22b), samples from the John Lee Brook and Utopia granites plot in the fields of high-K; whereas the sample from the Wellington Lake Granite is associated with the shoshonite
Besides, the granite member of the HP displays a slightly more potassic character by plotting within the shoshonite
The magmatic series of these intrusive bodies are shoshonite
and high K calc-alkaline and are of the I type (Ghorbani, 2013).
In order to separate calc-alkaline series with low potassium, average potassium and high potassium and shoshonite
ones,  diagram is used that is based on K2O quantities in SiO2.
The bimodal volcanic rocks like to East Africa rift, consisted of kamafugite, carbonatite, Shoshonite
, rhyolite and/or trachyte.
is an alkali-rich ([Na.sub.2]O + [K.sub.2]O > 6.5 wt %) trachyandesite that occurs in continental rift, collisional and arc settings (Rogers and Setterfield 1994).
The focus of much of this exploration is the Ordovician shoshonite
volcanics and related monzonitic intrusions of the central and eastern portions of the Lachlan Fold Belt or Orogen.
1989), samples from the MBG plot in the fields of high-K and shoshonite
series, whereas those from the MPG fall into the field of medium K (Fig.
The volcanic rocks of the Nangqen Basin include trachytes, latites, shoshonites
, tephrites, tephriphonolites, and phonotephrites that erupted 38.7 Ma ([sup.40]Ar-[sup.39]Ar plagioclase age) .
The rocks of the chilled margins and the central facies are classified as tephrites, basalts, basaltic andesites and shoshonites
whereas the pegmatoid facies includes the most evolved rocks: andesites and dacites (Fig.
They are clearly different from crustal contaminated, postcollisional Islamic peninsula shoshonites
and ultrapotassic rocks.
