摘要
通过 1∶2 5万区域地质调查和三叠系专项研究 ,在义敦岛弧带的四川省新龙县雄龙西、白玉县热加获得一批植物化石 ,计 15属 2 0种 ,其中包括两个新种 ,一个属种为国内首次发现。这些化石不仅丰富了本区植物化石组合内容 ,而且对地层时代的确定及与邻区的对比和沉积环境的恢复提供了重要的古生物依据。
During 1∶250 000 regional geological surveys and special subject research on the Triassic, a group of plant fossils were taken from Xionglongxi, Xinlong County, and Rejia, Baiyu County, Sichuan Province. They include 15 genera and 20 species, of which two species are new and one genus was first found in China. These fossils not only enrich the content of the plant fossil assemblage in the study area but also provide an important paleontological basis for the determination of stratigraphic ages, stratigraphic correlation with neighboring areas and reconstruction of the sedimentary environment.
