青石

Six mineral samples are Hannuoba olivine of China, Penghu olivine, Kuanyinshan clino-pyroxene, Lingding clino-pyroxene, Lutao clino-pyroxene and cordierite.

六种矿物样本分别是：中国汉诺坝橄榄石、澎湖橄榄石、观音山斜辉石、岭顶斜辉石，绿岛斜辉石及绿岛堇青石。

A number of microplants with spherical, triangular, polyangular and boat-like shapes have been found both from the early Palaeoproterozoic Dashiling and Qingshicun Formations (ca. 2500- 2400 Ma) of the Doucun Subgroup of the Hutuo Group and the late Palaeoproterozoic Changzhougou and Chuanlinggou Formations (ca. 1800 -1700 Ma) of the Changcheng Group in North China. According to the features of these fossils, such as size, external shape and internal structure, they may belong to unicellular eucaryotic planktons.

在华北地区古元古代滹沱群豆村亚群的大石岭组、青石村组(约2500～2400 Ma)和长城群的常州沟组、串岭沟组(1800～1700 Ma)中存在着大直径的球形和形态呈三角形、多角形及船形微古植物，根据它们的大小、外部形态和内部结构等综合判别，它们可能属于单细胞真核浮游生物。

The main point of this paper lies in the research on the microstructure of the mullite—cordierite sagger, which has been used in the production of Jingdezhen ceramic industry in large quantities for many years, by means of a polarization microscope with ultrathin section together with close connection of the process in the sagger manufacture.

本文主要是利用偏光显微镜和超薄光薄片并紧密结合匣钵的制造工艺，对景德镇市多年来一直在陶瓷生产上大量使用的&莫来石—堇青石质匣钵&进行了显微结构的研究，发现这种匣钵材料的主晶相是堇青石，次晶相是刚玉和莫来石，并发现其中各晶相成团聚状分布；另外在磨制超薄光薄片过程中，发觉其结构较疏松。

A huge chunk of granite rests on a flagstone slantwise, the better part of it jutting out over one of the cliffs; it looks as though that a gust of wind would send it rolling down the cliff.

一块巨大的青石斜斜地搭在一块石板上，大半部分露出在悬崖上，好像风一吹，千斤重的石头便会滚下悬崖去似的，不会掉下去的呢！

Orebodies occur in a fault near the axial region in the southern limb of the Jinjinghe-Hujiamiao inverted secondary anticline in the southern limb of the Hongyansi-Heishan composite syncline. Host rocks are dolomitic rocks in the middle and upper parts of the Devonian Qingshiya Formation. Their spatial distribution is obviously controlled by an interlayer fracture-fissure zone near the axial region in the steeply dipping southern limb of an anticline. Ores are dominantly of nodular and stockwork types and the feature of epigenetic mineralization is very pronounced.

矿体产于红岩寺—黑山复式向斜南翼金井河—胡家沟次级背斜南翼近轴部断裂中，赋矿岩石为泥盆系青石垭组中上部白云质岩，其空间展布明显受背斜陡倾南翼近轴部的层间断裂-裂隙带构造控制，矿石主要有团块状和网脉状，其后生成矿现象非常明显。

MAS precursor powders were uniaxially pressed at 100 MPa employing a lubricated steel cylindrical mold. After sintering at 1450℃ for 2 hours, Single-phase cordierite ceramic is prepared, and its relative density is 95.1%.

以硫酸铝、硝酸镁和硅溶胶为原料，采用溶胶-凝胶法，制得MAS先驱体粉末，XRD表明，该粉末经1300℃的热处理后，完全转变为堇青石。

The chemical and physical properties, phase fabricates and microstructure of the samples that added additions were tested by the testing methods above.
