This study used some techniques such as organic geochemistry bulk composition combined with molecular geochemistry , source rock analysis and evaluation of organic petrology , carbon isotopes of organic matter , petroleum geology inference etc . the emphasis is mainly concentrated on the source rocks belong to the shahejie formation of pal eocene , including the source rock evaluation of denan region , geochemistry of the source rock , biomarkers of immature oils and source rocks . then the ancient geological environment was established and immature oil formation mechanism was proposed . following results have been tentatively proposed in this thesis : 1 ) based on the organic petrology studies , most of source rocks in this region is belong to immature source rock 本项研究以德南洼陷重点烃源岩- - -下第三系沙河街组为对象，应用有机地球化学理论与方法对其有机质类型和丰度、成熟度、生烃潜量等进行研究；通过特征生物标志化合物的分析，阐明研究区未熟-低熟烃源岩母质构成、沉积环境和成熟演化；通过油源对比和生烃条件综合分析，提出本区烃源岩生烃机制，建立未熟-低熟烃源岩有机质生烃模式。
Geologists and geophysicists have carried out substantial work on petrology , geochemistry , chronology and geophysics , et al . , which yields important reference material and constrains for explanations of questions , such as the delamination and exhumation mechanism for the lower crust , models of the rapid uplift of himalayan orogen and deep subduction of india - eurasia plate . while only a little has been done to study the eastern syntaxis at present 地质学家和地球物理学家已经对西构造结进行了大量的岩石学、地球化学、年代学和地球物理学等方面的研究，为解释下地壳的拆沉、折返机制，喜马拉雅造山带的快速隆升和印度-欧亚板块的大陆深俯冲模式等提供了重要的参考信息和约束条件。
This research focuses on the sedimentology , basin analysis and tectonic evolution of mesozoic strata in the north margin of the dabie orogenic belt , using an integrated approach of modern sedimentology , continental dynamics , petrology , geochemistry and isotope chronology . the topics of the study include : ( 1 ) 以现代沉积学和大陆动力学理论为指导，结合岩石学、地球化学、同位素年代学等诸多学科，对大别山造山带北缘地区中生代地层进行沉积学、盆地分析以及构造演化研究。
The goals of the thesis are mainly to investigate the structural profile at baila village in indus - tsangpo suture zone , and to provide us with effective reference information about deformation history of indus - tsangpo suture zone based on studies on petrology and petrofabric analysis of quartz in addition to detailed field observations 针对上述问题，本文进行了以下研究：本文以雅鲁藏布江结合带内部的“白拉村结合带构造剖面”为重点研究对象，在野外详细观测的基础上，通过室内岩石学研究和石英组构分析，为雅鲁藏布江结合带的变形历史提供了有效的参考信息。
Against the particularity of problem of gas bursting of ( subscript 1 ) coal seam in ludian gliding structure in west henan , through a large amount of work of field surveys and interior research , and viewed from the basic theories of structural petrology , discussed some characteristics of mining gas hazard such as image , mechanism and tectonic control process 摘要针对豫西芦店滑动构造区二(下标1 )煤层瓦斯突出问题的特殊性，通过大量野外地质调查和室内研究工作，从构造岩石学基本理论着手，讨论了构造区矿井瓦斯地质灾害的表象、机理和构造控制作用。
On the basis of the study on the petrology , trace element , and isotopic geochemistry , the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting . one is the basanite - alkaline basalt - olivine tholeiite magma series , which are generated by partial melting from spinel iherzolite ; the other is nephelinite magma - alkaline picritic basalt magma , which are generated by partial melting of the garnet iherzolite 岩石化学、微量元素、同位素地球化学证据都表明，华北、华南地区的火山岩根据源岩和局部熔融程度的不同，可以分为两个原生岩浆系列：一个是源岩为尖晶石二辉橄榄岩，随着局部熔融程度的增加，形成的碧玄岩岩浆-碱性玄武岩岩浆-橄榄拉斑玄武岩岩浆；另一个是源岩为石榴石二辉橄榄岩，随着局部熔融程度的增加形成的霞石岩岩浆-碱性苦橄玄武岩系列。
