通过对Serre地区中部(意大利南部Calabrian岛弧两个海西期英云闪长岩体在地质学、岩石学及地球化学(主要元素及V、Cr、Ni、Rb、Sr、Y、Zr、Nd、Ba、La、Ce)详细研究,可将其归属为两个不同构造单元(即Polia—Coparello和Stilo二个构造单元)。野外关系、岩相学及地球化学特征表明,这两个英云闪长岩体的成因是相同的,并同属于一个极不均匀的深层杂岩体。据这一结论和进一步的Rb/Sr同位素研究结果,两个岩体间的构造接触更可能是一剪切带,而不是推覆构造。 Serre侵入体中的英云闪长岩与主体花岗闪长岩的相互关系及地质特征表明,二者属不同的岩浆源。
Based on the studies on the geology, petrology and geochemistry of the two Hercynian-type diorite bodies in the central Serre region (Calabrian Island arc in southern Italy) and the major elements V, Cr, Ni, Rb, Sr, Y, Zr, Nd , Ba, La, Ce) can be attributed to two different tectonic units (ie, Polia-Coparello and Stilo) .The field relationship, lithofacies and geochemical characteristics show that these two Feiyun The origin of the diorite body is the same and belongs to a very inhomogeneous deep complex. According to this conclusion and further Rb / Sr isotopic studies, the structural contact between the two rock mass is more likely to be a shear Not the nappe structure.The correlation and geological characteristics of the dacite and the host granodiorite in the Serre intrusive body show that they are different magmatic sources.
