项目摘要
9422941 Rajan The aim of this research is to elucidate the relationship between grain boundary crystallography and grain boundary wetting in mineral systems. The specific experimental focus is determination of the crystallography characteristics and orientation relationships of grains that have their mutual boundary wetted and comparison to these boundaries that are not wetted. The methodology to be utilized involves examination of grain orientation and grain boundary misorientation data (obtained by SEM and TEM) coupled with Rodrigues-Frank representations of the data. This approach will develop characterization techniques that capture localized information in a statistically meaningful manner. Wetting properties are of interest to Earth scientists because they affect grain boundary transport, a fundamental process by which bulk transport of chemical species through rocks containing static fluids occurs. In addition, melt films along grain boundaries affect seismic velocities and attenuation within the solid Earth and rheological properties of materials in seismic zones.
9422941拉詹:本研究的目的是阐明矿物体系中晶界结晶学与晶界润湿之间的关系。具体的实验重点是确定相互边界润湿的颗粒的结晶学特征和取向关系,并与未润湿的这些边界进行比较。所采用的方法包括检查晶界取向和晶界错位数据(通过扫描电子显微镜和透射电子显微镜获得),以及数据的罗德里格斯-弗兰克表示法。这种方法将开发以统计意义的方式捕获本地化信息的表征技术。润湿特性是地球科学家感兴趣的,因为它们影响晶界传输,晶界传输是化学物质通过含有静态流体的岩石发生大量传输的基本过程。此外,沿晶界的熔体薄膜影响固体地球中的地震速度和衰减,以及地震带中材料的流变性。
