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。

Methods Based on the analysis for the inner structural CL images of zircons, the U-Pb ages and Hf isotopes of zircons from the host granites, mafic microgranular enclaves and diorite dykes have been discussed using in situ zircon analysis of the LA-ICPMS and MC-ICPMS.
