RockSuiteCom:
The rocks contain (a) modal foids and /or alkali amphiboles or pyroxenes (b) normative foids or acmite


RockSuiteCom:
, Basic to acid igneous rocks containing groundmass augite, hypersthene, (basalt and andesites) or hornblende or biotite (dacite, rhyolite), little or no iron enrichment on an AMF diagram.


RockSuiteCom:
Alpine-type peridotites gabbro dolerite, spilites keratophyres Defines basic to ultrabasic rocks representing the ocean crust. Hartzburgite dunite lherzolite wherlite pyroxenite leuco-gabbro trondjemite dolerite peridotite. Sed/chem chert+mudstone.


RockSuiteCom:
An iron enriched suite on the AMF diagram, includes basalt oversaturated in silica with hypersthene and pigeonite amongst modal pyroxene. With or without olivine.


RockSuiteCom:
Dark olivine bearing andesite, porphyritic volcanics with plagioclase (labradorite-oligoclase), pyroxene, hornblende and/or biotite. QAPF diagram fields 9 and 10.


RockSuiteCom:
Basalts of tholeiitic, calc-alkaline and alkaline association Al2O3 + 16% usually with phenocrysts of plagioclase.


RockSuiteCom:
No good defn.  K-trachybasalt is the potassium = of hawaiite TAS field S1. K2O & MgO both +3% & K2O=2Na2O.Also Hi-K andesites with K2O > 2.5% & now all volcanic rocks:basalts,andesites, trachytes plotting above a line SiO2 to K2O on Peccerillo 1976 dgrm)


RockSuiteCom:
Absarokite trachyandesite with phenocrysts of olivine and augite and banakite with less olivine and augite and more sanidine. (orthoclase bearing basalt).


RockSuiteCom:
Molar Na2O + K2O exceeds Al2O3 with acmite + sometimes sodium-metasilicate in CIPW norm usually alkali pyroxene and/or alkaline amphiboles in mode


RockSuiteCom:
Deep-seated, dominantly dioritic rocks with coarse-grained-euhedral hornblende, poikilitic 
feldspar, includes meladiorites, gabbros,hornblendites + pyroxenites with abundant hydrous mafic minerals + granodioritic, monzonitic, syenitic + lamprophyres


RockSuiteCom:
Several basalts in the TAS diagram no normative nepheline. Rocks not alkali in character, TAS field B accessory foids, Ti-augite + olivine (normative nepheline). (Two of these don't seem to me to agree).
