构造沉降 meaning in Chinese
tectonic descent
tectonic subsidence
Examples
- The formation and evolution of the sequence stratigraphy of the yanchang formation are governed by slow tectonic subsidence , warm humid climates , sediment supply and lake - level fluctuations
延长组层序地层的形成与演化主要受控于当时缓慢的构造沉降、温湿气候、陆源碎屑物源供给及湖平面升降等地质因素。 - One of the frontier recearch of basin analysis in recent years is to analyze the tectonic subsidence history of depositional basins which occur in orogens at different geohistory stage , and to discuss the geodynamic processes involved with the basins
摘要对造山带各地史阶段的沉积盆地进行构造沉降分析，进而探讨其地球动力学过程，是近年来盆地分析的前缘研究之一。 - By using the standard deviation method , the scaling properties described by the local fractal dimension d and crossover length tc of 48 measured landform profiles in different direction of 6 different studied landform sections are calculated
负反馈机制表现的越明显；对于以构造沉降作用为主的盆地区而言，各个方向的地形剖线的分维值均显示出小于1 . 5的正反馈机制。 - Yanchang 4 + 5 sector to yanchang 3 sector lithofacies palaeogeography pattern was stable , because the constitution background was steady , and the source direction had no change , and supply was abundant . in those sectors the basin development was in lake retreat , and in the period of extinction gradually , and formatted construction delta deposit , but in yanchang 33 period the sedimentary speed were greater than construction speed , showing that overriding river mouth bars were abundant
长4 + 5 ?长3期湖盆发展处于湖退、萎缩逐渐消亡时期，由于构造背景稳定，物源来源方向没有变化，物源供给充分，所以岩相古地理格局基本一致，形成建设性三角洲沉积，但长3 ~ 3期沉积速率大于构造沉降速率，表现为叠置河口砂坝极其发育。 - The tectonic subsidence curves on the southeastern margin of the yangtze plate are drawn out using of backstripping method for the basin formation and evolution . the basins located in the southern margin of the yangtze plate , in the basin dynamic computer simulation , is explored and constituted to be a typical foreland basin which is of not rather high mountain and thermal situation to be lower in this older orogeny belt
在沉积盆地分析方面，基本查明扬子板块东南边缘早古生代被动大陆边缘沉积特征及沉积构造演化，同时运用反剥法技术对扬子板块东南大陆边缘沉积盆地形成，演化的构造沉降动力学进行探讨，运用计算机模拟方法，定量动力沉积学对扬子东南边缘奥陶纪到志留纪前陆地进行计算机模拟分析，探索并建立这个古老造山带前陆盆定量参数和动态定量模拟。
