旋回

It seemed the south tectonic melange has only undergone the Hercynian — Indo-sinian ocean — continent transition from the sedimentary formation, but a few Caledonian syntectonic granites are found in the basement, which showed the Caledonian movement has also left some traces in this subzone.

从沉积建造反映的南部构造混杂岩带似乎只经历了海西期一印支期单旋回的洋陆转换，但在该构造带基底岩系中发育较多的加里东期同构造花岗岩类，说明加里东旋回的构造活动在该亚带也有较深的印迹。

Mineralized materials can be leached out from them by supergene water.and each types of ore deposits will be formed at different palaeogeography circumstances.

As KKД-500 gyratory crusher has large nip angle,linear steep crushing chamber profile,different throughputs of cross sections along the chamber height,it has poor crushing performance and short liner service life.Based on the structural analysis of the original crushing chamber,in the design principle of variable nip angle,the curve equations for moving cone lining and the fixed cone lining were setup by multi-stage fitted curves.

针对KKД-500旋回破碎机大啮角、直线陡锥破碎腔型，沿破碎腔高度各个截面的通过能力不尽相同，其破碎性能差，衬板使用寿命短的情况，在分析原旋回破碎腔型结构的基础上，按照变啮角设计原则，采用多段二次拟合曲线分别建立动锥衬板和定锥衬板曲线方程，利用计算机绘制衬板曲线，确定衬板结构，并优化破碎腔型。

SC1 cycle is dominated by longshore bar deposit, while SC2, SC3 by tidal hat system.

SC1旋回以滨岸砂坝沉积为主，而SC2、SC3旋回发育潮坪沉积体系。

The basin experienced three basin-forming cycles of Neopaleozoic, Mesozoic and Cenozoic Eras. Mesozoic fault and depression compounding basin composed the northern margin Jurassic petroleum system and the Cenozoic large-scale strike-slip and compressional basins composed the Tertiary petroleum system of the western Qaidam basin and Quaternary petroleum system of Sanhu. The intense tectogenesis of Yanshan and Xishan made the Jurassic petroleum system of the northern Qaidam more complex. The monocycle paleoclimate evolution in Cenozoic Era and multi-tectonic movement made the lake-basin evolution, hydrocarbon source-rock, reservoir development, accumulation condition and petroleum distribution are more exceptive in character and complex in feature.

该盆地经历了晚古生代、中生代和新生代3个成盆旋回，中生代断坳复合盆地形成了柴达木盆地北缘侏罗系油气系统，新生代大型走滑挤压盆地形成了柴达木盆地西部第三系油气系统和三湖第四系天然气系统，燕山和喜山2期强烈构造运动使柴北缘侏罗系油气系统高度复杂化，新生代单旋回古气候演化与多期构造运动使湖盆演化、烃源岩和沉积储层发育特征、成藏条件与油气分布规律变得十分特殊和复杂。

With the rich sediments supplied by the Pearl River, under the paleogeography sedimentary background of Baiyun Sag continuously subsiding, with sedimentary sequences related to relative transgressive sea level change ,contrary to regressive eustasy, the Pearl River Deepwater Fan System has specific evolution characteristics, which left the sedimentary record controlled by peripherical significant geological events. The sharp change of deposition rate and lithologic geochemical characteristics about 23.8Ma sequence boundary demonstratesd that sediment source had changed, perhaps related to the uplift of Tibet plateau and spreading of the South China Sea, which led the paleoPearl River drainage to expand to western China plateau , maybe much broader than present.

珠江深水扇系统以珠江为沉积物源、以持续深沉降的白云凹陷为沉积古地理背景、以与全球海退型海平面相反的相对海侵型海平面变化的沉积层序构成了其发育演化的特殊性，并留下了控制沉积的周边重要事件的记录。23.8 Ma等界面沉积速率和岩石地球化学特征均有突变，反映出物源区的变化，可能折射出与青藏高原隆升、南海扩张有关的重要事件，使得古珠江骤然向西部高原拓展，甚至较今天的珠江流域范围还广阔；承载珠江深水扇系统的白云凹陷持续沉降形成了陆坡内盆地，导致21~10.5 Ma BP多个层序深水扇垂向叠置充填的特殊沉积建造；根据60多口井资料建立的相对海平面变化曲线，具有与全球海平面变化相一致的三级旋回和不一致的二级旋回。
