为了进一步研究大洋板片俯冲作用对兴蒙造山带岩石圈地幔性质的改造,以吉林中部地区四合屯组安山岩为研究对象,开展LA-ICP-MS锆石U-Pb定年和岩石地球化学研究。安山岩岩浆成因锆石的206Pb/238U加权平均年龄为223.6±2.1 Ma,表明其形成于晚三叠世。安山岩的SiO2含量为57.60%～64.50%,全碱(Na_2O+K_2O)含量为4.20%～7.20%,Al_2O3含量为15.39%～17.35%,TFe_2O3含量为5.45%～7.24%,TiO2含量为0.87%～1.43%,具有较高的MgO(2.05%～4.24%)、Cr(37.7×10-6～92.2×10-6)含量以及Mg~#值(41～54),为钙碱性岩石。安山岩样品富集大离子亲石元素(如Rb、K、Sr)和轻稀土元素,亏损高场强元素(如Nb、Ta、Ti)和重稀土元素,并展现轻微的Eu负异常(δEu=0.70～0.98)。这些地球化学特征表明,四合屯组安山岩可能源自于经历俯冲流体交代过的地幔楔,在其后续岩浆演化阶段中还发生了磷灰石、斜长石和角闪石等矿物的分离结晶作用。结合区域地质相关资料分析可得出,吉林中部四合屯组安山岩的形成与古亚洲洋最终闭合所引发的造山后伸展构造环境密切相关。受古亚洲洋长期俯冲作用的影响,兴蒙造山带东部吉林中部晚三叠世四合屯组安山岩的地幔楔岩浆源区仍保留早期板片俯冲作用的地球化学记忆。
Abstract：To further investigate the effect of oceanic plate subduction on the modification of the lithospheric mantle in the Xing'anMongolia Orogenic Belt,this study focuses on the andesite from Sihetun Formation in central Jilin Province.We conducted LAICP-MS zircon U-Pb dating and whole-rock geochemical studies.The weighted average 206Pb/238U age of magma-related zircons from the andesite is 223.6±2.1 Ma,indicating that the andesite formed in the Late Triassic.The andesite has a SiO2 content ranging from 57.60%to 64.50%,total alkali(Na_2O+K_2O) content from 4.20%to 7.20%,Al_2O3 content from 15.39%to 17.35%,TFe_2O3 content from 5.45%to 7.24%,and TiO2 content from 0.87%to 1.43%.It also has relatively high MgO(2.05%to 4.24%),Cr(37.7×10-6 to 92.2×10-6),and Mg~# values(41 to 54),classifying it as calc-alkaline.The andesite samples are enriched in large ion lithophile elements(e.g.,Rb,K,Sr) and light rare earth elements(LREEs),depleted in high field strength elements(e.g.,Nb,Ta,Ti) and heavy rare earth elements(HREEs),exhibiting a slight negative Eu anomaly(δEu=0.70 to 0.98).These geochemical features suggest that the andesite from Sihetun Formation likely originated from the mantle wedge modified by subduction fluids,with further fractional crystallization of minerals such as apatite,plagioclase,and hornblende during magma evolution.In combination with regional geological data,these observations suggest that the formation of the andesite from Sihetun Formation in central Jilin Province was closely related to a post-collisional extensional tectonic setting triggered by the final closure of the Paleo-Asian Ocean.Influenced by the prolonged subduction of the Paleo-Asian Ocean,the mantle wedge magma source region of the Late Triassic andesite from Sihetun Formation in central Jilin Province,eastern Xing'anMongolia Orogenic Belt,still preserves the geochemical signature of early plate subduction.
