研究表明,蛇绿岩剖面是多种多样的,至少可分为两类:第一类以特罗多斯为代表,为具层序性的、厚度较大的洋壳,特征是有席状岩墙群和较厚的堆晶岩单元;第二类以双沟为代表,仅出现镁铁质的喷出岩和侵入岩,洋壳厚度较小,缺少席状岩墙群和堆晶超镁铁岩或堆晶岩不发育。不同的蛇绿岩剖面反映了洋脊之下不同的动力学过程。 The study shows that the ophiolite sections are diverse and can be divided into at least two categories. The first category, represented by Troodos, is a sequence-shaped and thick-skinned oceanic crust characterized by sheet-like Dykes, and thicker units of conglomerate. The second type, represented by Shuanggou, shows only mafic-type extrusive rock and intrusive rock. The thickness of the oceanic crust is small, and the lack of mafic dyke swarms and heap- Magnesite or hematite is not well developed. The different ophiolite profiles reflect the different kinetic processes beneath the ridge.
