斑状变晶的

In the second formation of the Langshan group in the Dongshengmiao polymetallic pyrite deposit, metamorphic basic volcanic rock s have been discovered,except quartz keratophyre, with a blastoporphyritic texture containing albite and oligoclase and minor, pyroxen and hornblende.

东升庙硫－多金属矿床狼山群二组含矿地层中，除已发现的变质石英角斑岩之外，又找到具有变余斑状结构（斑晶主要为钠质斜长石，另有少量辉石和角闪石）的变质基性火山岩和变质凝灰岩夹层以及火山岩屑与晶屑。

Most significantly the site provides a number of slide images on the following subjects: Isograds and chemical reactions in regional metamorphism, chemical reactions in rocks, interplay of nucleation and growth, the origin of porphyroblasts, crystal size distributions, feedback mechanisms, the metamorphic aureole of the Bushveld Complex and reconciling theory and observation, the critical overstep for andalusite growth.

网站还提供了一些重要的幻灯片图片，内容涉及到：等变质级、局部变质化学反应、岩石化学反应、晶核形成与发育的相互关系、斑状变晶起源、晶体大小分类及红柱石发育限度评估。

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。

LINEAR INDICATORS OF MOVEMENT DIRECTION MINERAL ELONGATION LINEATIONS, STRETCHING VERSUS FOLIATION INTERSECTION AXES IN PORPHYROBLASTS FIAs AND THEIR RELATIONSHIP TO DIRECTIONS OF RELATIVE PLATE MOTION

线状指示物斑状变晶叶理交切轴板块的相对运动，-运动方向的线状指示物与斑变晶中叶理交切轴FIAs的比较及其与板块相对运动的关系

This occurs because movement di rections on shallowly dipping structures are related to graviational collapse of the thickened orogenic pile rather than push transmitted from the subducting pl ate to the overriding plate.

在斑状变晶边缘上形成的、近乎垂直的叶理在基质中的方位可能在较大范围内变动，因为它们会在稍早期间形成的叶理再活化作用影响下发生转动或遭到破坏。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
