Some problems of geological study in the western China orogenic belt

摘要: 从大陆研究的视角，认为大陆造山带地质研究是广义上的陆缘地质研究，阐述了陆缘多岛弧盆构造系统及其演化过程，提出造山带内时代相近的一组蛇绿混杂岩带是“古陆缘多岛弧盆格局”的残留，“古陆缘多岛弧盆构造系统”的基本残留形式在平面和剖面上都可能是“网结状”等认识。

Abstract: This paper discusses some important issues concerning pericontinental tectonic evolution， and in board sense, considers the studies of continental orogenic belt geology as that of pericontinental geology. Based on the research of new regional geological material, the authors expound the characteristics and evolutional processes of pericontinental multiarc-basin tectonic system, and suggest a group of ophiolitic melange which nearly formed at the same time represents the relics of pericontinental multiarc-basic tectonic systems. Moreover, the net and knot framework in plane or section is possibly the basic remnant mode of ancient pericontinental multiarc-basin tectonic system.
