Wang Wei Chunjing Tao -Lou

在阿尔泰山 orogen 的 pelitic granulite 的存在被详细 petrographic 研究和当模特儿的磅假节第一次证实。pelitic granulite 与包含堇青石 + 尖晶石的同等发育不全的一些样品有石榴石 + 堇青石 +K 长石 + 黑云母 + 矽线石 + 斜长石 + 石英的集合。从磅假节决定的 pelitic granulite 的山峰条件包含了 P = 0.5 −0.6 GPa， T = 780 −800 ° C，属于媒介 -- 到低压的类型。锆石标明日期的虾 U-Pb 介绍了 292.8 ±的变形年龄 2.3 妈。pelitic granulite 的发现反映前有在阿尔泰山 orogen 的南部的边缘的高热流动的紧张的环境在期间早二叠，它在阿尔泰山 orogen 的进化上提供重要 petrological 限制。

A new interpretation of the tectonic setting and age of meta-basic volcanics in the Ondor Sum Group, Inner Mongolia

中国科学通报：英文版 (2013)

Chu Hằng Zhang JinRui Wei

The Ondor Sum Group in the central Inner Mongolia is mainly composed of meta-basic volcanics intercalated with ferruginous quartzite and quartz schist,and has been interpreted as slices of oceanic crust or an ophiolite suite of the Early Paleozoic or much older ages.This paper presents new LA-ICP-MS zircon U-Pb dating and geochemical data for the meta-basic volcanics.The results show that zircons in the meta-basic volcanics were derived from complicated sources,most of which may be captured by basic magma from the country rocks or other sources.They yield a large age range from the Late Archean to Early Mesozoic with the youngest age group between 246 and 261 Ma,constraining the protolith of the meta-basic volcanics formed in the Late Permian to Early Triassic.The meta-basic volcanics have an affinity to E-MORB in geochemistry,and also a similarity toward OIB,representing a tectonic setting of limited intra-continental ocean basin.This limited basin might have been related to the continuous extension of the area since the Early Permian and finally closed in the Early Mesozoic.

Metamorphism and zircon U-Pb dating of garnet amphibolite in the Baoyintu Group, Inner Mongolia

中国科学通报：英文版 (2015)

Yaping Chen Chunjing Wei JinRui

Garnet amphibolite in the Baoyintu Group,Inner Mongolia, is mainly composed of garnet, hornblende,plagioclase, quartz and minor rutile/ilmenite. Garnet occurs as porphyroblasts surrounded by plagioclase, forming typical ‘‘white-eye socket’’ texture. Garnet shows grossular content of 0.26–0.28 and pyrope of 0.11–0.13, without significant zoning. Plagioclase is generally zoned with anorthite(An) increasing from core to rim. The P–T pseudosection calculated using THERMOCALC in the system Mn NCKFMASHTO shows that the garnet amphibolite experienced a clockwise P–T path with a peak at*1.3 GPa/725 °C defined from the minimum An content in plagioclase and maximum pyrope content in garnet,followed by an isothermal decompression. LA-ICP-MS zircon dating for the garnet amphibolite indicates metamorphic ages of 399 ± 6 Ma. The peak P–T condition corresponds to a thermal gradient of *18 °C/km, indicating typical medium-pressure type that commonly occurs in orogenic process with crustal thickening. We prefer to interpret this orogenic event to be a result of collision,following the closure of the Paleo-Asian Ocean before theearly Devonian although there is a popular view that the Paleo-Asian Ocean may have lasted to the early Mesozoic.

Progress on grain growth dynamics in sintering of nano-powders

稀有金属：英文版 (2006)

Liu Chunjing Wang Xin Jiang 

Nanostructured materials, characterized by an ultrafine grain size, have stimulated much research interest by virtue of their unusual mechanical, electrical, optical, and magnetic properties. In this paper, the sintering process of nano-powders were reviewed, to which sintering of the traditional materials compared. The microstructural development, i.e., grain growth and densification during sintering as well as the mechanism of crystal surface diffusion and boundary migration were analyzed, and the dynamic models on sintering process were summarized by the relationship of grain growth and pores size, interface diffusion, densification rate, and sintering temperature. Finally, the research tendency of this major on the basis of above models was discussed.
