| 英文摘要 | Xiaoshitouquan ore district was a new prospect district and located on the eastern part of Haerlike island-are. Based on the study of the host rock, it shows strong characteristics of island-arc suites. Rhyolitic porphyry, dacitic porphyry and dacite are the main host rocks. SiO2 range from 51.96% similar to 72.58%, and Na2O + K2O are in 3.1% similar to 7.73%, which shows the calc-alkaline characteristics based on the Rittmann index. The BEE showing steep patterns ( rich in light BEE and depleted in heavy BEE) with Eu negative anomaly, which means plagioclase left in the magma chamber or processed fractional crystallization. The average initial Sr value is 0.7043, and epsilon Nd(t) is 4.7, which means a mixed magma source of mantle and crust. After comparison with volcanic rocks in Dananhu island-are, there is some difference between two places. Haerlike island are lack of Adakite different from Dananhu, the characteristics of trace elements and isotopes show the volcanic rocks are contaminated by the mantle wedge. Therefore we believe different types of deposits should be found here such as hydrothermal poly-metallic deposit. |
