And we got an aluminogermanate KAlGe〓O〓 and a borogermanate LiBGeO〓, whose structures are analog to paracelsian and cristobalite respectively.

研究了含铝、硼、锌等金属锗酸盐的合成，以碱金属离子作为结构导向剂成功地合成出铝锗分子筛KAlGe〓O〓和硼锗分子筛LiBGeO〓，其拓扑结构与长石Paracelsian和方石英的结构类似。

The primary beryl crystals were crystallized early from the pegmatitic magma in association with rock forming minerals such as quartz, muscovite, albite and spodumene.

原生绿柱石形成于早期岩浆阶段，与造岩矿物石英、白云母、钠长石、锂辉石共生。

Sanidinite (some have transformed to perthite) and quartz inclusions with radial cracks are often seen in the garnet of eclogite. The geothermal gradient of ＜10℃/km is recorded in the early stage mineral assemblage of high-pressure metapelitic rocks with relict aragonite. these features imply a possibility that there may be ultra-high-pressure rocks existed in Altun.

根据榴辉岩中石榴石常见透长石和石英包体，并有放射状裂纹的特征，以及高压变泥质岩石早期矿物组合温压条件记录的地温梯度小于10℃/km和残存文石等特征，不排除区内有超高压变质岩石存在的可能性。

This observation is consistent with comments and observations of earlier investigators who indicated zoning features such as quartz masses, petalite zons and mica selvages.

本观测报告由早期观测者指出的区域特征的注释和观测结论组成的，区域特征包括例如：石英、透锂长石、和云母边缘矿。

Petrologic types for the 23 chondrites are ascertained mainly based on the property of chon-drules and matrix structures of the chondrites, as well as the composition of olivines, structures of pyroxenes and characteristics of feldspars, and so on.

陨石岩石类型的确定，主要根据陨石中球粒及基质的特征，参考其它标志，如橄榄石成分、辉石的结构、长石的特征等进行分类，效果较好。

Melilite-rich Inclusions The different melilite-rich inclusion in Ningqiang displayed the differences in the petrologic features such as its shape, size and texture and so on. For example: their shape can be irregular, lump, subglobe, and globe.

不同的富黄长石包体显示出在形状、大小和结构等特征的差异，例如：它们的形状可以为不规则的，团块形的、准球形和球形的。

The alkali rocks include potassic alkali rocks and natric alkali rocks.

碱性岩：典型的碱性岩为硅不饱和，出现霞石、白榴石等似长石类矿物。

The saccharoidal albite zone, the second zone of Altay No. 3 pegmatite, is composed of two different fabric rocks from the field observation, and is a main zone for deposition of beryllium, phosphrus and rare-earth elements.

阿尔泰3号伟晶岩脉糖粒状钠长石带明显由两种不同组构的岩性组成，而且该带是3号脉主要的Be矿化带，也是P、REE最重要的沉淀场所。

The studies on mineral geochemical for Erdaogou gold deposit located in the west part of Liaoning province indicate that it is characterized by low temperature mineral association such as pyrite, chalcopyrite, galena, sphalenite, telectrum, quartz, seriate, calcite, adual etc.

通过对二道沟金矿床矿物学的详细研究和对比，表明该矿床低温热液矿物组合和低温热液蚀变十分发育；与典型的冰长石-绢云母型浅成热液金矿的矿物组合十分相似；其应属于与流纹熔岩及其火山碎屑岩密切相关的浅成热液型金矿床

The middle oil-member is characterized by medium-sized sandstone and pebbled sandstone, with fair sorting and subangular sphaericity. Rock types mainly were feldspar debris sandstone.

中油组主要沉积中砂岩和含砾中砂岩，粒度整体较粗，分选性较好，磨圆度以次棱角状为主，岩石类型为长石岩屑砂岩。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
