对于大陆造山带内部的超基性岩体,除了蛇绿岩成因之外还有其他或许更为合理的解释。例如,位于新疆托克逊库米什地区南天山北缘的榆树沟麻粒岩和橄榄岩分别代表早古生代时塔里木板块北部大陆地壳莫霍面附近的下地壳底部与上地幔顶部的岩石,由于应变的局部化,被剪切分割成两个透镜状冲断岩片,顺着切割整个地壳直达上地幔顶部的韧性剪切带被挤出,最终呈固态挤侵到中地壳内绿片岩-低角闪岩相的变沉积岩(构造片岩、长英质糜棱岩)之中。最后,两个构造透镜体被剪切叠合到一起。榆树沟麻粒岩-橄榄岩地体为研究塔里木板块北部大陆地壳古莫霍面及其附近的岩石流变学与地球物理性质提供了一个十分难得的研究基地,因为大陆古莫霍面很少直接出露地表。榆树沟麻粒岩-橄榄岩组合的地体的大地构造意义与蛇绿岩所代表的截然不同。
For the ultramafic rocks within the continental orogen, there are other possible explanations besides the origin of the ophiolite. For example, the Yushugou granulites and peridotites located in the northern margin of the southern Tianshan Mountains in the Tuikesun Kumiss region of Xinjiang represent the rocks at the bottom of the lower crust and the upper mantle near the Moho in the northern part of the Tarim plate during the Early Paleozoic. Strain localization is split into two lenticular thrust fragments, extruded along the ductile shear zone that cuts the entire crust up to the top of the upper mantle and finally reaches the crust in the middle crust - low angle Metamorphic rocks of the amphibolite facies (tectonic schists, feldspar mylonites). Finally, the two textured lens bodies are sheared and laminated together. The Yushugou granulite-peridotite terrane provides a very valuable research base for the study of the rheology and geophysical properties of rocks in and around the northern continental crust in the Tarim plateau, Expose the surface. The tectonic significance of the Yushugou granulite-peridotite assemblage is completely different from that represented by ophiolite.
