| 英文摘要 | Plenty of ultramafic enclaves are included in the Mesozoic high-Mg diorites from the central and eastern parts of the North China block. The geochemical characteristics of the high-Mg diorites were formed through reactions between the ultramafic rocks and low-Mg, felsic magma produced by partial melting of lower crust. Residence timescales of the ultramafic rocks in the hot magma, however, are poorly known. In this work, we have investigated the residence timescales of dunites in hot (similar to 950 degrees C) dioritic magmas from the Tietonggou pluton in western Shandong Province and the Han-Xing pluton in Hebei Province, based on numerical modeling of the diffusional Mg-Fe zonings preserved in the dunites. We show that the residence timescales of dunites in the dioritic magmas are 10(2) similar to 10(3)y. This conclusion is meaningful for understanding the detailed processes of reaction between ultramafic rocks and intermediate-felsic magmas and formation of high-Mg diorites. |
