These results suggest that the diagenesis material of the Xiangshan volcanic intrusive complex was derived from crustal sources. The sources either had relatively lower maturity or had more juvenile mantle-derived igneous rocks than the exposed basement metamorphic rocks. Involvement of a small amount mantle-derived magma during the formation of the Xiangshan volcanic-intrusive complex was also possible. The diorite enclave, sub-quartzmonzonitic porphyry and lamprophyre were probably different mixing products between mantle and crust materals.
上述同位素示踪结果充分证实:相山火山-侵入杂岩的成岩物质主要为壳源,但与该区出露的基底变质岩相比,其物源区的成熟度相对较低或含有一定量的火成物质,并且不排除在其成岩过程中少量地幔物质的介入;闪长质包体、次石英二长斑岩及煌斑岩的成岩物质均含有一定量的地幔组分,可能为壳-幔混合作用的产物,只是受地壳物质混染的程度不同而已。

Type III is composed of latite and benmoreite, which are enriched in Al and Ti, with Na2O/K2O≥1.1 and no negative Eu anomaly (δEu=0.93–1.06), and Th/Ta and Ta/Hf ratios indicate a continental intraplate extensional environment. Its formation is probably related to underplating of basaltic magma.
