| 摘 要： | 由于印支运动,大别造山带周缘各盆地物源不同,前期学者认为陆源碎屑岩主要来自扬子大陆。本文由大别山东南缘挂车镇剖面入手,通过对该地区侏罗纪碎屑岩进行地球化学分析,并结合判别图投点分析。研究区碎屑岩是经过短距离搬运、快速堆积形成,物源地应为北面大别山地区,该盆地为前陆盆地。

| Abstract: | As a result of the Indosinian movement, basins around the Dabie orogen have different sources of material. Early scholars thought that terrigenous clastic rock is mainly sourced from the Yangtze Continent. This paper, starting with the Guachezhen profile at the southeastern fringe of the Dabie Mountain, performed geochemical analysis of the Jurassic clastic rock in the area, combined with analysis of projective points of discrimination diagram, concluded that the clastic rock has been subject to short-range transport and fast accumulation, the source should be the Dabie Mountain area to the north, and the basin is foreland basin. |
