Migration of the Late Triassic-Jurassic depocenter and paleocurrent direction in the Dabashan foreland basin
大巴山前陆盆地晚三叠世—侏罗纪沉积中心的迁移及古流向
From the angle of recovering palaeogeomorphology, according to the theory of impression way of remnant thickness and bucking thickness, the thickness of early Late Triassic paleo-formation is recovered and depocenter is confirmed.
从古地貌恢复的角度出发,依据残留厚度和补偿厚度印模法原理,恢复了鄂尔多斯盆地晚三叠世早期古地层厚度,从而确定了沉降中心;选取粒度矩法平均值这一参数,对同井位同层位的粒度值求平均值,将所得值投放平面图,获得粒度均值平面等值线图,湖盆中细粒碎屑物质的聚集区反映了古水流的汇合区,指示沉积中心。
Comprehensive research on the structure attributions,the primary basin features,the combination of lithology and lithofacies,provenance analysis,and the distinction of thickness distribution of the Ordos Basin in the Mesozoic,suggests that the depocenters of the basin transferred contraclockwise from southeast to north,then to southwest from middle Late Triassic to Early Cretaceous.
通过对鄂尔多斯盆地中生代构造属性、原盆面貌、岩性岩相组合、物源分析和厚度分布特征等的综合研究表明,从中晚三叠世至早白垩世,盆地沉积中心由东南向北、再向西南发生逆时针迁移;在盆地西部,早白垩世沉积前没有统一或规模较大的堆积中心,仅存在孤零分布或彼此分割、规模不大的局部堆积中心。
A hiatus is the total interval of geologic time.
一个沉积间断是地质时间的总间隔。
The hiatus in sedimentation is filled in progressively from below.
沉积间断面是从下边逐渐填满的。
Such truncation is evidence of an erosional hiatus.
这种削蚀现象是侵蚀沉积间断的证据。
Sedimentation ceases: tilling or folding is accompanied or followed by uplift.
沉积间断，即掀斜或褶皱伴生或伴随着抬升运动。

locate in fault basin or sediment basin among plateaus,have deep and great rupture developing and controlling;
均处断陷盆地或高原山间沉积盆地,有深大断裂发育控制;
The major cause leading to such a distribution pattern is that the sedimentary facies in this district was controlled by the foundation faults formed in Caledonian orogeny.
构成这一特殊沉积格局的主要原因是该区沉积相受加里东运动期间形成的基底断裂控制。

The region was subsequently inundated by a shallow sea. Sediments laid down during this time are represented by the Carboniferous marble of Yuen Long and Ma On Shan.
该地区其后遭浅海淹没，期间沉积物不断积聚，元朗和马鞍山的石炭纪大理岩，便是该时期的产物。
