Neo-tectonic movements in the northern section of the Yuanmou fault zone, Yunnan Prov. are very well reflected by the modification of landforms and the deformation of the early Pleistocene lacustrine strata.1. A narrow, deep trough-basin (the Yuanmou Basin) formed on the western side of the major Yuanmou fault was at first filled with Q1 lacustrine deposits of more than 400m thick, and then uplifted into a westward tilting high lake terrace. Subsequently 5 lower and lower river terraces appeared one after another only along the eastern margin of the trough-basin. The Longchuanjiang River, which has carved out the terraces, now runs along the western margin of the basin.2. Jurassic sandstones and shales were thrust westward on Q1 lacustrine deposits, which was affected by a series of young folds and faults. These folds and faults trend with a sharp angle toward the major Yuanmou fault and constitute some Quaternary tectonic structures of "A" pattern.3. A series of cross tectonic structures such as downwarp-faulted basins with an arched uplift between them is found in the trough-basin.All the features above mentioned suggest that the northern section of the Yuanmou fault zone forming the middle part of the Sichuan-Yunnan N-S tectonoseismic belt, has been affected not only by vertical, but also horizontal (either sinistral or dextral) multi-cyclic movements.Nevertheless, from the seismo-geological analysis we consider that the risk of a destructive earthquake here would not be so serious as that in the northern and southern terminal areas of the Sichuan-Yunnan N-S tectonoseismic belt.

The South-to-north water transfer is a magnificent project in China, which brings excess water from the Yangtze River in the south to the arid areas of North and Northwest China. The proposed East Transfer Route would pass through and supply water to the Huang-Huai-Hai plain,The liuang-Huai-Hai plain is a weakly or easily salinized region . Owing to the influence of the pacific monsoon, this region has always been suffered from disasters of drought, flooding, salinization and alkalization throughout the history. Under this specific natural condition and human activity , sail salt-water movement is significantly characterized by seasonal changes. Soil is in the process of modern salinization,only varying in degrees of salt accumulation with location and times. Therefore, in the design and implement of the South-to-north Water Transfer, attention should be paid to the control of soil salinization .Alter the water is transferrer, the irrigation area in the Huang-Huai-Hai plain will be enlarged. There will be a beneficial effect on improving water condition of this region, leaching soil salt and promoting agricultural production. At the same time, the present salt-water balance of the region will be changed. The districts with poor natural drainage and without artifical drainge system might be confronted with secondary soil salinization.If the four lakes in the south of the Huang-He are used as regulation reservoirs in the South-to north Water Transfer project, then the elevation of the original storage level of the lakes will have a definite effect on the drainage of the main channels in the west of the four lakes and on soil salinization.From a long-term point of view, it is necesary to dig deep trough or to deepen the bottom of the lakes to meet the requirment of storage capacity and storage level of the lakes. In addition, the channel of drainage flooding and controlling seepage should be excavated along the west side of the four lakes, to reduce and control groundwater level of the region along the lakes, at the same time, pumping drainage station should be established at the outlet of the main drainage channel, to settle drainage outlet and increase capacity of drainage flooding.The conveyance of water for a long period of time in the main canals, especially in the stretches where the level of transported water is higher than the land surface, would lead to the formation of high-water-table zones on both sides of the canals, owing to a large amount of seepage of canals. The groundwater runoff in the left side of the main canals would impede in varying degrees and block the drainage of underground runoff and might lead to a general increase of the level of groundwater and aggravate soil salinization along the canal. Both an adequate engineering drainage system of controlling or intercepting seepage and an agricultural technique should be considered. At the same time, a scientific management system for the supply of transferred water should be worked out. So long as more attention is paid and appropriate and reasonable measures of water management, agricultural and engineering system are adopted, soil salinization could be prevented or controlled.

A deep trough which was more than 700 km long stretched from north tosouth in west Yunnan in the Devonian.Submarine fan of terrigenous debrisand the related deep water sediments were well developed there,thus formed theassemblage of both submarine fan model and carbonat slope wedge model.The fan is between high energy system and low energy system,but moreclose to high energy system.It can be divided into five subfacies such asinnerfan facies,central-fan facies,outer-fan facies,fan marginal facies andbasin-plain facies.The carbonate sediments on base of the slope along the dis-tribution of carbonate slope,as a self-formed system,are not controlled by thefan body.It consist of allochthonous sediments in carbonate gravity flow andautochthonous sediments in deep water.The provenance of the former is relat-ed to the submarine canyon which deeply cuts the slope,and that of the fateris the adjacent carbonate platform.Gravity sediment,especially the submarine fan show up distinct phases.Itcan be divided into embryonic stage(Shanjiang-Alengchu period,i.e.,the earlystage of the Early Devonian),prime stage(Banmandaodi period,i.e.,the latestage of the Early Devonian)and depauperation stage(the Middle Devonian).They constitute the evolution history of deep water sediments.

滇西泥盆纪时存在一南北向深海槽,长达700km 以上,其中发育陆源碎屑海底扇及与之相关的深水沉积,构成海底扇模式与碳酸盐斜坡楔状体模式的组合实例。海底扇居于高效能与低效能类型之间,更偏于高效能体系,物质来源与深切斜坡的海底峡谷有关。坡脚碳酸盐沉积自成体系,不受扇体控制,沿碳酸盐斜坡分布,由异地碳酸盐重力沉积与深水原地沉积组成,物质来自邻近的碳酸盐台地。重力沉积,特别是海底扇沉积,阶段性甚明显,可划分出萌动期(江(?)阿冷初期,即早泥盆世早期);全盛期(班满到地期,即早泥盆世晚期);收缩期(中泥盆世)。
