Results show that during the snowstorm disaster, under the large scale background with "trough in south and ridge in north", strong cold air caused by prevailing northerly wind in northern Asia wedged into low level atmosphere over Southeast China and formed a "clod cushion". At the same time, warm-wet air was also transported to Southeast China by southerly wind. The vertical shear of winds from cold to warm airflows produced strong upward motion and then, the warm-wet air over the cold air wedge was driven to rise. Finally, the structure of "warm cover" and "cold cushion", as well as corresponding vertical circulation over the converging frontal zone came into being.

研究结果表明，灾害发生期间，中国北方中低层大气盛行偏北气流，使较强的偏北冷空气"楔入"中国东南部低层大气，构成低层"冷垫"，同时偏南暖湿气流源源不断地将大量水汽输送到中国东南部，冷暖气流交汇及其垂直切变导致强烈的上升运动，构成了"冷垫"上空的"暖盖"及"南槽北脊"反位相环流汇合锋区的垂直环流结构。

在构造楔沿侏罗系西山窑组煤层向北扩展过程中，台阶状逆断层的大部分位移量沿构造楔顶部的反冲断层向南消减，另一部分位移量则沿西山窑组煤层向北传递至第二排背斜带，在总位移量保持稳定的前提下，第一排背斜带和第二排背斜带在走向上的此消彼长，反映位移量在南、北两个方向上的转换。

There are Hannan block in the northwest and Huangling block in the east. Its extended direction is east-northeast in the northwest area, east-west in the middle area and east-northeast in the southeast area,being a southwestward arc made up of many thrust nappes.

该带西北端受汉南地块限制，东部有黄陵地块的阻挡，其展布方向由西北部的北北东向、中部的近东西向、至东南部的北东东向，呈一向西南凸出的弧形，是由一系列呈向西南突出的巨型逆冲推覆断裂带构成。

Therefore, above-mentioned age dating together with previous chronologic data led us to conclude that the Sulu HP-UHP nappes have two basements: the Early-Middle Protrozoic (≥2400 Ma) basement in the N. Sulu and the Neoprotrozoic (700-800 Ma) basement in the S. Sulu. The basement ages in the N. Sulu together with its western part of the no-UHP metamorphic area (Laiyang-Penglai) are similar and named by the Jiao-Liao-Korea block belong to the NCP. Besides, the boundary between both of the S. Sulu UHP area and JLKB is along north Wulian and south Haiyangsuo.

北苏鲁超高压变质地区的花岗质片麻岩锆石SHRIMP U-Pb定年表明，变质基底的年龄是2400Ma（或＞2400Ma），并经历了1800～1700Ma和～200Ma的变质事件，研究表明苏鲁高压－超高压变质地体由2个不同时代变质基底组成，北苏鲁的变质基底属于北中国板块胶辽朝地块的一部分，形成时代比南苏鲁基底老得多，其与南苏鲁地块之间的界限位于五莲以北到海阳所以南一线。

The major deposits in the Sanzhou ore field are related to Yanshanian or later tectonic activity,which is divisible into six sequences represented by:1the Upper Triassic-Lower Jurassic low-angle normal slip fault and associated structures near or immediately occurring on the unconformity between the Lower Carboniferous and the Upper Triassic;2the longitudinally bucking fold in Devonian-Carboniferous and Upper Triassic-Lower Jurassic strata;3the earlier phase thrusts toward northwest;4the transcurrent fault toward northeast;5the later phase thrusts toward northwest;and 6the extensional normal slip minor faults.

彭少梅 ，杨坤光，姚淑梅三洲矿田内主要矿床与燕山期或更晚的构造活动有关。燕山期构造活动可分为六个序列：1下石炭统与上三叠统不整合面附近和不整合面之上的上三叠统―下侏罗统中的低角度正滑断层及伴生构造，2泥盆系―石炭系及上三叠统―下侏罗统中的纵弯褶皱，3北西向逆冲断层，4北东向平移断层，5第二次北西向逆冲断层，6伸展性正滑小断层。

Magnetic sus- ceptibility of these formations was obviously lower than the Archean high-graded metamorphic crystalline basements, while the responding ductile shear zones created enhanced anisotropy magnetic susceptibility attributed to their penetrative mineral lineations, both of them contributed to the crustal scale NEE-NNE striking linear aeromagnetic anomalies.

不同规模的古元古代活动带彼此并不相连，以发育变质沉积-火山岩建造为主体，岩石磁化率明显低于太古宙高级变质结晶基底，与之相关的韧性剪切带则以其透入性矿物线理产生了增强的磁化率各向异性，两者共同构建了地壳尺度北东东-北北东向线性航磁异常带。
