The harzburgite inclusions in western Liaoning could be relicts of partial melting of the mantle-derived peridotites; the amphibole-bearing spinel lherzolites could be representative of Phanerozoic accreted lithospheric mantle; the pyroxenite xenoliths with cumulate textures would be the cumulates of magma derived from asthenosphere in the upper mantle; the granulite and gneisses with crystalloblastic textures could be derived from the lower crust in the region.

The 43-57km lithospheric mantle could be consist of a suite of cumulates with crystalloblastic texture, cumulate texture and relic magmatic crystalline textures, such as orthopyroxenite, websterite, clinopyroxenite and olivine-pyroxenite. The lithospheric mantle of 43km to Moho discontinuity could be spinel harzbergite and minor spinel lherzolite, in which the spinel harzbergite and minor spinel lherzolite xenoliths are discoveried. The Moho in the region could be an transitional zone composed of cumulates in petrology.

它既包括了具变晶结构的斜方辉石岩、二辉石岩，又包括了具有残留岩浆结晶结构与堆积结构的橄辉岩和辉石岩；向上至莫霍面，应为尖晶石方辉橄榄岩，并有少量尖晶石二辉橄榄岩，本区发现的尖晶石二辉橄榄岩(T7-21)和尖晶石方辉橄榄岩(T35、T58)可能来自该层；本区莫霍面在岩石学上可能为一个由堆积岩组成的过渡带(3～5km)。

The texture ofserpentine can be divided into the following category: micro ballistic texture, lepidoblastictexture, filer ballistic texture, replacement remnant ballistic texture, porphyritic texture.

栾川蛇纹石玉结构可分为：显微变晶结构，鳞片变晶结构，纤维变晶结构，交代残余结构，似斑状变晶结构。

It has six kinds of texture: felt-like cryptocrystallineballistic texture, fascicules ballistic texture, radiated ballistic texture, porphyritic texture,gyrated ballistic texture, replacement remnant ballistic texture.

通过镜下分析，栾川软玉的主要矿物成分为透闪石，一般含量在 95%以上，结构可分为毛毡状显微交织变晶结构、纤维束状变晶结构、放射状变晶结构、似斑状结构、旋转结构、交代残余结构。

No direct relationship has been demonstrated between the dir ection of relative plate motion and linear indicators of movement direction on s hallowly dipping foliations, thrusts and faults.

缓倾斜叶理上的运动方向的线状指示物和斑状变晶中的叶理弯曲或叶理交切轴并无直接关系，这是因为FIA的指向受缓倾斜叶理和斑状变晶边缘上产生的、近乎垂直的叶理之间的交切面控制。

There is no direct relationship between linear indi cators of movement direction on shallowly dipping foliations and foliation infle xion or intersection axes in porphyroblasts.

在斑状变晶边缘附近的近乎垂直的交切面中具有一种较早形成或稍晚形成的缓倾斜叶理，这种叶理在后期叶理产生时会被圈闭在斑状变晶中，它可以指示FIA的方位，而且并不受此叶理上的运动方向的影响。
