKing this as-is now. I asked a sometimes collaborator who knows geology better than I do, to also have a look at the article if/when possible. — Brianhe (talk) 05:00, 5 January 2015 (UTC)
