Shoshonite combination is a Si O2 close to saturation
moderate alkali-rich
relatively rich in K
and Fe-poor rock combination; belonging to sub-alkaline series(including tholeiitic and calc-alkaline series) between alkaline series transition type. This paper summarizes the main characteristics distinguish shoshonitic rock material sources petrogenesis and tectonic setting. Because shoshonitic rocks have a special meaning in Genesis science and regional tectonic evolution of the rocks
and is an important symbol of prospecting
so more attention to this combination of rock in recent years.
