| 摘 要： | 盆 山转换是造山带研究中重要的内容。从秦岭和中国西部造山带实际中总结出来的盆 山转换的三种类型、三个阶段，对正确认识秦岭和中国大陆造山带的发展和演化有重要的作用，特别是盆 山转换的第二、第三阶段的提出，有助于重新认识秦岭乃至全球陆内造山带的特征和演化规律，有重要的理论和实际意义。按盆地的属性与造山带之间的转换可以分为三种类型及三个阶段：中－ 新元古代洋壳或过渡性洋壳盆地与造山带之间的转换，形成古秦岭造山带和古中国板块（ 或地台） ；古生代－ 三叠纪板内（ 或地台） 海相沉积盆地与造山带之间的转换形成中秦岭造山带和联合古陆（ 或中国板块） ；印支期以来陆相沉积盆地与造山带之间的转换，形成新秦岭造山带和中国板块（ 或地台） 的裂解。按造山带与沉积盆地之间的结构特征，可以分为造山带与沉积盆地走向基本一致的第Ⅰ类型造山带，造山带与沉积盆地走向不一致，甚至相互垂直的第Ⅱ类型造山带，以及深层构造岩片抽拉 逆冲推覆、叠加在陆相沉积盆地之上的第Ⅲ类型造山带。开合律不是造山带形成与演化的普遍规律 |

| Abstract: | The basin mountain transformation is one of the most important contents in the study of orogenic belt. Its three types and three stages summarized from Qinling and other orogenic belts in western China will play an important role in the understanding of the development and evolution of Qinling and other Chinese orogenic belts. Especially the advocation of the second and third stages of basin mountain transformation will contribute to the realization of Qinling and even global intracontinental orogenic belts. It is of great practical and theoretical significance. Based on the characteristics of basin and orogenic belt, the basin mountain transformation may be divided into three stages and three types. In the first stage, the Meso Neo Proterozoic ocean basin (or transitional ocean basin) transformed into orogenic belt, the Paleo Qinling and Paleo Chinese plate (or platform) were formed; in the second stage, from Paleozoic to Triassic, the transformation from the marine sedimentary basin within the plate (or platform) to mountain formed Meso Qinling orogenic belt and Pangea (or Chinese plate); In the third stage, since Indo Chinese epoch, the transformation from continental basin to mountain formed Neo Qinling and contributed to the rifting of the Chinese plate. The three types of orogenic belts concerning to the structural character between basin and mountain include: the first one, in which the trend of basin runs parallel to that of orogenic belt, the second, in which the trends of basin and orogenic belt are different from or even perpendicular to each other, and the third, in which the deep level tectonic sheet is extracted from draw thrust onto the continental basin. The opening closing law is not universal in the development and evolution of orogenic belt. |
