Ophiolites are widespread across the Anatolian plate and formed during the termination of different branches of the Neotethys ocean. The Tekirova ophiolite, situated in the Antalya ophiolite nappes in Southwest Anatolia, originated in the southern branch of the Neotethys. The former ophiolite consists of mantle and crustal sequences, in which, it is predominantly crosscut by the isolated diabasic dikes. Here, we have distinguished two dike types on the basis of their petrographic features and also degree of alteration. The relatively fresh types are generally named as diabase dikes. While the altered types are called as metasomatised dikes, and these dikes display ophitic to subophitic textures. The diabase and metasomatised dikes show enrichment in LILEs and depletion in HFSEs, indicating characteristics of suprasubduction zone ophiolites. This depletion of mobile elements may have been caused by metasomatism. The HFSEs versus HREEs diagrams show that the dikes were formed from 10 to 30% melting of extracted melts from previous mantle melting in which modified by subduction-derived fluids.

蛇绿岩广泛分布于整个安纳托利亚板块，形成于新特提斯洋不同分支的终点。Tekirova蛇绿岩位于安纳托利亚西南部的安塔利亚蛇绿岩推覆中，起源于Neotethys的南支。前蛇绿岩由地幔和地壳层序组成，其中主要被孤立的辉绿岩脉横切。在这里，我们根据岩相特征和蚀变程度区分了两种堤坝类型。较新鲜的类型一般称为辉绿岩脉。改变后的类型被称为交代岩脉，这些岩脉显示出透质到亚透质的纹理。辉绿岩和交代岩脉显示出 LILEs 富集和 HFSEs 耗尽，表明超俯冲带蛇绿岩的特征。这种移动元素的消耗可能是由交代作用引起的。HFSEs 与 HREEs 图显示岩脉是由 10% 到 30% 的熔体形成的，这些熔体是从先前的地幔熔融中提取的熔体，其中被俯冲衍生的流体改性。
