| 中文摘要 | The paper research on the petrological geochronology and zircon SHRIMP U-Pb of Thongehang diorites, Mian-Lue-Ning area, Southern Shanxi Province, China. The results show that the diorites, which belong to low K cale-alkali series rocks, are characterized by comparative losing of medium-high field strong elements in microelements and comparative enrichment of large ion lithophile elements. The Chondrite-normalized REE patterns of the diorites, which are similar and successive with that of Bikou group marine volcanic rocks, belong to the LREE-rich type with obvious negative anomaly of Eu, reflecting its island-arc volcanic features. It is suggested that there is a relationship between the diorites and the mineralization of Cu, the diorites may be one of source of metallogenic mass, and the diorites may come from the earth's crust or consumingly contaminated by the earth's crust with no remarkable crystallization differentiation. The geological setting of the forming of the diorites was belonging to collision doming-island arc volcanic, and the mineralization was late to the intrusion of the diorites. The diorites has a SHRIMP zircon U-Pb age of 842 +/- 6.5Ma and suggests it belongs to the invasive magma at the late stage of the stratum-Bikou group spilite, and formed by partly melting from Bikou group spilite. The comparative enrichment of LREE of the diorites may relate to inheriting the REE feature of the source of rocks. |
