Five pieces of paleogeographic maps were made out with modern stratigraphic principles and sedimantary system method. It is shown by the maps that in the beginning of the Changzhougou time the Yanshan Region was occupied by alluvial environment with paleoriver flowing northeast, in the middle of the Changzhougou time a transgression changed whole Yanshan Region into shoreline-shallow sea environment gradually, and sedimentary boundary extended so continuously that by the Gaoyuzhuang time it had overpassed far beyond the Yanshan Region.
在缺乏良好等时面的情况下,本文依据现代地层学原理和沉积体系分析法编制了常州沟组初期与中期,串岭沟组初期,大红峪组初期,及高于庄组初期燕山地区的岩相古地理图,示意了燕山地区在长城纪时由冲积扇-河流为主的陆地环境向滨海-浅海环境的演变过程,并揭示了沉积区域不断扩大的趋势,表明常州沟组初期,以蓟县-宽城为轴线发育了冲积相组,海岸线可能在燕山以北,常州沟组中期发生海侵,沉积区扩大至整个燕山地区,大红峪组时海盆范围继续扩大,高于庄组时,沉积边界已远远超出燕山地区。

Process and mechanism of electrodeposited Zn-Fe-Si02 composite coatings were studied, including some contents as follow: Potential-pH plots of Zn-H2O and Fe-H2O systems were drawn, and the thermomechanical analysis was made. Results showed that the region of zinc and iron's codeposition was wide, which provided theoretic basis for electrodepositing Zn-Fe alloy. But the balance potential of zinc was greatly different from iron's, so in order to make zinc and iron codepositing, some complexant must be added into electroplating solution.
本文研究了电沉积Zn-Fe-SiO_2复合镀层的工艺和机理,主要包括以下几个方面:绘制了Zn-H-2O系和Pe-H_2O系的电位-pH图,并对其进行了热力学分析,结果表明,锌和铁发生共沉积的区域很大,这就对电沉积Zn-Fe合金的可能性提供了理论依据,但是锌和铁的平衡电位差别较大,所以,必须在镀液中添入一定量的配合剂才能使锌铁产生共沉积。

The south-north united tectonic environment and tectonic pattern does not exist. The east-west trend thrusting Nappe structure of Majiatan and Hengshanpu can not represent the whole western margin of Ordos. The attempt to solve the regional tectonic problem with simple tectonic pattern is against the geological theory, especially in the Helan Mountain region.(2) After the geochemical data analysis of Ruqigou basalt in Helan Mountain, the article illustrates that it belongs to continental rift basalt which appeared in the late-Triassic and early middle Jurassic. Meanwhile the article states that the region is located in the rift environment of an extension background and Rudigou is located in the central part of the rift.(3) The article illustrates that the western ridge of Helan Mountain used to be on a slope and topography slowly declines from west to east after analysis and demonstrations of the distribution under XiaoSongshan bedding fault. Through comprehensive analysis of the no-strong deformation and bedding fault features, the article states that the Xiaosongshan bedding fault used to be gravity slip detachment structure and it represents the extension from the east to the west. Based on the above and analysis and demonstrations of isotope age and track datting, the article illustrates that the ? characteristic of the east of the western ridge of Helan mountain being higher than the west is the result of its late tectonic reverse.(4) Through comparison between Rujigou region Mesozoic Era late Triassic period-early and middle Jurassic period deposit and that of Ordos Basin and the analysis of the late Triassic period extension and early -middle Jurassic Period deposit povenevance it sets forth that during the period, Rujigou region was part of a large deposit basin which was closer to the northern povenevance and farther from the western povenevance.
以马家滩和横山堡为代表的东西向逆冲推覆构造模式,在整个鄂尔多斯盆地西缘不具有全区统一性,那种试图用单一的构造模式解决本区构造问题的尝试,无疑是与地质实际相悖的,尤其是对贺兰山地区;(2)通过对贺兰山汝箕沟玄武岩地质地球化学测试分析,提出其为大陆裂谷玄武岩,其形成时代为晚三叠—早中侏罗世,并通过该玄武岩的稀土和微量元素的测试分析资料进行了多种判别分析,最终确定该区处于拉张背景下的裂谷环境,汝箕沟地区大致处于当时裂谷的中心部位;(3)通过对小松山断层面之下地层分布规律,结合其变形特征的分析论证,认为当时贺兰山西麓处于一个由东向西平缓抬高的斜坡环境,并通过小松山断层面之下地层的非强烈变形及顺层断层特征等的综合分析,认为贺兰山西麓的小松山断层原本是一重力滑覆断层,它代表了近东西向的拉张,在此基础上通过裂变径迹测试资料的分析论证对其做了进一步认定,目前贺兰山西麓东高西低的剖面特征是该区后期构造反转的结果;(4)通过对汝箕沟地区中生代晚三叠世—早中侏罗世沉积与鄂尔多斯盆地内部的对比、晚三叠世延长组及早中侏罗世沉积物源和水流向分析,认为该时期汝箕沟地区为一更靠近北部物源,而距西部物源明显较远的沉积环境,是一更大型沉积盆地的一部分。
