摘要:
秦岭造山带地处华北板块与扬子板块结合带，经历了复杂的构造演化过程，其板块拼合机制及碰撞时限一直备受争议。通过对北秦岭五朵山黑云母二长花岗岩进行年代学、地球化学和Sr-Nd-Hf同位素组成研究，以期对北秦岭早古生代构造演化进行约束。五朵山岩体至少存在2期侵入，分别为431 Ma和417 Ma。岩石具有高硅(SiO2=71.16%~74.22%)，富碱富钾(K2O+Na2O=7.16%~8.88%，K2O/Na2O=0.69~2.34)，过铝质(A/CNK=1.01~1.19))等特征。岩石稀土元素总量总体偏低，轻、重稀土元素分异较强，呈右倾配分模式，具轻微的负Eu异常。富集大离子亲石元素Rb、Th、U，亏损高场强元素(Nb、Ta、Zr)及Ba、Sr，在岩石类型上属于I-S过渡型花岗岩类。五朵山花岗岩具有相对低的(87Sr/86Sr)i值(0.70581~0.71093)，εNd(t)值为-6.48~-3.18，对应的Nd的二阶段模式年龄为1.42~1.69 Ga; 绝大多数测点具负的εHf(t)值(-6.9~-0.1)，tDM2=1.50~2.34 Ga。同位素特征指示这些花岗岩为古—中元古代地壳物质部分熔融的产物。五朵山花岗岩的形成与二郎坪岛弧与北秦岭微陆块碰撞作用关系密切，属同碰撞-后碰撞型花岗岩，岩浆源区为北秦岭微陆块古老的地壳物质。
Abstract:The Qinling orogenic belt, located at the junction zone of the North China plate and the Yangtze plate, has experienced a complex tectonic evolution process, and the mechanism of plate assembly and the collisional time are controversial.In this paper, the geochronology, geochemistry and Sr-Nd-Hf isotopic composition of the Wuduoshan biotite monzogranite in North Qinling studied to constrain the early Paleozoic tectonic evolution of the North Qinling.Two periods of intrusion were identified in Wudaoshan batholith, which is dating 431 Ma and 417 Ma respectively.The rocks are characterized by high silicon(SiO2 =71.16%~74.22%), alkali and potassium rich(K2O + Na2O =7.16%~8.88%, K2O / Na2O =0.69~2.34)and peraluminous(A / CNK =1.01~1.19).The total REE content is generally low, and LREE and HREE are strongly fractionated, showing a right dipping distribution pattern and slight negative Eu anomalies.They are characterized by enrichment in large ion lithophile elements(Rb, Th, U), relative depletion in high field strength elements(Nb, Ta, Zr)and Ba and Sr.They belong to "I-S" type granitoids.The Wuduoshan granite has relatively low(87Sr/ 86Sr)i values(0.70581~0.71093), and negative εNd(t)values(-6.48 to-3.18), with the corresponding two-stage Nd model age of 1.42 Ga ~1.69 Ga.Most of zircons have negative εHf(t)values(εHf(t)=-6.9~ -0.1), and tDM2 =1.50~2.34 Ga.The isotopic characteristics indicate that the Wuduoshan granite is the product of partial melting of Paleoproterozoic-Mesoproterozoic crustal material.Combined with the tectonic evolution of Qinling orogenic belt, we concluded that the formation of Wuduoshan granite was related to the collision between Erlangping island arc and North Qinling micro-continent and belongs to syn-collisional and post-conllisional type granite, and the magma source is the ancient crustal material of North Qinling micro-continent.
