[edit] Litchfieldite

Hey there, Zimbres. I noticed you added Litchfieldite to the list of rocks. We are trying to keep the list, especially for igneous rocks, to modern nomenclature, for instance the IUGS standard. Look for a good site on this attached to the Lamprophyre page in the "see also" section. To me, Litchfieldite is not a true rock type, but a name derived from a type locality. It is also not really a true igneous rock type, because all the examples are metamorphosed nepheline syenites.

It would, to my mind, be better to move Litchfieldite into the main article on nepheline syenites, unless there is some particular petrogenetic difference bwetween the two (aside from metamorphism, which at this time, seems the only distinguishing feature between nepheline syenite and litchfieldite).

I also note that a lot of the example localities are brazilian, and so are you, which is good; we always need more rocks and regions described. However, you could probably move the individual occurrences to their own pages, or (preferrably) under an umbrella page of the South American alkaline province or similar. Try to keep type examples out of the page which describes the rock.

_________________________________________________________________________________________________________

Hi, Rolinator, thanks for your suggestions. I've note that my English was also corrected and I would thanks the good soul who made that. For these days I'll be buzy but soon as possible I`ll work on this article in the way you proposed. About the classification of litchfieldites as "igneous rocks" I desagree, because for me and for a lot of brazilian researchers, the metamorphism has impressed some characteristics that is unique to these rocks, as, for exemple,the subsolvus paragenesis of pure albite and microcline; and so on. Anyway, I think it is a matter for controversy and I would like to reach a point of convergency with you and others non brazilian geologist, about the best way to put these facts in an ecyclopedic space. Think lietchfieldite as an orthogneiss, like some granitic ones.

I think Wikipedia is a grateful challenge for us to speak beyond the academic circle.

By all means fix this image! I'll send the files if you work in Adobe Illustrator.
