Geochemical and Sr-Nd isotopic constraints on the origin of Eocene intermediate-basic volcanic rocks from the Liaohe segment of the Tan-Lu fault zone
-
摘要: 研究区位于郯庐断裂南、北两段过渡带构造蜂腰部位,其内充填厚达7000m的古近纪火山-沉积岩系。本文选取火山岩最发育的沙河街组7口代表性钻井进行研究。结果表明,这些始新世火山岩主要为玄武质岩石和粗面质岩石,SiO2含量为45.20%~59.55%,以碱性系列为主。玄武质岩石弱富集大离子亲石元素和Ti,不亏损Nb、Ta等高场强元素。粗面质岩石具有与玄武质岩石相似的地球化学特征,但Sr、P和Ti明显亏损。玄武质岩石的ISr=0.7033~0.7042、εNd(t)=3.56~5.86,粗面质岩石的ISr=0.7035~0.7045、εNd(t)=3.25~4.46,二者的Sr-Nd同位素组成一致,均与OIB相似。综合研究认为,始新世火山岩是弧后拉张环境下,曾遭受俯冲板片流体交代的地幔岩石部分熔融的产物。岩浆在岩浆房内分异演化形成了两种不同类型的岩石。郯庐断裂辽河段从中生代的板缘环境到古近纪陆内裂谷带,其控制因素可能来源于欧亚大陆板块和太平洋板块间的相互作用。在此过程中郯庐断裂系活化并发生大规模走滑运动,导致辽河裂谷盆地同期地幔来源的火山岩浆活动。Abstract: Liaohe segment located in the transitional zone of Tan-Lu fault, is mainly composed of Paleogene volcanic-sedimentary rock series with a depth of 7000m. We conducted detail studies on 7 wells of Shahejie Formation. The results reveal that the Eocene volcanic rocks are mainly composed of basalt rocks and trachytic rocks, with SiO2 contents varying from 45.20% to 59.55%, which were dominated by alkaline lavas. Basaltic rocks were barely rich in Ti, not lack in Nb, Ta. Trachytic rocks show geochemical affinities similar to basalt rocks but depleted in Sr, P and Ti. They have similar Sr-Nd isotopic compositions. Basalt rocks have very enriched isotope characteristics with ISr=0.7033~0.7042, εNd(t)=3.56~5.86, which is consistent with the isotope composition of trachytic rocks (ISr=0.7035~0.7045, εNd(t)=3.25~4.46). Their Sr-Nd isotopes were similar with OIB. Based on the comprehensive studies, we suggested that Eocene volcanic rocks were the product of partial melting of mantle wedge replaced by slab-derived fluid, which intruded above in the back-arc extensional condition. Two distinct rocks generate from magma through differentiation in the magma chamber. The change from destructive settings in Mesozoic to a continental rift environment in Paleogene may be derived from the interaction between Asia plate and Pacific plate. In this process, the large-scale strike-slip movements of Tan-Lu fault controlled the contemporary asthenosphere-derived volcanicity.
