| 1 | 岩石中纳米粒子层的观察厘定及其地质意义显示文摘纳米粒子具有个体极小(≤100nm),大小均一,多元物质和功能繁多的特点。岩石剪切滑移面纳米粒子层最早发现于美国圣安德列斯断裂带的花岗质糜棱岩中,后相继在国内外一些地区的不同岩类中观察到。在剪切滑动作用下,具有圆度和球度的纳米粒子可被变异,并形成层状结构和各种构造型式。对岩石中纳米粒子层的成因有着不同的观点,我们倾向于剪切摩擦的主导作用,纳米粒子层可称谓摩擦-粘性薄层带。纳米级尺度粒子的力学、物理和化学效应是多种的、新奇的,因此,岩石纳米粒子层的研究有着重要的理论和实践意义。目前有关方面的研究工作,国内外都处在起步阶段。 | 孙岩 陆现彩 舒良树 刘浩 | 2008 | 地质力学学报2008，14，1： | 11 |

| 3 | Nano-texture of penetrative foliation in metamorphic rocks显示文摘By observing four samples obtained from Jiangxi Province, China, under the scanning electron mi-croscope (SEM), we discovered that nano-particle layers were commonly formed on sliding planes of the penetrative foliation in metamorphic rocks. We also successfully reproduced this phenomenon with a tri-axial pressure experiment. Having gone through the granulitization-alienation-partition in the shear sliding process, the nano-particles (40-95 nm in diameter) display different individual shapes and dis-tinct layered textures. This nano-confinement layer is essentially a frictional-viscous stripe with vis-cous-elastic deformation. In the micro-domain stripe, activities in structural stress field-rheological physical field-geochemical field are very dynamic, corresponding to the three stages (i.e., shear sliding strengthening-weakening-exfoliating) of the foliation development in metamorphism rocks. As such, the viscous-elastic deformation behavior helps shed light on the understanding of the micro-dynamic mechanism of the structural shearing. | SUN Yan LU XianCai ZHANG XiHui LIU Hao LIN AiMing | 2008 | Science China Earth Sciences2008，51，12： | 5 |
| 4 | 江西九瑞矿集区硅质断裂磨砾岩带的厘定及其成岩成矿意义显示文摘在九瑞矿集区研究叠合断裂和叠加成矿作用的基础上,我们进一步详细研究了出露在洋鸡山-丁家山-望夫山一线的硅质角砾岩,指出它们不是原先认为的石炭系沉积硅质岩,而应属于一种断裂磨砾岩,并深入探究其形成过程及与成矿之关系。断裂磨砾岩是断裂分带结构成熟的标志之一,多在剪切作用和热液作用下,断裂岩石经硅化-破裂-碎裂-粉碎-研磨,形成具有一定圆度和球度,大小差异较大的磨砾或磨粒,且又会反复的集结-破碎,不断拓宽断裂构造形成磨砾-角砾岩带。本文研究的断裂磨砾岩,呈北东向展布,延长达十几千米。成分上以硅化角砾岩为主,SiO2含量一般大于90%,石英颗粒由隐晶到显晶。一些角砾岩中含Fe2O3较高,有可能是原先的硫化物经氧化形成的褐铁矿。本区洋鸡山-丁家山-望夫山一线产出的断裂磨砾-角砾岩带,很可能是燕山期构造-岩浆-成矿事件的产物。在城门山和武山铜矿,我们之前的工作己发现存在产于泥盆系五通组和石炭系黄龙组层滑构造体系中的黄铁矿角砾岩,则有可能属于海西期同生断裂活动的产物。因此,这些不同的角砾岩具有多阶段活动和叠加成矿的特征。本文还进一步指出,九瑞地区其他层位(如泥盆系与志留系之间、志留系与奥陶系之间)发育的层滑构造体系和断裂角砾岩及热液蚀变岩,也很可能是成矿有利部位,值得今后找矿工作的关注。 | 蒋少涌 徐耀明 周巍 朱志勇 孔凡斌 孙岩 | 2012 | 岩石学报2012，28，10： | 5 |
| 5 | 断裂剪切带中的纳米结构与成矿作用显示文摘纳米科学已涉及从信息学到地学的各个领域,成为这个时代一个标志性的关键词。近十多年来,国内外的纳米地学研究,在实践、理论和实验等诸方面都取得了迅速的进展。该文运用4F (Fact, Formation, Function and Formulation,即事实观察、形成机理、功效作用和计算模拟)研究方法,利用扫描电子显微镜(SEM)和透射电子显微镜(TEM)对断裂剪切带中的纳米结构与成矿作用进行了样品观察和综合分析。首先,作者表述了岩石剪切面上广泛分布的剪切薄壳(膜)的形成、发育和组成,一般脆性剪切的薄壳厚度(h,毫米—厘米级)要比韧性的剪切薄膜(忽米—毫米级)厚,前者是由动态摩擦粘滑滑移引起的,而后者则是由静态蠕滑滑移造成的,且两者均是由纳米矿物和纳米结构组成的。随之,作者集中探讨了作为研究主体的剪切薄壳(膜)中纳米结构的应变变形和生成演化,它们既具有弹性又有粘性的变形特征而不是单一的力学属性。纳米结构的生成—发育—演化,可依剪切变形过程划分为强化(硬化)—弱化(软化)—脆化(退化)三个变形应变阶段,和相应的纳米涂层—纳米弱化—纳米层裂三种类型纳米作用:(1)纳米涂层是一种最基本的纳米作用,在成熟的断裂剪切(带)中,只要有滑移摩擦存在,就会有纳米结构。这种作用能引起有序的纳米结构和定向结构,包括单体纳米颗粒(通常直径d=40~80 nm)—复体纳米颗粒—多重复体纳米颗粒;纳米粒—纳米线—纳米层;纳米颗粒粒化—异化—再生等。(2)纳米弱化作用是由颗粒粒度减小,瞬时温热,叶理发育和弱势矿物等所致,并可细分为滑动纳米弱化、流变纳米弱化和动力纳米弱化三种类别。(3)纳米层裂作用是一种由动力热作用到静力冷作用诱发的剥离作用,通常沿着纳米结构的劈理面、解理和滑移面开裂。进而,以江西省的金山金矿和广丰滑石矿为例讨论了纳米结构与成矿关系:(1)含金糜棱岩发育过程中的纳米涂层作用成岩,纳米弱化作用成矿和纳米层裂作用形成面理的三个阶段。其重要的是纳米弱化作用期间超糜棱岩的温度能够达到纳米金物质的熔点327℃,并在流变滑移过程中产生集中颗粒型(d=15~35 nm)和分散颗粒型(d=4~8 nm)的金颗粒;(2)滑石矿中高应变反映的纳米结构和纳米作用尤为强烈,具有局部熔融流变,纳米弱化作用阶段的纳米次分层作用非常发育,沿(001)面滑移的叶理厚度仅10~15 nm,且纳米层裂作用更是造成开放性的剥离、裂理作用。上述的研讨,揭示了实质上至少一维的'纳米小疙瘩(nano-orange)在地球物质中无处不在'。这场地学变革——'纳米科学与技术是地球科学的下一次革命(Hochell, 2000)'——大幕才刚刚开启,就促使科研工作者对一些地质现象重新认识,也激发大家去开发'纳米小疙瘩'在地球物质中的'新奇'功效。 | 孙岩 陆现彩 琚宜文 | 2018 | 高校地质学报2018，24，3： | 4 |

| 7 | Nanoparticles Study on the Indosinian Xiaomei Shear Zone in the Hainan Island,China:Implication to Developmental Stage and Formation Mechanism of Nanoparticles in a Fault Zone显示文摘Nanoparticles are widely observed in the natural shear zone and experimental slip faults, which can lubricate the fault and significantly reduce the friction coefficient during seismic slip. But it is still not clear how the nanoparticles develop during the process of sliding. Clarifying the development stage of nanoparticles in a fault zone is critical to understanding the formation mechanisms of nanoparticles and the mechanism of fault weakening from a nanoperspective. In this study, four types of nanoparticles were found in the Indosinian Xiaomei shear zone, including spherical nanoparticles, rod-like nanograins and their aggregations. Ultramicroscopic analyses indicate that polished patches are highly smooth and composed of tightly packed spherical nanoparticles and well orientated rod-like nanograins during slip at high velocities. Meanwhile, the dome nanoparticles were formed by the calcite thermal decomposition due to frictional heat during highspeed sliding. The polygonal grooves are possibly related to high temperature(>900℃) grain boundary sliding deformation mechanisms. However, the porous and rough surfaces are accompanied by a series of holes and parallel 'scratches' during a subsequent low-velocity stage. To ascertain the chemical composition of these nanoparticles, the energy dispersive spectrometer(EDS) test were conducted. The results suggest that materials rich in Fe, MgO and wollastonite are likely to form the rod-like nanograins, while materials rich in SiO2 are likely to form the spherical nanoparticles. | Yang Zhou Baoyun Shen Yi Yan Hailing Liu Yan Yan | 2020 | Journal of Earth Science2020，31，5： | 0 |
