Research advances in the Mesozoic tectonic regimes during the formation of Jiaodong ore cluster area 总被引:33,自引:0,他引:33

Based on research advances of the tectonic regime in Jiaodong ore cluster area and the related tectonic regime transformation in Mesozoic era in the eastern region of North China, in this paper, we first summarize some key problems required to be studied further on. Then we suggest an approach to dealing with these problems. It is known that the gold deposits in Jiaodong ore cluster area, which are of different mineralization styles, spatial distributions and geological settings, might be as a result from one or more geologic events in Mesozoic. Till now, this kind of research on the temporal evolution and spatial migration sequence, especially on the geodynamic mechanism of the above events, is far from sufficient. Moreover, quantitatively describing the action mode and the temporal?spatial framework of tectonic dynamic regimes and formulating the relative contribution of every tectonic dynamic regime for the metallogensis are still challenges to the geologists studying on the formation of Jiaodong ore cluster area. According to the interpretation of the regional tectonic analysis, the structural dynamics, the observation and the exploration of the mineralization network, we propose a geological?physical?chemical model with some constraints originated from the comprehensive analysis. We then use this model to simulate the coupled processes of the structural deformation, thermal transport, fluid flow and the chemical reaction. The obtained results indicate that the model is efficient in further analyzing the temporal?spatial evolutional trail of the tectonic regime in Jiaodong ore cluster area and in further understanding the nature of the mass metallogensis. 相似文献

基督教与近代西方文化在朝鲜半岛的传播 总被引:1,自引:0,他引:1
刘丹 《贵州师范大学学报(社会科学版)》2000,(1):56-59
文化传播是人类历史发展的重要内容,而宗教传播又是文化传播最重要的途径之一,基督教与西方文化的这一关系在近代朝鲜半岛表现得非常明显:首先是近代早期朝鲜的知识分子被以基督教为中心的西方文化所吸引,使基督教得以在朝鲜半岛扎根,并使西方文化在这里进一步传播。继而是19世纪后半期开港以后,西方传教士的不断到来,使基督教和西方文化在朝鲜半岛以更大规模传播,并在朝鲜半岛的近代教育和文化“启蒙”运动中起到了重要作用。 相似文献

Gold deposits are characterized by multi-sources, superimposition, large scale and temporal-spatial concentration in Jiaodong Peninsula, Eastern China. In this paper, we review the history and the development of the study on metallogenic chronology and genesis of gold deposits, summarize the main features of superimposed metallogenesis, provide evidence of the Mesozoic complex metallogenic system, and point out some problems for further research of Jiaodong gold deposit cluster from a regional view. Although gold deposits are different in genetic types, ore-forming materials and geological settings, our research indicates that the accumulation and emplacement of the ore-forming materials are temporally-spatially concentrated on a large scale, and the main metallogenic epoch of Jiaodong gold deposits was concentrated in Mesozoic. Metallogenic chronology and geological-geochemical data indicate that there are two periods of gold mineralizations occurred in 130?110 Ma and 90?80 Ma respectively in Jiaodong ore cluster. The gold deposit cluster results from the superimposition of the polygenetic mineralization, and further study is needed to investigate the formation and evolution of the Mesozoic complex metallogenic system. 相似文献
