| 摘 要： | 本文以江苏连云港地区变质基底的倾滑断裂带为例,通过透射电镜观察研究,对地壳中深层位中的自由位错、位错壁和亚颗粒等流变特点进行鉴定,并对位错密度、流动应力和流变速率等流变参数统计计算。其研究成果可资同浅层位、深层位的流变特征进行对比,并可作为研讨造山作用、变质作用和成矿作用的科学依据。

| Abstract: | Taking dip-slip fault zones of the metamorphic basement in the Lianyungang area, Jiangsu Province as an example, theological features of the free dislocation, dislocation wall, subgrain, etc. have been distinguished in this paper, and theological parameter, the dislocation density, flow stress, strain velocity, etc. have been calculated as well with a transmission electric microscope (TEM). The research results are not only compared with the rheological characteristics of the shallow and deep levels in earth crust, but they are also regarded as the scientific foundations for studying orogeny, metamorphism and mineralization. |
