摘要
根据重力、磁力、地震和地面地质及盆地内部结构、构造等多方面资料的分析,认为在克拉美丽山西端的滴水泉附近存在一条基底平移断裂(暂称滴水泉断裂)。其形成时代为泥盆纪至石炭纪,后期经受了较强的变形,其两端分别与克拉美丽-西拉木伦缝合线西端和扎河坝-阿尔曼太缝合线的东端相连接,平面上表现为右行性质,推测是一古转换断层。所以,克拉美丽-西拉木伦缝合线向西到滴水泉附近终止,然后沿滴水泉断裂折向其北东或北东东的北塔山一带,与扎河坝-阿尔曼太缝合线相接。
Based on the analysis of gravitational, geomagnetic, seismic and surfacc geological data as well as data of the internal structure and tectonics of the Junggar basin, a basement strike-slip fault, called the Dishuiquan fault, is found near the Dishuiquan area at the west end of the Kerameili Mountain in the northeast Junggar basin. The fault was formed in the later Paleozoic and deformed intensely in the later stages. Now the two ends of the fault respectively link up with the west end of the Kerameili-Takezale ophiolite zone and the east end of the Zaheba -Armentay ophiolite zone, showing right-lateral separation in plan. It is inferred that the Dishuiquan fault is a transform fault. The Kerameili-Xar Moron suture zone is therefore ended by the Dishuiquan fault in the west, and then turns along the Dishuiquan fault to the vicinity of Beitashan to its northeast or northnortheast, thus linking with the Zaheba-Armentay suture zone.
