Possible plagarism[edit]

The body of the article appears to be plagiarized from "Petrology: Igneous, Sedimentary and Metamorphic" by Harvey Blatt, ISBN 9780716737438. I have included the Google Books link to the e-Study guide for the book as proof. If somebody else can confirm this and fashion a suitable paragraph or two, we can get this page looking real nice.,+dark-coloured,+volcanic+rock+characterized+by+phenocrysts+of+olivine,+titanium-rich+augite,+plagioclase+feldspar+and+iron+oxides&source=bl&ots=pOY9IB-RmJ&sig=6d9geaFbbrcXbxKSQ8SycVBPFdM&hl=en&sa=X&ved=0ahUKEwj2so-M0qrJAhXHWD4KHV1wCsUQ6AEIMzAE#v=onepage&q=is%20a%20fine-grained%2C%20dark-coloured%2C%20volcanic%20rock%20characterized%20by%20phenocrysts%20of%20olivine%2C%20titanium-rich%20augite%2C%20plagioclase%20feldspar%20and%20iron%20oxides&f=false

I don't have a copy of Blatt et al.'s textbook but unless someone else can quote the possibly plagarized text from the textbook itself, I doubt that Wikipedia has plagarized this textbook in this Alkali Basalt article because:
I think the study guide has plagarized Wikipedia. I think that most, perhaps all, of the definitions in the study guide (published in 2014) for Blatt et al.'s geology textbook (3 editions published before 2007) appear to be plagarized from current or old versions of Wikipedia articles. I've also spot-checked some examples of this "publisher"'s series of study guides for a whole range of other geological and non-geological textbooks. These other guides also appear to include plagarized text of past and present versions of Wikipedia articles. Old versions of Wikipedia articles, edited before 2015, seem to give a particularly close match to the content of the study guides that I've checked. On the balance of probabilities, I think that it's too much of a coincidence that so much of the text in this set of study guides, for many textbooks on a wide range of subjects, can also be found as text added to Wikipedia articles by many unrelated Wikipedia editors, who often cited sources other than the textbooks referred to in the study guides' titles. I think this increases the probability that the study guide text came from Wikipedia, not from the textbooks. GeoWriter (talk) 00:05, 26 November 2015 (UTC)
