近几年来,我国沉积相和古地理研究工作有了较大发展。从五十年代和六十年代的以小比例尺乃至概略性的沉积相和古地理编图,已经发展到目前以大、中比例尺为主的沉积相和古地理研究。推广了利用碎屑岩结构概念来研究碳酸盐岩的新观点;吸取了许多国外沉积模式研究的新成果;水槽试验的新资料也在沉积相和古地理研究中得到了应用等使沉积相和古地
In recent years, China’s sedimentary facies and palaeogeography research has made great progress. From the small-scale and even sketchy maps of paleogeography in the 1950s and 1960s, sedimentary facies and paleogeographic studies dominated by large and medium scales have been developed. The new viewpoint of using the concept of clastic structure to study carbonate rock was popularized. Many new achievements in sedimentary model research abroad were obtained. The new data of the flume experiment was also applied in sedimentary facies and palaeogeography. And ancient land
