Continental arc

(

)

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

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)

Issue 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)

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)
