为了提高石油和天然气的勘探、开发效率,为古三角洲的研究提供对比模式和识别标志,1973年以来,我们对长江三角洲进行了比较系统的研究,取得了一些初步认识,现简要报道于下。 长江源远流长,水量丰富,是我国第一大河。晚冰期低海面时,它出宁镇山脉后,继续东流,横穿现代东海大陆架,直至大陆架边缘人海.晚冰期后,随着世界海面的上升,河口逐渐后
In order to improve the exploration and development efficiency of oil and natural gas, and to provide comparative patterns and identification marks for the study of the ancient delta, we have conducted a systematic study of the Yangtze River Delta since 1973, and made some preliminary understandings. Yangtze River has a long history, rich in water, is China’s largest river. After the low glaciation in the late glacial period, after it came out of the Ningxia mountains, it continued to flow eastward across the continental shelf of the modern East China Sea until the edge of the continental shelf.
