Based on the analysis on the oil sources and migration pathway of this area, the mineralization modes of the oil sand in the area are derived in this paper. Main conclusions are drawn as follows: a. multiphase tectonic activity resulted in multistage hydrocarbon generation of the source rock; b. threestage tectonic activity and threestage mineralization process formed a great deal of unconformity and fault pathway, thus the crude oil could migrate in a long distance; c. the tectonic activity in Yanshan and Himalayan stages uplifted the edge of the basin and the eroded reservoir outcropped to the surface, the light oil escaped and then the oil sand resource formed; d.

Combining the actual rockburst status after excavation, based on the previous research data in the earlier stage, the character of the tectonic stress in Cangling Tunnel is studied. Finite element method is adopted to simulate the site excavation steps. At the same time, the tectonic stress is changed on the boundary of the model to simulate the actual rockburst areas; and the most proximal area's value is adopted to decide the section tectonic stress. Then, other sections' values are revised.

从苍岭隧道的构造应力场特征入手，结合现场开挖后岩爆实际发生状况，在前期研究资料的基础上，利用有限元计算分析，模拟现场实际施工步骤的同时不断改变模型边界上的构造应力来拟合实际岩爆区，以最接近实际破坏范围的计算结果界定区段构造应力值，据此对隧道各区段的构造应力进行修正。

The orogenic strata have following characteristics: During the subduction and intracontinental orogeny, the strata experienced dramatic tectonic migration and mixing, resulting in various tectonic features. A short sequence usually composed of tectonic slices of various origins, times, deformations and metamorphisms, and scales. The original sequence was badly destroyed. The extant fragments of orogenic belt usually took form as melanges, especially the accretion complex wedge generated in subduction zone, which is contrary to the Law of Superposition. The original location of the accretion is also contradicted with the Law of Original Horizonality, because the accretion is oblique with high degree. Marine rocks, volcanic rocks of continental margin and metamorphic rocks were well-developed in the orogenic belt, especially ultra-basic, basic rocks were wide spread and were intensely metamorphosed, accompanied by metamorphic slices returned from hundred kilometers underground with ultra-high pressure and magma movements during syn-orogeny and post-orogeny, thus formed the colorful landscapes.

Tectonic analysis of Pre-Carboniferous metamorphic stratum and structural foliation dating have shown that The Qinling and its vicinities had happened an important regional tectonic event -Caledonian event, this event represents early paleozoic closure of the Qinling ocean basin and continent-continent obliquely diachronous collision, so we also could reconstruct Caledonian Qinling orogenic belt's basic tectonic framework.

对北秦岭地区前石炭纪变沉积—火山岩地层系统进行构造解析，以及构造面理定年数据表明，秦岭及邻区志留纪至早泥盆世经历了区域性的重大构造事件，相当于加里东事件，该事件代表了秦岭早古生代洋盆闭合、陆—陆碰撞造山的造山事件，并可恢复加里东古造山带的基本构造格局。

The multiphase tectonic activities above clearly controlled the move and gather of salifying brine, the strongth of salt-forming and the deposition of salt-bearing strata. With the pass of time, the salt-bearing strata thickened gradually from northwest to east and southeast, and the distribution of the thickness trended towards complicated; the measurement of the halite deposition extended towards east too; in the early Palaeogene and the Neogene, strong multiphase tectonic activity was a disadvantage to salt-forming, but in the middle and late Palaeogene, weak multiphase tectonic activity, which resulted in slow and sustained subsidence of the basin, was greatly advantaged to it, especially to potash-forming.

古近纪和新近纪成盐卤水的迁移和聚集、成盐作用的强弱以及整个含盐系的沉积发育明显受到上述构造活动的控制：含盐系的厚度随时间由北西向东、向南逐渐增厚，且厚度分布逐渐趋于复杂化；石盐岩的沉积规模和范围也逐渐向东扩大；古近纪早期和新近纪强烈的构造活动对于成盐作用而言是一种干扰因素，而古近纪中、晚期相对较弱、导致盆地缓慢持续沉降的构造活动对成盐，尤其对成钾作用则极为有利。

The Sm-Nd isotopic results indicate that the Archean tectonic regime and crust growth in Northern China Platform can be divided into two stages.

Sm－Nd同位素研究结果显示，华北地台太古宙构造体制与地壳生长可分为二个发展阶段：2800Ma以前，地壳以幔源物质垂向增生为主；进入2800Ma以后，地壳物质开始进入地幔，并以水平运动为主要构造体制，反映板块构造机制在太古宙晚期地质演化中具有十分重要的作用。

Also being with the metamorphic crystalline basement formed later and suffered the stronger tectonic event and the material composition reforming, being composed of the material with low density and existing the relatively weak intrinsic mechanical system, Huaxia massif was affected by the various tectonic movement in the later period, the layers inside the lithosphere interacted under action of the tectonic force, this led to the material composition and the structure regulated and changed constantly by the magmatism in the crust, underplating and faulting and folding, therefore, the ability to resist the deformation decreased with the every variation.

华夏地块变质结晶基底形成时代晚，并遭受更多更强构造变动与物质组分的改造使之物质组成密度较小，岩石圈先期固有的力学结构系统相对较弱，尤其是后期的地球大系统的历次构造运动都对其施加影响，构造动力作用下引起内部圈层间相互发生作用，导致内部物质成分、结构形态通过壳内岩浆活动、地幔底侵作用、断裂褶皱等不断的调整重组重建而变化，其每一次调整变化，都使其总体抵抗变形能力进一步降低。
