| 英文摘要 | The appinite suite is a group of hornblende-rich intrusive rocks, which display a lithological compositional range from ultramafic to felsic and can be composed of hornblendite, hornblende gabbro, hornblende diorite, tonalite and biotite granite. With regard to elemental geochemistry, the appinites show a low-K tholeiitic, calc-alkaline or shoshonitic affinity, with enrichment in large ion lithosphere element and light rare earth element. The appinitic parental magmas generally originate from partial melting of subcontinental lithospheric or asthenospheric mantle modified by oceanic-slab subduction. These pristine mafic magmas then undergo fractional crystallization, crustal assimilation or mixing with crustal melts, and form different endmembers of the appinite suite. As is typical for appinitic magmas, it is water that not only determined its amphibole-dominated mineralogical character, but also shaped its calc-alkaline geochemical affinity. From the perspective of geodynamic and structural constraints, the appinite suites are usually considered to be related to the ridge-trench interaction or post-collisional geodynamic process. Meanwhile, they show a close spatial/temporal and genetic connection with regional tectonism. Based on the field co-existence and geochemical similarity, the appinite suites have a close petrogenetic relationship with high-Ba-Sr granites and Late Archean sanukitoids. The systematic research on these analogues not only contributes to the study of appinite genesis, but also helps to decipher the continental crustal growth and differentiation, as well as the tectonic regime in the early history of the Earth. The last but not the least, numerous Late Paleozoic appinitic complexes from the northern margin of North China Craton should be incorporated into the new backup research proposal. |
