Fifteen granite samples contain hornblendes and show a negative correlation between P_2 O_5 and SiO_2, indicating that the JM is an I-type granite. All the granites are enriched in LREE relative to HREE, with negative Eu anomalies(Eu/Eu*=0.56-0.81), and have similar trace elements ...
S-type granites always contain more Al than the amounts of Na, Ca and K in the rock required to form feldspars, primarily owing to their derivation from source components that had previously been weathered. Those rocks are therefore always saturated in Al, or peraluminous. Many I-type granit...

(S-) type granites. This finding provides clear evidence for rocks other than the trondhjemite-tonalite-granodiorite suite in the Earth’s earliest continental crust. Considering that I- and S-type granites are typical of modern convergent plate margins, the presence of a high proportion of Jack...
