中文简介: | 本课程全面介绍了成岩矿物的晶体结构、晶体化学和键合。介绍了晶体结构和晶体对称性与折射率、弹性模量、地震速度等物理性质的关系。它调查了硅酸盐、氧化物和金属矿物在行星内部和表面的分布,并讨论了导致它们形成的过程。它也解释了为什么钻石是硬的,为什么云母会分裂成薄片。 |
课程简介: | This course provides a comprehensive introduction to crystalline structure, crystal chemistry, and bonding in rock-forming minerals. It introduces the theory relating crystal structure and crystal symmetry to physical properties such as refractive index, elastic modulus, and seismic velocity. It surveys the distribution of silicate, oxide, and metallic minerals in the interiors and on the surfaces of planets, and discusses the processes that led to their formation. It also addresses why diamonds are hard and why micas split into thin sheets. |
