查询词典 micas

"It is the most abundant metallic element in Earth's crust, chiefly in bauxite, feldspars, micas, clay minerals, and laterite. It also occurs in gemstones, such as topaz, garnet, and chrysoberyl; emery, corundum, ruby, and sapphire are crystalline aluminum oxide ."

In recent years, the study of excess argon genesis in high-pressure white micas is a hot topic in the field of isotope geochronology.

中文摘要：近年来，高压成因白云母中过剩氩研究成为国际同位素年代学界的一大热点。

In this research project, we have got a series conclusions:(1) there is no excess argon in the high-pressure white micas being in the orthogneiss;(2) The distribution of excess argon in eclogite is positive correlative with the ratio of Mg/, but negative with the ratio of Na/;(3) The in-situ analyses by using the method of laser probe 39Ar-40Ar show that the age radius from central to margin in a single grain of high-pressure white mica in eclogite;(4) There is no any evidence to prove that the excess argon in eclogite comes from fluid;(5) The excess argon in eclogite inherited from primitive rock during high-ultra high pressure metamorphism;(6) There is no excess argon in the eclogite when its surrounding rock is carbonate.

本项目用综合手段，研究了高压白云母中过剩氩的来源、赋存、分布与岩性、产状、矿物元素和矿物显微结构之间的相关关系，以确定过剩氩在高压白云母中赋存的主要控制因素。初步得出了以下结果：1、高压变质的正片麻岩中的白云母中不含过剩氩；2、高压白云母中过剩氩的赋存和Mg/有着正相关关系，而和Na/呈负相关；3、激光微区氩-氩分析表明，榴辉岩中的单颗粒多硅白云母存在年龄梯度；4、初步否定了高压白云母中过剩氩来自于流体的说法；5、初步认定，榴辉岩中多硅白云母中过剩氩主要是在高压-超高压变质过程中由内部继承的；6、在阿尔金及柴北缘等地围岩为碳酸岩的榴辉岩中的高压白云母不含过剩氩。上述研究结果将推动过剩氩成因研究走向深入。

In this paper, the mineralogical characteristics and potassium release performance after activation of dioctahedral micas, from muscovite, sericite to illite, have been studied.

本文对白云母、绢云母到伊利石的二八面体系列云母的矿物学特征和活化释钾性能进行了研究。

For dioctahedral micas, interlayer potassium is not easily released because of the structures being stable, and very few researches can be found corresponding to potassium release after activation.

二八面体型云母结构稳定，层间钾不易释出，活化释钾的难度也较大，而且这方面的研究也不多。

The mineralogical characteristics of dioctahedral micas have been studied by chemical analysis, XRD, IR, DTA, SEM and IEM.

用化学分析、X射线衍射、红外光谱、差热和热重分析、扫描电镜及透射电镜等研究了白云母、绢云母和伊利石的基本矿物学特征。

In the detrital zircon sample FH4, which was collected from lower sandstones of the Fanghushan Formation, the oldest sedimentary strata of the Hefei Basin. HP-UHP mineral inclusions such as coesite, omphacite, phengite and melt inclusions, and other minerals like apatite, quartz, feldspar, white micas were identified by means of micro-laser Raman spectrometer and electron probe.

防虎山组的下部砂岩地层是合肥盆地最古老的中生代沉积地层，在样品FH4中选出了碎屑锆石，通过显微激光拉曼光谱、电子探针的研究发现，锆石中含有柯石英、绿辉石、多硅白云母等典型的高压－超高压矿物包裹体、熔体玻璃包裹体以及磷灰石、石英、斜长石、白云母等矿物包裹体。

Techniques and processes of activation for micas have been investigated. The optimum temperature of muscovite, sericite and illite is different, and at the temperatures the micas are mostly dehydroxylated, but still remain the basic layer structure. Some heat-induced phenomena can be observed in thermal-treated products, and the release potassium is principally slowly available potassium.

对云母样品活化释钾的方法进行了探讨，发现白云母、绢云母和伊利石的最佳释钾活化温度，该温度下云母部分脱羟，但仍保持了原有的基本结构，透射电镜下可见脱羟引起的辐射损伤、热致的晶格位错等结构现象；热产物中速效钾、特别是缓效钾量增加显著。

There are no prominent variations of the micas in Li, F, Mn and Rb between zone c and zone d but sharp changes in these elements between zone d and zone e. In contrast to the primary micas in zone e, the altered micas in zone e show higher in F and Li but lower in Al. From zone a to zone e, the micas do not show remarkable variation in Na+K.

从c带到e带，随着Fe、Mg和Ti的减少，总体上表现为Al、Li递增，F、Mn和Rb递减的演化方向，但Li、F、Mn和Rb在c带和d带之间变化不明显，d带和e带之间却表现出急剧的变化。e带中的次生云母与原生云母相比，前者F、Li高而Al低，从a带到e带，Na+K变化不明显。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
