Opening and closing are two basic geological movements, which may result in a series of structures. The highest level of opening is the appearance of oceans and the highest level of closing is the consolidation of continents. Based on field investigations, the authors consider that identifying the marks of opening-closing tectonics is the basis of the issue and classifying the types of opening-closing tectonics is the key of the issue. This paper briefly discusses the substance and the future of the study on the opening-closing tecton cs in China. The authors hope to share relevant information with geoscientists in the world in this field.展开更多

The junction relationship between Ganjiang and Tanlu faults is analyzed in this paper, and this has been elucidated through numerical simulation about the tectonic stress field analysis. Numerical simulation of the tectonic stress field conducted for the major mineralization stage of the Jiujiang-Ruichang junction area reveals that the stress field of the junction structure at the major mineralization stage shows a relatively close relationship with the formation of the ore deposits (occurrences).展开更多

文摘The opening-closing tectonics theory, a theory about opening-closing tectonics, is a viewpoint regarding geotectonics suggested by a group of Chinese scientists. Opening and closing are two basic geological movements, which may result in a series of structures. The highest level of opening is the appearance of oceans and the highest level of closing is the consolidation of continents. Based on field investigations, the authors consider that identifying the marks of opening-closing tectonics is the basis of the issue and classifying the types of opening-closing tectonics is the key of the issue.
