| 摘 要： | 地处板岩镇断裂与安康断裂之间的镇（安）旬（阳）盆地，泥盆系一中三叠统地层发育齐全，沉积构造及生物化石丰富，岩相较清晰，层序界面保存较完整，是南秦岭陆内造山带开展层序地层与盆地分析研究较为理想的地区。本文对镇旬盆地地层、层序特征进行总结，识别厘定了十一个层序不整合界面，划分了十个不整合界限地层单位，建立了盆地岩石地层格架、层序地层格架，并对盆地的形成、发展、演化进行了初步分析，探讨了沉积作用与矿产的相互关系。

| Abstract: | Zhen (An) Xun (Yang) basin is located between the Banyanzhen fault and the Ankangfault, which has good records for the stratigraphy deposited during Devonian-middle Trias-sic, in which sedimenrary structure, fossils, lithofacies and stratigraphical boundaries are easyto find and identify. So,it is idealistic region to study succession stratigraphy and basin analy-sis of intracontinentaI orogenic belt in the southern Qinling- Having summed up stratigraphyand succession features, the frameworks, including rock stratigraphy framework and succe-sion stratigraphy framework, are established. Besides, eleven stratigraphical discontinuityhave been suggested in which the deformation, development and evolution of the basin areanalysed and the relationship between sedmentary and mineral resources are concerned. |
