Abstract:The Nuri superlarge polymetallic deposit is the first scheelite deposit recently found in the Gangdese metalloginic belt. Based on the geological suvery, this study carried out geochemical analysis, zircon UPb chronolgy, Re- Os isotope and Sr- Nd- Pb- Hf isotope for the magmatic rocks in the mining area. The results show that the magma sequence evolved from quartz diorite porphyrite (93.42+0.76 Ma), to andesite (92.04+0.71 Ma), biotite granite (50.46+0.56 Ma), granodioriteporphyry (24.83+0.21 Ma), suggesting an evolution from the high potassium calcalkaline to calcalkaline series. Quartz diorite porphyrite has SiO2of (57.19%~58.23 %) and K2O of (1.71%~2.2%), high total alkalinity of (5.28%~5.77%), A12O3 of (14.14%~16.45%) and medium CaO of (2.33%~4.11%). It is also characterzied by Rittmann index of (1.79~2.07) and A/CNK of (0.77~0.82), Mg# values of 7.19~49.51, enrichment in Rb, U, Pb, Ba and Ths; LREE/HREE of (10.25~11.07), enrichment in LREE relative to HREE, and weak Ce anomaly, lower (87Sr/86Sr)t of (0.7039~0.706), suggesting that quartz diorite porphyrite is characterisitc of adakite. Andesite contain SiO2(54.17%~60.27%), K2O (1.78%~225%), A12O3 (17.89%~22.65%), and Rittman value σ(1.32~2.34), A/CNK (0.91~1.54), Mg# (48.14~52.04). It also enriches in Rb, U, Ba and Th, and distinct differentiation of LREE and HREE with LREE/HREE (9.86~16.94) and obvious Ce anomaly, suggesting the feature of normal island- arc magmatic rocks. Biotite granite contains the SiO2 (64.90%~66.12 %), K2O (2.31%~23.86%), total alkalinity (6.47%~7.01%) and A12O3 (15.52%~16.15%) and CaO (2.33%~4.11%), the σ (1.45~2.17), A/CNK (0.93~1.02), Mg#(28.49~36.55), enrichment of Rb, U, Pb, Ba and Th, and the LREE/HREE (6.26~7.29) and obvious Eu anomaly, and (87Sr/86Sr)t (0.704488~0.704584), suggusting the feature of islandarc magmatic rocks. Granodioriteporphyry contains SiO2 (59.12%~7497%) and K2O (0.83%~3.67%),high total alkalinity (2.77%~6.89%) and A12O3 (11.31%~17.06%),CaO (5.32%~6.22%), the σ(0.24~2.64) and A/CNK(0.75~0.93), Mg#(35.11~51.57), enrichment of Rb, U, Ba and Th and the LREE/HREE(9.866~16.93), Eu anomaly and the (87Sr/86Sr)t (0.705745~0.706073) whcih εHf(t)(2.76716~8.66174), implying that it originated from new- born continental crust and is characteristic of adakite. Re- Os isotope of pyrite shows three phases of mineralization events in the Nuri mining area, suggesting that the magmatic evolution coincides well with the mineralization events in the ore cluster area. This study is of great significance for prospecting in the ore cluster area with different metallogenic time and events.
