摘要
本文据大面积的航空磁测资料以及地质调查的最新成果,划分出南天山-北塔里木地块(简称天-塔地块),它被一系列的断裂所围绕。首次指出天山中央深断裂,塔里水中央纬向深断裂和罗布庄-尾亚深断裂(简称罗-尾深断裂)的位置和性质。作者认为,南天山地槽是在一个奥拉谷式的活动带的基础上发展起来的。指出了东西向的沙丘河-库尔勒断折带在天山大地构造演化中的分段控制作用。它类似于火洋板块中转换断层性质的深断裂。
According to the data of large-area aeromagnetic surveying, coupled with the latest geological investigation results, the South Tianshan-North Tarim massif has been delimited. It was surrounded by a series of deep faults. In the paper the location and nature of the Central Tianshan, Central Tarim Latitudinal and Luobuzhuang-Weiya deep faults are pointed out for the first time.The author proposes that the South Tianshan geosyncline developed on a mobile belt of aulacogen type. The paper also points out the sector division and controlling effects of the Shaqiuho-Korla fracture-break belt in the tectonic evolutions of Tianshan. This belt is deep fault whose nature is similar to that of the transform fault in the oceanic plate.
