Based on the theory of plate tectonics and the new knowledge of continental dynamics , this paper starts mostly with tectonic analysis and then makes a comprehensive view on the characteristic of stratum composition , gold mine mineralized , magmatic activity as well as ruptures activity to discuss the yanshanian tectonic evolution of the xiaoqinling area under the regional tectonic framework of qinling orogenic belt 本文以板块构造理论和大陆动力学研究的新认识为指导，采用以构造分析为主线，结合区内地层沉积、金矿成矿、岩浆活动以及南北两侧断陷盆地形成演化等综合分析，在秦岭区域构造大框架下对小秦岭燕山期的构造演化特征进行探讨。
The north - eastern structural zones which become intensity from the western part to the eastern one in gansu show a influence of marginal - west pacific indosinian - yanshan tectonic - magmatic belt on the western part of china ' s continent , and not only a important regional metallization had developed but also early - formed minerals were intense changed and enriched with the tectonic - magmatic activity 甘肃境内由西向东增强的北东向构造带，是我国东部滨西太平洋印支-燕山期构造岩浆活动带向大陆西部的延伸表现；伴随该期构造-岩浆活动，区内发生了重要的区域性成矿作用，并使处于该期构造活动带的先期金属矿产遭受了较强的叠加与再生改造。
On the basis of study on petrology , volcanic geology , geochemistry , isotopic chronology , antitheses of the regional strata and 4 suits of volcanic rock stratum of the yanshan - liaoning area , the rhythm of yanshanian volcanic activity is divided into 1 gigantic - cycle , 4 cycles , 11 micro - cycles , 24 sub - cycles and many rhythms . in addition , the temporal and spatial evolution and regional contrast of every - level rhythms are discussed . 3 . based on the study on classifications of rhythm of volcanic activity and regional contrast , the petrology , mineralogy , geochemistry , and isotopic characteristics of every - level rhythms are discussed 2 、通过对燕辽地区燕山期发育的四套火山岩的岩石学、火山地质学、地球化学、同位素年代学的综合研究，通过运用综合方法进行区域地层对比和分析火山喷发盆地火山岩地层特征的基础上，将本区燕山期火山活动节律，划分为1个二级节律(大旋回) 、 4个三级节律(旋回) 、 11个亚三级节律(小旋回) 、 24个四级节律(亚旋回)和多个五级节律(韵律)等，论述了各级火山活动节律特征及其时空演化和区域对比。
( 7 ) showing and determining the evidence and timing of the lithophere delamination occurred in qinling orogenic belt . pointing out the gold deposit in xiaoqinling - xiongershan region are mostly formed during indosinian to early - yanshan movement , related to mantle fluid injecting caused by lithosphere delamination and plutonic activity caused by further large - scale tectonic extension 初步阐述了东秦岭地区的成矿分区和成矿特点，指出小秦岭一熊耳山地区金矿形成的主要时期是印支一早燕山期，并且与岩石圈拆沉作用所引起的地慢流体活动和之后进一步大规模伸展作用产生的深源岩浆活动密切相关。
Through the analysis of subsidence history in the north of western ordos basin , as a result of the terranes northward accretion and the successive collision of the baykala block in the middle triassic , the qiangtang block in the late triassic , the lhasa block in the middle jurassic , the gangdese block in the cretaceous and the subduction of izanagi plate in yanshanian period , the studied region became a intracontinental foreland basin from late triassic to cretaceous 摘要通过对鄂尔多斯盆地西缘北段沉降史的分析可知，晚三叠世白垩纪，由于中三叠世巴颜喀拉地体、晚三叠世羌塘地体、中晚侏罗世拉萨地块、白垩纪冈底斯地体连续向北增生、碰撞以及燕山期伊佐奈岐板块的俯冲，盆地西缘北段的响应显示为陆内前陆盆地的特征。
When the tectonic system completely changed from paleo - asian tectonic circle to shore pacific tectonic circle , and established the elementary tectonic framework of shandong province . from then on , the tectonic movements of shandong were ascribed to the subduction ( north - west - trending ) of pacific plate under eurasian 燕山期( 205 65ma )山东地区地壳活动强烈，构造体系已由古亚洲构造域完全转化为滨太平洋构造域，构造活动导源于太平洋板块对欧亚板块的俯冲。
To make the yanshanian volcanic tempral and spatial distribution and evolution law clear , study the relationship of the deep crust - mantle processes and the volcanic rocks , the author selects the typical areas , xishan of beijing , duolun of inner mongolia , west liaoning , as the study areas where the volcanic rocks strata are developed . through the emphasised geological profiles of yanshanian volcanic strata being surveyed , much field work being done detailly , the small volcanic eruptive units have been defined originally , the levels of volcanic activity rhythm being constructed gradually , as a result , a integrated and systemic rhythm of yanshanian volcanic acivity has been constructed 为了揭示该区燕山期火山岩火山活动的时空分布与演化特征，探讨与深部壳幔过程的关系，选择了燕山期火山岩地层发育比典型的北京西山、内蒙多伦、冀北和部分辽西等地区，系统的测制了燕山期火山岩重点地层剖面，通过野外大量的详细观察，从建立最小的火山喷发单元开始，逐步地建立火山活动节律的级别，结合区域地层对比，建立了一个比较完整的燕山期火山活动节律及其级序。
It suggests that gold accumulation occurred in the every main stage of geologic history of fujian from late - archaean era to quaternary period but the scale and the feature of the gold accumulation are different in different stage and yanshan metallogenic epoch is the most important period of mineralization of fujian gold deposits 提出福建省内自晚太古代至第四纪的各个地质历史发展的主要阶段均有金的富集作用，但不同阶段所形成的金富集规模及特征明显有别，燕山期为福建省金矿最重要的成矿期。
Tncyclic diterpanes c20 , c21 and c23 distribution also has relationship with oil gravity , oil and gas production , as well as oil pool formation timing and oil source . rising - patterned oil originates from fengcheng formation , while peak - patterned oil from xiawuerhe formation . four types of migration and accumulation models are put forward : ( l ) fault controlled migration and accumulation along ridge far from source region ; ( 2 ) fault and unconformity controlled migration and accumulation around source region ; ( 3 ) fault controlled migration and accumulation in the slopes within source region ; ( 4 ) biogenetic and low temperature catalyzed gas migration and accumulation in middle and shallow formation 受挤压背景控制，研究区内海西期形成的断裂，全部为逆断裂，活动期长，可以延续到印支期和燕山期，断开层位可以从石炭系上延至诛罗系，它们对区域构造、沉积、油气运聚有显著的控制作用；而燕山期形成的断裂多为小型正断裂，部分为株罗系和白要系内部断裂，部分从徐罗系断至白圣系。
After current data analysis and field investigation , the authors consider that the xiangfan - guangji fault is a composite fault belt making up of various subgrade faults of different ages , including the early - stage ( indosinian - yanshanian ) southward thrust and late - stage ( himalayan ) northward thrust 摘要本文在系统总结现有资料的基础上，运用板块构造理论和现代造山带研究方法，通过野外工作，指出襄樊~广济断裂（带）是由多条不同时期断裂组成的复合断裂带，它包括早期（印支~燕山期）由北向南的逆冲构造和晚期（喜马拉雅期）由南向北的逆冲推构造。
