I created the following table. I hope it can help someone out.
Anyone have any ideas of how I could improve the chart?
Any ideas where I could post this where others might benefit from it?

Spent the last few hours improving it a bit

@Granpa,
you should further brEAk itdonw to include the solid solution series of the plagioclases and then consider the textures and maybe which of the rocks may be anatektic
BTW, THIS Is ALREADY AVAILABLE TO STUDENTS OF GEOLOGY AND COLLECTORS OF MINERALS MAYBE WOULD MISS THE POINT THAT YOURE ACTUALLY SHOWING US THE MINERAL ASSEMBLAGES , in igneous rocks PRIMARILY.

Glad ta see ya, Im soon checking out of this place so itd be good to have another folk serious about igneous rocks.

@Granpa,
we can simplify that entire chart by considering other elements (for example rather than presenting rhyolite, andesite, and basalt in parentheses, make another to include QLL the effusives. Also let conswider the rocks where free quartz no longer occurs. I unerstabd where your chart is going but I think were making it too cpmplicated because having all these rocks associated with one genesis, we may have to consider some (like granite , alaskite or even peridotites or serpentinite) ,often as metamorphic assemblages. Consider biotite granites . Id look at a QAPF diagram and consider its genesis

@farmerman,
I see what you mean now about metamorphic rock. I will have to think about it some more.

@Granpa,
too much infoormtion . What I meant was to incorporate "anatktic" igneous rocks. Biotite granites ere probably metamorphic. I ouldnt include the sedimentary rocks becauae natexis of hale is often a metagranite or diorite.

I think e need to simplify it much more(Id only consider )
1silicate and free silica content (% free silca v silicates)
2Felspar solid solutions (Go from K to Ca spars)
3 feldspathoids v metalloids
4 effusives or plutonic (texture)

trying to make it more complex will have us getting caught up in the several areas of "exceptions". (like remelts of peridotites nd serpentinites) or even kimberlites (species of garnets therein-(Pyr-al- sp-ite/Uv-gr-and-ite)

Are you doing this for a summer school project?

@farmerman,
Just saw your reply. A lot to think about.
In the meantime I added moon rocks.

@Granpa,
ya lot me in that lst one. Wheres the connective tissue among the various rock types???

@farmerman,
MY humble opinion, you should restrt nd try a more simple approach that would actually be more genesis oriented. Like , across the x axis have the actul amount of free silica, y xis from the top, hve the feldspar/feldspathoids (melanocrats would "fall out". THEN, for each x/y group, split that into plutonic v effusives (Stuff like alaskites nd porphyrys would plop out)

THIW WOULD, of course, only be for igneous rocks.
The same can be done for metamorphics except they would be discussed bse upon (Chlorite to kyqnite/ sillimnite gradation) as well as presence of specific garnets.

BTW, such charts have been available for many years. I think you are trying too hard to make a "Mineralogical theory of everything", no?
