Basin Analysis
Subsidence analysis utilizing decompaction of a sedimentary sequence permits the discrimination between externally driven tectonic subsidence and subsidence induced by isostatic response to the weight of the accumulating sedimentary column (Steckler and Watts, 1978). Given the absence of published well-log stratigraphy in the southwest Tarim basin, outcrop data provide the only database for analyzing basin subsidence. Backstripping was performed with the Macintosh program, Basinworks, which is based on the methods of Van Hinte (1978) and Steckler and Watts (1978).
Subsidence analysis was performed on four measured sections, Kuzigongsu,Wenguri,Wuyitake,
and Aertashi, extending from Jurassic or Cretaceous through Paleogene or Miocene in age (Fig. 11). Neogene strata at three of the measured sections contain unconformities,whereas at the fourth,Wenguri, the Miocene section terminates in the core of a syncline. In addition, the surface uplift history between Oligocene marine deposits and the present ~1200 m elevation of the outcrop belt is poorly constrained. Therefore, the subsidence analysis presented here is truncated at the top of the continuous Cenozoic stratigraphic section.
The tectonically driven subsidence curve of the thickest section, Kuzigongsu, has a concaveupward shape beginning in the basal Jurassic strata. This shape resembles an exponentially decaying thermal subsidence curve, suggesting that extension or transtension and thermally controlled subsidence began in Early Jurassic or Late Triassic time (Steckler and Watts, 1978; Christie-Blick and Biddle, 1985). For the remaining three sections, the subsidence rate was roughly constant and fairly low until middle Tertiary time. Although thick conglomerates were deposited at Kuzigongsu and Wuyitake during Late Jurassic to Early Cretaceous time, they are not reflected in the subsidence curves. However, the limited resolution of existing biostratigraphic data cannot resolve variations in sedimentation rate during this interval.

盆地分析的基础上,
沉降分析decompaction沉积序列的外部驱动之间的歧视和沉降的构造沉降isostatic反应引起的重量(Steckler积累沉积,1978年),美国瓦茨。没有发表了西南层测井数据为塔里木盆地、露头的唯一数据库来分析盆地沉降。Backstripping苹果机的程序,Basinworks,是基于方法Hinte(1978),范Steckler和瓦(1978)。
沉降量进行了分析,Kuzigongsu四,Wenguri,Wuyitake,
和Aertashi,延伸至侏罗纪和白垩纪通过在年龄范围或中新世(图)。在新近纪地层中的三个部分包含顶测,而在第四节Wenguri终止,中新世东的核心。此外,表面隆起之间的历史,目前渐新世海相沉积~ 1200米高程较差的露头带约束的。因此,分析了沉降截断在顶部的连续新生代地层区。
这个构造沉降曲线驱动,Kuzigongsu最厚的部分,有concaveupward形状的基底侏罗系地层的开端。这种形状就像一个指数衰减热沉降曲线,暗示或transtension和热力控制型沉降始于早侏罗世或晚三叠世的时间(Steckler和瓦的能量,同样的,依据;Christie-Blick 1978年,1985)。对于其余的三部分,沉降速率是不变的,直到第三时间相当低的中间。虽然被存入Kuzigongsu厚集团和Wuyitake早白垩世晚期侏罗纪期间,他们不是体现在沉降曲线。然而,有限的决议biostratigraphic数据不能解决存在差异沉降速率在这段期间。

盆地分析
沉降分析利用一个沉积序列decompaction许可证之间的外部驱动的构造沉降和均衡响应累积沉积柱(施特克勒和Watts,1978)的重量引起的地面沉降的歧视。鉴于刊登在塔里木盆地西南测井地层的情况下,露头数据分析提供了盆地沉降唯一数据库。剥是与Macintosh执行程序,Basinworks,这是对凡欣特(1978)和施特克勒和Watts(1978)方法的基础。
塌陷分析是衡量四个部分,Kuzigongsu,Wenguri,Wuyitake,
和Aertashi,延长侏罗纪或白垩纪第三纪或通过年龄中新世(图11)。在实测部分包含三个新近系地层不整合面,在第四,Wenguri,中新世节而终止于一个向斜核心。此外,渐新世之间的海相沉积和本〜1200米的海拔露头表面隆起带的历史是不好的制约。因此,这里提出的沉降分析被截断在连续的新生代地层剖面顶部。
最厚部分的构造沉降曲线驱动,Kuzigongsu,已形成一个concaveupward侏罗纪地层中的基础开始。这个形状类似于一个热沉降曲线呈指数衰减,表明延期或transtension和热沉降控制在早侏罗纪或晚三叠世时(施特克勒和Watts,1978;克里斯蒂-布利克和比德尔,1985年)开始。至于其余三个部分,沉降速率大致不变,相当低的,直到第三纪中期的时间。虽然厚砾岩沉积于晚侏罗世在Kuzigongsu和Wuyitake早白垩世时,他们都没有反映在沉降曲线。然而,现有生物地层数据有限决议解决沉淀不能在这个区间的变化率。
