查询词典 pyrolite

A mass of pyrolite xenolith (such as peridotite andpyroxenide) and high-pressure mineral megacrysts (such as anorthoclase, augite and kaersutite)are found in cone sheets and BS volcanic rocks.

锥状岩席和BS火山岩包含有大量的上地幔岩石包体和高压矿物巨晶(歪长石、普通辉石和钛闪石)。

GroupⅠ, the peridotite inclusions with typical pyrolite textures (metamorphic and deformation textures);(2) GroupⅡ, the peridotite and olivine-pyroxenite inclusions with metamorphic and deformation textures and overlaid mineral reaction textures or relic magmatic crystalline textures or/and cumulate textures; and (3) GroupⅢ, the pyroxenite inclusions with crystalloblastic texture and cumulate textures.

深源岩石包体的岩相学表明，鲁西深源岩石包体具有三种结构类型：①具有典型地幔岩结构的橄榄岩类岩石包体；②具有变质变形结构，并叠加有矿物反应结构以及残留有岩浆结晶结构的橄榄岩、橄辉岩类岩石包体；③具有变晶结构或堆晶结构的辉石岩类包体。

Lherzolite depleted LREE is a relict of original mantle rocks at different degrees of partial melting;harzbugite with U-typed REE distribution patterns is a product of highly depleted pyrolite which has been metasomatized by melt ...

二辉橄榄岩亏损轻稀土，是原始地幔经不同程度部分熔融的残留体。

The major mechanism of formation of the ophiolites and the podiform chromite diposits in the Western Zhungeer area includes partial melting of the primary pyrolite and differentiation of the melt-out materials after they intruded. The differences between the two ophiolite types are related to the degree of partial melting of the pyrolite and depth of formation of magma chambers as well as oxidation state of the magmas.

对西准噶尔地质条件的分析表明：西准噶尔的蛇绿岩与铬铁矿形成于弧后扩张盆地环境，洋壳形成阶段从晚寒武直至中泥盆统，而盆地沉积阶段则从中奥陶延续到中石炭；洋壳推覆时代不一致，在唐巴勒为早志留，玛依勒山为晚泥盆，达拉布特与和布克赛尔则晚于中石炭。

Recent studies of abyssal peridotites show that they are not melt residues of batching or fractional melting of pyrolite directly after melt extraction of MORB. Petrological studies of peridotites from Luobusa ophiolite massif also indicate that the mantle peridotites are not simple residues of primary pyrolite either.

罗布落蛇绿岩橄的镜下观察和岩石化学资料也证明，它不是原始地幔岩经局部熔化后的残余物，而且由来自更深层的地幔过渡带的硅酸盐超高压矿物底辟上升经熔取出玄武质熔体后，再次局部熔化后的残余物。

The Tuyon Basin contains pyrolite inclusions. The mineralogical character of high-pressuremegacrysts, and the Mg*'、 NiO content and petrographic characteristic of volcanic rocks showthat the Tuyon Basin has the characteristics of primitive mantle magmas.

托云火山中含有上地幔岩石包体，高压巨晶的矿物学特征以及火山岩的Mg#、Ni0含量、岩相学特征等证据均表明托云盆地内存在幔源原生岩浆的产物。

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。
