摘要: 通过对金沙江雅砻江河口-金坪子段的地貌、沉积和年代学的研究, 结合区域地貌和新生代沉积, 初步认为该区域河流发育经历了4个阶段:高原面解体河流发育期(7～4.2Ma)、高原湖泊和盆地形成期(4.2～1.1 Ma)、古雅砻江和古金沙江期(1.1～0.73 Ma)和金沙江贯通东流期(0.73 Ma至今)。7～4.2Ma, 高原面解体发育河流, 攀枝花地区河流形成两级陡坎, 并形成昔格达组下伏的卵石层; 古鲹鱼河开始发育形成, 可能越过现代金沙江的位置进入古掌鸠河, 汇合到昆明盆地。4.2～1.1 Ma, 昔格达组、会理、会东盆地均发育; 古城河可能流入元谋盆地; 攀西地区的湖泊和元谋的湖泊可能不相连; 古鲹鱼河在1.1Ma前改道东流, 并未贯通为金沙江。1.1～0.73 Ma, 古鲹鱼河贯通为金沙江, 不断地向古城河方向溯源侵蚀; 古雅砻江和古城河入元谋盆地; 0.73 Ma, 金沙江袭夺古城河、古雅砻江而贯通, 元谋组堆积结束。0.73 Ma以来, 金沙江快速深切; 中晚更新世开始发育阶地。Abstract: Based on the study of the fluvial geomorphology along the Jinsha river from the estuary of Yalongjiang to Jinpingzi by using the methods of sedimentology, geomorphology and chronology, combining with the character of geomorphology and the Cenozoic sediment in this region, we suggest that the development of reach can be divided into four stages, i.e, 1) the river developing on the plateau (7-4.2 Ma), 2) the lake and basin developing on plateau (4.2-1.1 Ma), 3) the ancient water system developing (1.1-0.73 Ma), and 4) the eastward flowing of Jinsha river (0.73 Ma). 7-4.2 Ma, the river developed after planation surface discomposed.The two steep slopes of 1800-2000 m and 1600-1800 m had formed after the river incised planation surface of 2000 m, and the pebble layer underlying the Formation depositing had formed.The ancient Shenyu river run through Jinsha river, entered into the ancient Zhangjiu river, and converged into the Dianchi lake. 4.2-1.1 Ma, Xigeda formation, and Huili and Huidong basins developed.the ancient Cheng river probably converged into Yuanmou basin and began to form Yuanmou formation.These ancient lake in Panzhihua area and Yuanmou did not link.The ancient Shenyu river divagated and flawed eastward, but not run through. 1.1-0.73 Ma, the ancient Shenyu river run through and formed the Jinsha river.Intensive headward erosion took place toward the ancient Cheng river, so the platform did not form in area of 1400 m along Luonong to Jinpingzi of Jinsha river.The ancient Yalong and Cheng rivers converged into Yuanmou basin. 0.73 Ma, the Jinsha river captured the ancient Cheng and Yalong rivers, and run through this area.The developed of Yuanmou formation finished. 0.73 Ma to now, the bank of 1200-1400 m along Jinsha river had formed steep slop under speedy incising of the river.Terraces has began to form since the late middle Pleistocene.
