查询词典 epidotes

Major conclutions from this study can be summarized as following:1. On mineralogy, rutiles, apatites, epidotes and vein minerals from UHPM rocks were firstly and systematically studied, by detailed petrography and mineral-chemistry investigation, some mineral or mineral assemblage with special composions or texture were firstly found in UHPM rocks from Sulu-Dabie, for example, corrudum, magnesite, high-Ti biotite and garnet were found as inclusions in rutiles from eclogites, Nb-Fe rutile and zoned Si-Y apatite were found in gneiss, epidote / allanite with euhedral zones like magmatic genesis were found in elogites and gneiss, a lot of minerals with high REE, HFSE, LILE and volatiles were found in veins of gneiss.

在矿物学方面，首次较为系统地研究了超高压变质岩中的金红石、磷灰石、绿帘石等副矿物，并通过详细的岩相学和矿物化学研究，首次在苏鲁-大别超高压变质岩中发现了一些具有特殊成分/结构的矿物或矿物组合，如在榴辉岩金红石中发现了刚玉、菱镁矿、高钛黑云母和石榴石矿物包裹体，在片麻岩中发现了Nb-Fe金红石和具有自形环带结构的高Si-Y磷灰石，在榴辉岩和片麻岩中发现了具有类似岩浆成因的自形生长环带结构的绿帘石/褐帘石，在片麻岩的脉体中发现了大量富含稀土元素REE、高场强元素HFSE(Nb、Ta、Zr、Ti)、大离子亲石元素LILE(K、Th、U、Sr、Ba)，以及挥发性组份(CO_2、F、P、S)的特殊矿物，丰富并提升了超高压变质岩的矿物学研究。2。

Epidotes are extensively seen in various metamorphic rocks of the BikouGroup, especially in such metabasites as greenschist and blueschist.

绿帘石广泛分布于碧口群的各类变质岩石中，但以变质基性岩为主。

Epidotes from different samples show considerable compositional variation,whereas those from the same sample are quite similar in composition, indica-ting that their composition is related.

s=0.23—0.37，但多为0.30—0.32，在不同样品中绿帘石成分变化很大，但同一样品中绿帘石变化不明显，说明其成分与全岩成分有关。

This dissertation focus on rutiles, apatites epidotes and vein minerals from CCSD drill core and outcrops of Sulu-Dabie UHPM rocks, by detailed study of petrography, petro-chemistry, and mineral-chemistry, the implication of these minerals to UHPM and continental subduction-exhumation were discussed.

大别地表超高压变质岩中的这些副矿物和脉体矿物为主要研究对象，通过详细的岩相学、岩石化学、矿物化学等研究，对这些副矿物在超高压变质作用及大陆深俯冲—折返过程的指示意义进行了较为深入的探讨，在以下几个方面取得新的认识：1。

As for epidotesfrom blueschist, X_=0.22--0.36, and their composition varies remarkablyeven.in the same sample. In general, fine--grained epidotes contain relativelylow ps while things are just the opposite for coarse--grained ones whichcommonly exhibit zonal structure characterized by the gradual decrease of pstowards the core, suggesting that the bluescbist might have experienced apressuree--decline metamorphic process.

s=0.22—0.36，其成分在同一样品中也有很大变化，一般细粒者ps分子少，而粗粒者ps分子多，且常发育环带结构，向中心ps分子减少，说明蓝片岩可能经历了一个以降压为特征的变质过程。

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。
